    An electrical resistivity survey was carried out using the pole–pole configuration around the Sayanokami spring area in the northern part of Ito Campus (Kyushu University, Fukuoka, Japan) to study the groundwater aquifer and its electrical characteristics. A Code Division Multiple Transmission (CDMT) system was used. The CDMT system transmits 24 currents simultaneously and measures 24 potential responses with monitoring of actual current waveforms. The system can inject current from multiple electrodes into the underground environment simultaneously using different individual current waveforms. The two-dimensional (2-D) inversion results of the electrical resistivity data indicate three layers from top to bottom, as follows: a) a thin layer with a thickness of 3 m and a low resistivity (<50 Ω∙m) representing topsoil, b) a groundwater aquifer layer with an average resistivity between 50 Ω∙m and 170 Ω∙m and with a thickness ranging from 7 to 10 m, and c) a highly resistive bedrock layer with resistivities higher than 200 Ω∙m and occupying depths from 15 m to the base of the model.

    A new method is presented for the 3-D forward modelling of the magnetic effects
    (induced magnetization) of a hexahedral (trilinear) prism using the Gauss–Legendre
    quadrature method. The 3-D forward modelling provides an improved application
    to geological problems. The magnetic effect has been evaluated via the summation
    of the effects of the point dipole that fills the volume. The 3-D volume is divided
    into smaller prisms using an appropriate number of nodes. The algorithm is tested on
    two synthetic examples, and the results are compared against calculated data from
    a common program developed at the University of British Columbia–Geophysical
    Inversion Facility, with both tests showing positive results. The results of testing the
    algorithm against two synthetic slab models are also given. Finally, the program is
    applied to a field data set from Aynak-Logar Valley region in Afghanistan. Using this
    program, complex 3-D model bodies may be constructed from hexahedral prisms
    to facilitate the calculation of their magnetic anomalies and magnetic susceptibility.
    Interpretation of the results shows that 3-D constructed models are successful in
    recovering the shape and location of the true model.

    Defining the surface hydrological parameters represents a crucial factor for the sustainable development purposes. In areas with heavy precipitation and rugged topography, these parameters control the occurrence of some natural hazards, from which the flash flood gets the most attention. Traditional methods for the assessment of the surface hydrological parameters are costly, time-consuming and provide information for limited geographic extent. On the other hand, remotely sensed data provide a cost-effective, rapid and wide aerial coverage with adequate accuracy. Geospatial analysis of these remotely sensed data provides a suitable and effective method for the reconnaissance determination of the surface hydrological parameters. In this work, digital elevation models, Landsat 8 satellite images as well as digital maps of soil and land use for Kyushu Island were acquired and analyzed using geographic information system. Surface hydrological parameters were determined in terms of watershed boundaries, soil moisture, initial abstraction as well as flash flood potentiality. Results of this research show a great correlation with historical flash flood events that occurred in the island. The northern parts of the island are subjected to the threat of flash floods. A follow-up is recommended in some areas on the island. As a conclusion, the geospatial analysis performs an accurate reconnaissance method for hydrological analysis at regional scale, which in turn guides the detailed field observation saving time and cost.

    It is important for geothermal exploration to know regional subsurface structures. The gravity survey is often used to narrow down the promising area at the early stage of geothermal exploration. The gravity survey was carried out to estimate subsurface density structure in the Kinigi geothermal field, Rwanda, in September 2015. In order to interpret the gravity anomaly distribution, 3-D gravity modeling was done by using the new program based on Gauss-Legendre integration using hexahedral elements. As the result, the computed gravity anomalies showed high gravity anomalies in northwest, the northeast, and east-southeast of the studied field and low anomalies in the southwest side of the studied field as Bouguer anomalies. The area was characterized by normal contacts with main boundary trending NW-SE direction. This boundary was estimated as main fault in Kinigi geothermal field, Rwanda. The detected fault could be a better place for installing geothermal wells for future geothermal development in the region.

    The Um Salatit is a gold occurrence situated in the Central Eastern Desert of Egypt. The studied area is characterized by an intensive imbrication zone of serpentinites and metavolcanic rocks. The integrated use of aeromagnetic and spectral reflectance remote sensing data has proved effective for mapping geology related to ore deposits. Spectral reflectance maps have been produced to discriminate various rocks, such as serpentinites, gabbros, and metavolcanic rocks. 3-D inversion of aeromagnetic data acquired over the Um Salatit study area produced a 3-D magnetic susceptibility model showing magnetic bodies surrounded by less magnetic host rock. The magnetic features are elongated ENE-WSW parallel to the major thrust fault and mapped the Um Salatit serpentinized rocks. Remote sensing data allow investigating surficial geological features and mapping the mineralized areas. Remote results, in conjunction with 3-D inversion of aeromagnetic data, demonstrate that gold occurrence in the study area was effectively restricted to the highly magnetic zone interpreted as host rocks.

    A land gravity survey was carried out in the Kinigi geothermal field, Northwest Rwanda using 184 gravity stations during August and September, 2015. The aim of the gravity survey was to understand the subsurface structure and its relation to the observed surface manifestations in the study area. The complete Bouguer Gravity anomaly was produced with a reduction density of 2.4 g/cm3. Bouguer anomalies ranging from −52 to −35 mGals were observed in the study area with relatively high anomalies in the east and northwest zones while low anomalies are observed in the southwest side of the studied area. A decrease of 17 mGals is observed in the southwestern part of the study area and caused by the low-density of the Tertiary rocks. Horizontal gradient, tilt angle and analytical signal methods were applied to the observed gravity data and showed that Mubona, Mpenge and Cyabararika surface springs are structurally controlled while Rubindi spring is not. The integrated results of gravity gradient interpretation methods delineated a dominant geological structure trending in the NW-SE, which is in agreement with the regional geological trend. The results of this gravity study will help aid future geothermal exploration and development in the Kinigi geothermal field.

    Magnetotelluric (MT) method is a widely used geophysical method in geothermal exploration. It is used to image subsurface resistivity structures from shallow depths up to several kilometers of depth. Resistivity imaging using MT method in high-enthalpy geothermal systems is an effective tool to identify conductive clay layers that cover the geothermal systems and to detect a potential reservoir. A resistivity model is vital for deciding the location of pilot and production sites at the early stages of a geothermal project. In this study, a 3-D resistivity model of Aluto-Langano geothermal field was constructed to map structures related to a geothermal resource. The inversion program, ModEM was used to recover the 3-D resistivity model of the study area. The 3-D inversion result revealed the three main resistivity structures: a high-resistivity surface layer related to unaltered volcanic rocks at shallow depth, underlain by a conductive zone associated with the presence of conductive clay minerals, predominantly smectite. Beneath the conductive layer, the resistivity increases gradually to higher values related to the formation of high-temperature alteration minerals such as chlorite and epidote. The resistivity model recovered from 3-D inversion in Aluto-Langano corresponds very well to the conceptual model for high-enthalpy volcanic geothermal systems. The conductive clay cap is overlying the resistive propylitic upflow zone as confirmed by the geothermal wells in the area.

    Using advanced geospatial analysis technologies, flash flood risk is assessed for the island of Kyushu, Japan. In this study, the flash flood risk is redefined in terms of the flash flood potential index (FFPI) and the flash flood residential hazard (FFRH). The island experiences rainy weather, especially in the summer (June–August), when catastrophic flash flood events have historically occurred. Studies of the surface hydrological properties of the island are very rare and localized; hence, geospatial techniques are most appropriate for the assessment process. The Soil Conservation Service rainfall-runoff model was used to estimate hydrological responses on the island. Four factors were included in the flash flood assessment. A multi-criteria analysis was carried out to map the FFPI and FFRH from the evaluation factors. The results show that the highest flash flood risk occurs in the northern parts of the island, where the soil displays relatively low infiltration rates and relatively high curve numbers, despite the comparatively low precipitation rates that occur there. The results indicate that soil hydrological properties are the main driving forces of flash floods, especially in regions with low precipitation rates. The results of this research are consistent with previous in situ measurements of runoff made at several sites on the island. The results also show a strong geographic correlation with historical flash flood events on the island. This research validates the use of geospatial analysis for large geographic regions where in situ measurements cannot be taken due to time or cost constraints.

    This paper deals with the application of neural network technique for the three-dimension interpretation of mise-à-la-masse data from the Takigami geothermal field in Kyushu, which is one of the most active geothermal area in Japan. To understand the structure of the geothermal field, a 4-layers neural network had been developed. The training algorithm for the network is back-propagation with five paradigms, e.g. on-line back-propagation, batch back-propagation, delta-bar-delta, resilient propagation (RPROP) and quick propagation, were applied to find out the most efficient one. The network was trained with 3-D mise-à-la-masse simulation data set, including 864 cases of a single anomalous resistivity block of 10 Ohm.m moving in the model mesh with background resistivity of 100 Ohm.m. To generate the training data set, a high accuracy algorithm for 3-D numerical simulation, based on finite difference method and the algorithm of the singularity removal, was used. The trained network was tested by a synthetic data and then applied for the real field data set of the study area. The obtained results are remarkably correlated with the other available data from the field such as previous geoelectrical data, formation temperatures, lost circulation zones, hence, promising zones for production or re-injection can be indicated quickly at site of Takigami geothermal field.

    This study describes radiogenic heat production (RHP) estimated from two sets of well logging data recorded in Rudeis Formation, Belayim marine oil field. Subsurface total count gamma-ray (GR) data were recorded in nine wells, seven of which possessed spectrometric data (eU, eTh, and K). The data show that RHP estimated from GR logs (ABR) varies from 0.13 to 1.73μW/m3, with an average of 0.7μW/m3 and a standard deviation of 0.26μW/m3. In addition, 72.9% of RHP values fall within the range of 0.6-1.0μW/m3. RHP estimated from the concentrations of radioactive elements (AR) vary from 0.13 to 2.1μW/m3, with an average 0.71μW/m3 and a standard deviation of 0.38μW/m3. 50% of these RHP values fall within the range of 0.6-1.0μW/m3. Cross-correlation of ABR and AR calculations yielded a moderate fit of 0.75. The three-dimensional (3D)-slicing of the reservoir shows that the northern and north-western parts of the study area have higher RHP compared to other parts. The estimated RHP can produce enough heat which has an effect on the hydrocarbon potential in Rudeis Formation.

    In this paper, the authors propose a novel exploration system for ocean floor resources using an autonomous underwater glider and OBEM (Ocean bottom electromagnetometer). Studies on the gliding performance and the hydrodynamic characteristics of several kinds of body shape were carried out for the preliminary design of the system. Gliding ratios in a steady flow were estimated based on CFD calculation for different main wing shapes. The effects of the size of the body and the camber of the main wing were examined as well. It was confirmed that designed vehicle had efficient gliding performance to achieve the autonomous OBEM measurement.

    This paper presents a fast algorithm for electromagnetic data inversion to three-dimensional (3D) resistivity models. The algorithm is distinctive for the level of accuracy it attains while bypassing the sensitivity matrix update. A common sensitivity matrix for homogeneous half-space is used in all iterations. Instead of updating the sensitivity matrix, the smoothness filter coefficients at each model element are updated, based on the spatial variations in resistivity in the model derived from the latest iteration. This substitution is expected not only to reduce the computation time required for large-scale inversions, such as those for 3D surveys, but also to allow the resolution of sharp boundaries in resistivity structures. Our algorithm was applied to 3D magnetotelluric inversion in order to confirm its effectiveness. Using synthetic examples under several conditions, we demonstrated that the method can reduce the number of forward calculations required to reduce data misfits to noise level, and that the method is robust for constructing target models even with sharp boundaries without generating fatally false resistivity structures or boundaries under noisy conditions.

    This study evaluates the use of image processing techniques and methodologies of digital integration of multi-disciplinary geoscientific data to reduce the ambiguity in geological interpretations in different geological environments in Libya. To realize this objective, three areas were selected for this study; Eljufra, an arid environment; the mountainous environment Tarhunah; and the Jifara Plain, a coastal plain environment. Two types of remote sensing data were used in this study: Landsat Enhanced Thematic Mapper Plus (ETM+) and European Remote Sensing Satellite. The digital elevation model extracted from Shuttle Radar Topography Mission and digital topographic maps scale 1:50,000 were used for remote sensing interpretation. GIS and remote sensingbased methods were used to process and integrate all raster and vector layers data. This study offered dramatic benefits for geological interpretations and provided new insights into the efficiency of image processing methods in different geological environments.

    An advanced geoelectrical technique for imaging potential fractures has been developed by Engineering Geophysics Laboratory in Kyushu University. The method, Fluid Flow Tomography (FFT), has been applied to monitor fluid flow behaviors in a reservoir during water injection and steam production operations in geothermal areas. Distribution and extension of major fractures can be evaluated by 3-D inversion of induced self potential (SP) anomalies with a function of time and resistivity structures can be determined by 3-D inversion of the charged potential data in a surveyed area. It is concluded that fluid flow behaviors in a reservoir could be continuously traced and visualized as a function of time by the FFT method.

    Several geophysical exploration methods have been applied to the problem of detecting and mapping underground archaeological remains with practical success. The most productive techniques are those for which the archaeological target exhibits the great physical contrast with the surrounding formation. Most widely used in archaeological prospection include Magnetic, Electromagnetic, Ground Penetrating Radar and Electrical Resistivity methods applied at the shallow surface. However, these conventional geophysical measurements for an archaeological prospection has been tried with relatively limited success. Therefore, we have developed an automatic imaging system named as Handy-ARM (Archaeological Resistivity Meter) for an archaeologist based on electrical resistivity techniques.

    Mine clearing is an urgent matter to be tackled internationally not only from the humanitarian point of view but also from the viewpoint of reconstruction and economic growth in the area where a cessation of armed conflicts was achieved. Operations are already underway to clear landmines, but currently they rely heavily on human works due to a lack of safer and efficient demining techniques. Various geophysical exploration techniques have been applied to the problem of detecting and mapping underground mines and UXO with practical success. The most productive techniques are magnetic, electromagnetic and Ground Penetrating Radar methods for which the mine target exhibits the greatest physical contrast with the host geological formation. Developments of more sensitive geophysical equipments for detecting mines is required to meet the geophysical conditions of lower contrast with the environment and at the scale of the target. Starting from May 2004, a channel of communication between the Egyptian embassy in Tokyo and the Kyushu University Mine Action Group (QMAG) team on the topics of landmines in Egypt has been established on how to apply geophysical techniques newly developed geophysical techniques in Japan to solve the problem of landmines in Egypt. We arranged a campaign for landmines detection technology in Egypt, conducted by research teams of QMAG of Kyushu University. During the campaign three geophysical techniques, DC resistivity, magnetic and ground penetration radar were tested and evaluated.

    Sibayak geothermal field is located about 65 km to the southwest of Medan in the North Sumatra Province, Indonesia. Starting from 1998, a small-scale geothermal power plant (2 MWe) has been installed in this area. Since electricity demand increases in the North Sumatra Province, Pertamina Geothermal Energy plans to increase the capacity to 20 MWe. Accordingly, detailed knowledge of the reservoir structure and its extension must be determined for a new production target. The mise-a-la-masse (MAM) surveys were carried out in this field using the exploration well SBY-1 and the production well SBY-4 to delineate a new production target for further field development. A conventional one-dimensional MAM data processing has been done to obtain lateral variation of subsurface resistivity. However, the result is not satisfied to image real condition of the geology on the subsurface. Therefore, we carried out an advanced 3-D MAM inversion based on the smoothness-constrained least-squares method using a homogeneous earth as the simplest assumption of the starting model. Interpretation of the 3-D MAM model was done by combining the results with previous geo-electrical data and borehole information to image a promising reservoir zone. The resistivity model obtained from this study is characterized by a very low resistivity cap rock beneath a resistive layer and rather high resistivity layer of the reservoir. The very low resistivity layer is due to clay minerals such as montmorillonite. This interpretation result of the 3-D MAM model indicates that reservoir zones trend to the north-northeast direction of the study area, between Mt. Sibayak and Mt. Pratektekan, and shows a good correlation with the formation temperature and the lost circulation zone. This geophysical information is useful for the task of selecting sites for the promising zone in the Sibayak geothermal field.

    This paper deals with the application of neural network technique for the three-dimension interpretation of mise-à-la-masse data from the Takigami geothermal field in Kyushu, which is one of the most active geothermal area in Japan. To understand the structure of the geothermal field, a 4-layers neural network had been developed. The training algorithm for the network is back-propagation with five paradigms, e.g. on-line back-propagation, batch back-propagation, delta-bar-delta, resilient propagation (RPROP) and quick propagation, were applied to find out the most efficient one. The network was trained with 3-D mise-à-la-masse simulation data set, including 864 cases of a single anomalous resistivity block of 10 Ohm.m moving in the model mesh with background resistivity of 100 Ohm.m. To generate the training data set, a high accuracy algorithm for 3-D numerical simulation, based on finite difference method and the algorithm of the singularity removal, was used. The trained network was tested by a synthetic data and then applied for the real field data set of the study area. The obtained results are remarkably correlated with the other available data from the field such as previous geoelectrical data, formation temperatures, lost circulation zones, hence, promising zones for production or re-injection can be indicated quickly at site of Takigami geothermal field.

    A magnetotelluric (MT) survey has been carried out in Takigami geothermal area to determine resistivity structures and the locations of electrical discontinuities that may reflect a possible fault or fracture correlating with promising geothermal reservoir. The MT measurements have been conducted with irregular grid stations covering the Takigami area. The two-dimensional (2-D) inversion results of the MT data show that the resistivity structures in Takigami area are composed mainly of three layers, that is, high resistivity in the first layer overlying low resistivity in the second layer and resistive electrical basement in the third layer. The results are also in a good agreement with electrical resistivity logs, temperature distribution and lost circulation zone during the course of drilling. It is revealed from the interpretation of MT data that the geothermal reservoir of Takigami field is located at two different depths separated by Noine fault zone, which divides the subsurface of the area into eastern and western parts according to the characteristics of resistivity, permeability, temperature and depth of reservoir. The reservoir in the east of Noine fault zone is shallower than that in the west.

    DC resistivity method is commonly used for acquiring subsurface resistivity data in environmental and engineering investigations. However, its interpretation is hampered by a variety of factors of which the non-linear nature of the process and bias effects on the data; mainly due to the noise; are the most problem, which limit the model resolution to a large extent. The ability to invert resistivity data successfully depends on many factors such as the uniqueness of the model as well as the robustness of the inversion algorithm. Hereafter we are investigating this problem using three different 1-Diversion algorithms. The three algorithms have been applied to a numerical model of 4 layers to determine the optimum solution produced by each of them. A random noise of 5, 10 and 20 percents has been added to the model in a forward step to determine the most stable, robustness algorithm. Those algorithms have been applied to the field data set measured at Hamam Faraum hot spring area, Egypt, aiming to make a refinement to the previous 1-D inversion done before for the same data set (E1-Qady et. al, 1998). We could conclude that the algorithm of Meju, (1992), is the most effective one in this study. The resulted 1-D geoelectrical cross section could elucidate the subsurface structure and explain the origin of the hot water in the area.

    A multichannel geoelectrical system and software for data acquisition, processing and interpretation was developed. The method, called fluid-flow tomography (FFT), was used for direct imaging of fractures and an extension of geothermal reservoirs, and to monitor an oil reservoir during thermally enhanced oil recovery. The fluid-flow behavior in the subsurface can be monitored and visualized by the technique, providing time-series data of charged potentials and self-potentials, fluid-flow fronts visualizations and quantifications, symmetric anomaly due to anisotropic permeability of the formation, and 3D fractures distribution.

    An advanced geophysical technique for reservoir monitoring by electrical prospecting has been developed by the joint research of Kyushu University and CRIEPI work in related to fracture evaluation at the Hot Dry Rock Geothermal Power Project in the Ogachi area. The Fluid Flow Tomography survey method utilizes a casing pipe itself as a charged current electrode similar to the mise-a-la-masse method. The method has been applied to monitor fluid-flow behaviors during massive hydraulic fracturing operations and fluid-circulation experiments from injection to production boreholes. In the automatic recording system controlled by a personal computer charged potentials (mV/A) and spontaneous potentials (mV) can be simultaneously measured as a function of time at multiple stations (120ch) surrounding an operating borehole. Fluid-flow behavior in the subsurface could be visualized as a function of time by using contour maps of residual potentials from SP data and relative changes of apparent resistivity due to dynamic reservoir stimulations.

    Hydraulic fracturing experiments for making a man-made reservoir have been conducted on HDR project by CRIEPI since 1986. The Vertical Electric Profiling (VEP, hole-to-surface) method of the geotomography has been applied to monitor fluid-flow behaviors during massive hydraulic fracturing operations. Self potentials (streaming potentials) and charged potentials (apparent resistivities) were continuously observed at multiple stations on the ground surface before and during pumping operations for estimating fluid-flow front and fracture extents. The injected fluid-flow was continuously imaged as a function of time with a personal computer on the Hot Dry Rock site.

The injection/production fluid-flows were continuously monitored with multiple potential electrodes on the ground surface surrounding the well. The potential data are measured with every 2 sec intervals by the digital recording system controlled by a personal computer on the site. The distribution of fractures estimated from the detected potentials show good agreements with the geometry of major fractures determined by the previous VEP (hole-to-surface) surveys in 1984 and the modern magneto-telluric survey in 1987.

    Many engineering disasters are related to water infiltration in cracks. Understanding the water infiltration in multi-layered sandstone cracks is crucial for monitoring and preventing water-related disasters in coal mines. In this study, we utilized the electrical resistivity tomography (ERT) technique to conduct a water infiltration monitoring experiment on the 2d-strata-model with cracks. The electrical resistivity ratio profiles with respect to the background unveiled the existence of three cracks. Model photography demonstrates two cracks of those cracks. The infiltration cracks exhibit distinct shape of a stripe or island chain electrical change ratio anomaly in the resistivity ratio profiles. Electrical resistivity change ratio is associated with the infiltration within the cracks. As the infiltration progresses, the resistivity change ratios relative to the background gradually decreases. This is evident in the reduction in ratios in the original stripe or island chain areas in the electrical resistivity ratio profiles. The diminished range expands, manifesting as an increase in the area of the original stripe or island chain. The infiltration patterns of the cracks can be categorized into three types: a stripe pattern, island chain and stripe pattern, and island chain pattern. The preferential flow paths along the crack are related to both the infiltration time and the volume of infiltration. In the early stages, there are clear preferential flow paths along cracks. However, as infiltration time and volume increase, these preferential flow paths along the cracks become less pronounced and may even disappear. The findings prove that ERT is suitable for monitoring water infiltration along the cracks in multi-layered sandstone in the early infiltration stage. Experiment results monitoring water infiltration cracks on the 2D-model show that the ERT and 2D-model are suitable for studying water infiltration along the cracks. This research can provide valuable reference for preventing engineering disaster.

    To map the region's geology and mineral exploration, this study looked at how remote sensing satellite imaging from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Thermal Infrared (TIR) sensor and aircraft geophysics may be used. The Francistown region forms part of the Zimbabwe craton, northeast of Botswana. It comprises felsic rock types, including granite and dry river sand, mafic-ultramafic rocks, and gneiss country rock. Based on their spectral emissivity responses, mafic-ultramafic units and quartz-rich units were discovered. These units are important targets for the discovery of mineral resources. The research region can be described as convoluted, fractured, intruded, metamorphosed, and ultimately worn from a geological and geophysical standpoint. Several remote sensing and aeromagnetic approaches were employed. The false color composite (FCC) and mineral indices using ASTER TIR data provided helpful information for delineating the area's geology and concentration of major-rock-forming minerals. The aeromagnetic data extracted lineaments well, and the Center for Exploration Target (CET) grid analysis system was very helpful. The CET Porphyry Analysis technique was applied in mapping near-circular porphyry features, which are good indicators of possible sites with high mineralization potential. The analysis of the lineament map shows that mineral deposits are mostly along the NE-SW direction. The results from the ASTER TIR and aeromagnetic enhancements indicate the occurrence of mafic-ultramafic rocks and felsic-rich units, which have been documented to host mineralization in the region. Porphyry structures are also mapped successfully along the general strike of the geological structure in the study area. The combination of these methods proved their success, and they can be used further in other regions of high mineral potential and lithological mapping for their cost efficiency and reliability.

    Mount Lawu is a stratovolcano located on the border of Central Java and East Java Provinces in Indonesia. At least eleven manifestations indicate its geothermal potential in the form of hot water and fumaroles. This study aims to describe a geothermal system based on an integrated analysis of magnetotelluric (MT) and satellite gravity data. Some additional geochemical and petrological data analyses were also used to explain the existing hydrothermal system in this area. It is inferred from the gravity derivative analysis that fault structures exist in a location with high permeability, which acts as a controlling structure for geothermal manifestations. The 3-D resistivity inversion was carried out using MT full-impedance tensor data, while the 3-D density model was reconstructed based on the residual anomaly computed from the topography-free gravity disturbance. The 3-D resistivity model, from magnetotelluric inversion, shows a clay cap distribution, corresponds to a low resistivity anomaly, centered at the southern part of the mountain peak with a thickness of about 1 kilometer, which narrows to the western region where the hot spring shows an outflow manifestation. The gravity inversion shows several low-density bodies in the same location as the low-resistivity anomaly attributed to a clay cap. Coincident resistivity and density anomalies constrain the horizontal location of the geothermal reservoir. Despite the incapability of the model to resolve the body of the geothermal heat source, it can be inferred from the inversion results that the heat possibly emanates through the thermal conduction passage below the reservoir zone from the source located deeper down than the reconstructed models.

    The Panjshir Fe-Polymetallic ore deposit is a valuable geological resource in Afghanistan, rich in iron and multiple essential metallic minerals, with substantial potential for industrial development. The exploration phase faces challenges related to the complex geological settings, high variability of mineral compositions, and the need for advanced geophysical techniques to accurately locate and assess valuable metallic resources. Considering the strong magnetic characteristics exhibited by Fe-Polymetallic elements, geomagnetic data were employed to analyze and map the likely prospectivity of Fe-Polymetallic deposits within the study area. Multi-scale edge detection techniques were employed to accurately map the boundaries of magnetic bodies by utilizing the upward continued analytical signal amplitude. The presence of a fault system on the geological map confirmed the structural information derived from our edge detection techniques. Advanced magnetic data inversion techniques were employed to create a three-dimensional representation of the distribution of magnetic bodies linked to Fe-Polymetallic deposits. In our efforts to reduce the impact of remnant magnetization in the study area, we adopted a comprehensive strategy by employing both magnetic susceptibility and magnetization vector inversion techniques. The use of a sparse and blocky norm regularization [0,1,1,1] is well-suited for magnetic susceptibility inversion, while a blocky norm [0000,0000,0000] is the appropriate choice for magnetization vector inversion in our study. Ultimately, the zones characterized by a high magnetic susceptibility and a high magnetization amplitude are considered promising areas for potential Fe-polymetallic occurrences.

    Water percolation usually occurs in soil, making it highly challenging to simultaneously monitor and verify the water percolation process in real-time. We propose employing electrical resistivity tomography and the photography technique, respectively, to visualize and validate water percolation. An experiment was conducted to monitor water percolation in sand within a transparent glass trough using electrical resistivity tomography (ERT) and photography techniques. The experimental results show that the relatively low-resistivity anomalies in the electrical resistivity profiles and correction electrical resistivity profiles, derived from the experimental data, have a half-ellipse shape, while the wetting areas captured in the photographs exhibit a bulb-shaped pattern. The relatively low-electrical-resistivity anomaly areas delineated by the 2000 Ω·m contour line in the electrical resistivity profiles and the 120 Ω·m contour line in the correction electrical resistivity profiles exhibit a remarkable correspondence with the wetting areas captured in the simultaneous photographs. Our findings show that the ERT and photography techniques are suitable for the real-time monitoring and simultaneous verification of water percolation in sand within a narrow glass trough.

    The Koh Safi Chromite Ore Deposit is located in Afghanistan’s northern–northeastern end of the Kabul–Kandahar ophiolite zone. Sedimentary formations, delayed volcanic, and ultramafic rock groups, including peridotites and serpentinites, could all have been found in the Koh Safi area, where structural discontinuities with the two trends of northwest–southeast and east–west can be identified. High-grade serpentinite units have many chromite deposits, whereas peridotite has a lot of medium-grade deposits. This paper performs a ground magnetic data analysis based on structural analysis and 3-D susceptibility inversion. The boundaries of structural faults and anomalous bodies are likely delineated in a northwest-to-southeast orientation using a series of derivative maps, including Total Horizontal Derivative, Analytical Signal, and Theta Map. For inversion, many regularization norms that included the range of smooth, intermediate, and compact models were used to examine a particular susceptibility value that occurred in a model cell. The sparse and blocky norms [0,1,1,1] were suggested for our inversion in field data based on synthetic data to determine an appropriate norm. A 3-D inversion of ground magnetic data shows that the highly magnetic zone supposed to be the host rocks seems to be where chromite occurs in the study area.

    Electrical resistivity and induced polarization (ER-IP) surveys were carried out in Eastern Labo, Bicol, Philippines, to assess the potential Cu-Au mineralization in pyroclastic-covered areas. An electrical resistivity tomography method with a dipole–dipole array was used, and the L1 norm (robust) inversion approach was employed to generate the 16 2D ER-IP models. The analysis of the resistivity and chargeability classified the underlying lithology into eight zones. Zones from C to F are the potential mineralized zones, while Zones A and B (Labo Volcanic Complex) and Zones G and H (Tumbaga Formation and Tamisan Diorite) are the non-mineralized zones. Zone C, represented by low chargeability (<15 mV V−1) and intermediate resistivity (15–100 Ω-m) values, is characterized by a high concentration of disseminated sulfide minerals (e.g. chalcopyrite). Zone D has a chargeability range comparable to Zone C but higher resistivity (>100 Ω-m), which might be due to silicification. Zone E corresponds to the oxide zone with concentrated sulfide minerals along clayey, weathered, fractured areas; it has moderate to high chargeability (>15 mV V−1) and low resistivity (<15 Ω-m) signatures. Zone F has a similar resistivity range to Zone E but has lower chargeability (<15 mV V−1) values. The interpreted underlying lithological units were confirmed using borehole data. Because of the extensive occurrence of high chargeability zones with moderate resistivity anomalies, potentially mineralized areas for further investigation (e.g. drilling) were identified in the north-eastern portion of the study area.

  • Electrical resistivity structure of Danau Ranau geothermal prospect area based on integrated 3-D Inversion of impedance tensor and tipper vector*

    Subsurface electrical resistivity distribution needs to be revealed to explore the geothermal potential in The Danau Ranau prospect area, as the components in geothermal systems could be easily characterized by their resistivity contrasts. The magnetotelluric method is a geophysical method commonly used to perform this task. This paper performs a three-dimensional inversion based on the complete component of magnetotelluric transfer functions, including impedance tensor and tipper vector. Prior dimensionality analysis using phase tensor revealed that the MT data contains a high dimensionality distortion and shows significant horizontal geoelectrical variations. The analysis suggests using the MT full components in the inversion process to effectively recover all the geoelectrical features in such a geologically complex area. The three-dimensional inversion was then carried out after taking control of the model mesh dimension and the regularization parameter. The 3-D resistivity model showed an overburden layer with varying resistivity in the shallow depth. In the subsequent layer, a conductive anomaly representing impermeable cap rock is distributed from the center to the northern and western parts of the study area, bordered by faults and manifestations. The reservoir zone is located under the center of Mount Seminung at an approximate depth of 1500 m. The heat source is expected to be the residual eruption magma of the volcano, which sits far under the reservoir zone and is unreachable by the MT signal. All the findings agree with the existing geological and geochemical survey data and can explain the hydrothermal activities in the Danau Ranau geothermal prospect area.

    Magnetotelluric (MT) field data contain natural electromagnetic signals and artificial noise sources (instrumental, anthropogenic, etc.). Not all available time-series data contain usable information on the electrical conductivity distribution at depth with a low signal-to-noise ratio. If variations in the natural electromagnetic signal increase dramatically in a geomagnetic storm, the signal-to-noise ratio increases. A more reliable impedance may be obtained using storm data in a noisy environment. The field datasets observed at mid-latitudes were used to investigate the effect of geomagnetic storms on MT impedance quality. We combined the coherence between the electric and magnetic fields and the result of the MT sounding curve to evaluate the MT impedance quality across all periods and combined the phase difference among the electric and magnetic fields, the polarization direction, and the hat matrix to discuss the data quality for a specific period simultaneously. The case studies showed that the utilization of the data observed during the geomagnetic storm could overcome the local noise and bring a more reliable impedance.

    In this research, we figure out the lithospheric structures of the western U.S. and assess its tectonic implications with a high resolution using dense gravity data. Gravity data with high spatial resolution enables detailed mapping capabilities, overwhelming other geophysical data. To investigate the physical basis for support of topography in the western U.S., we employed the parker-Oldenburg algorithm to gravity to calculate the depth to Moho. The estimated depth to Moho shows an excellent spatial correlation with the physiographic provinces in the study area following an eastward thicking pattern. Moho of the stable craton reaches 50 km, whereas the western margin shows a shallow Moho of 20 km. Moreover, to assess the tectonic implication of Moho in the study area, we calculated the crustal compensation load to evaluate the isostatic state in the study area. The calculated compensation loads provide isostatic compensation for large-scale crustal structures, such as the broad, elevated Basin and Range Province. To assess the contribution of the crust and mantle to the topographic deformation in the study area, we calculated the crust topography and mantle topography. The Wyoming Craton and Great Plains have negative mantle topography values, contrasting with the relatively constant values in the southern Rockies, Colorado Plateau, and Basin and Range. Crustal topography reveals significant crustal support from the southern Rockies and the Wyoming craton. In addition, we estimated the lithospheric mantle thickness and the depth of the Lithosphere–Asthenosphere Boundary (LAB); the mantle thickness has values reaching 90 km at the stable eastern craton with LAB depth reaching 140 km. This research demonstrates the effect of the tectonic regime on the study area and the implications of this tectonic on the lithospheric structures with a high spatial resolution of a few hundred meters.

    In geothermal exploration, the subsurface temperature distribution is an important parameter since it is closely related to the existing geothermal system. However, subsurface temperature information can only be obtained from boreholes, requiring a considerable cost and a limited number. A new geothermometry technique based on the relationship between temperature and resistivity has been proposed to overcome this difficulty. In order to enhance the reliability of this method, the subsurface heat condition in a different geological and geographical location was reconstructed. The temperature up to some depth beneath the surface could be estimated incorporating the back-propagation neural network using resistivity determined by high-resolution audio-magnetotelluric soundings. The temperature profiles resulting from the neural network fit with those observed from nearby boreholes, providing a satisfying evaluation result of the model’s predictive powers. Joint interpretation was then carried out following the one-dimensional resistivity inversion result and temperature cross-section. Both resistivity and temperature anomalies show an excellent agreement, so that subsurface anomaly such as altered layers, reservoir zone, and some possible faults was detected. With an appropriate training strategy, this technique can help to significantly reduce the costs at estimating the subsurface temperature.

    The Zeit basin is located on the western coast of the Gulf of Suez. It is a major, elongated half-graben structure with faults dipping steeply to the southwest. The Zeit basin contains the thickest Miocene sediments and evaporites in the Gulf of Suez. Many exploration activities have been conducted in and around the study area due to the known presence of hydrocarbon resources. In petroleum exploration, the estimation of basement depth (or sedimentary thickness) is a primary exploration risk parameter, in particular, for estimation of heat flow. The magnetic method is one of the few methods that can be used to study the basement structure and estimate the top basement depth. In this paper, the top basement geometry, distribution of the magnetic susceptibility and the basement depth of the Zeit basin were investigated using 3-D forward magnetic modeling and the 3-D inversion of geo-magnetic data. The 3-D forward modeling of the aeromagnetic field data from the Zeit basin area revealed a NW-SE trending half-graben structure, consistent with the known geology of the study area. Magnetic susceptibility cutoff 0.005 SI was applied to show the subsurface relationships among the basement sedimentary units. The calculated depth of the Zeit basin is around 4–5 km. The magnetic field data, calculated using the Gauss Legendre quadrature method, generally agree with the measured data as well as data calculated using the inversion process. The depth and magnetization intensity values used in the 3-D forward modeling, as well as petroleum borehole data, provide a structural basis for the 3-D inversion process.

  • 3D constrained gravity inversion to model Moho geometry and stagnant slabs of the Northwestern Pacific plate at the Japan Islands

    The motivation for this work was to model the crustal thickness, and the geometry of the Mohorovičić (Moho) discontinuity, the crust-upper mantle boundary around the Japanese archipelago. The western Pacific Ocean is one of the most eminent subduction zones in the world. The subduction zone complexity is due to alteration within the geometry of the stagnant slab. We compiled a three-dimensional density distribution model for subduction plates around the Japan Islands, and estimated the depth to Moho using the constrained non-linear inversion of gravity data derived from the latest Gravity field and Ocean Circulation Explorer, or GOCE, model known as GOCO06s. The study had three steps, starting with the data corrections followed by the inversion, and ending with the modeling and comparing of the estimated results with previous models and studies. In this study, we used available receiver function results, seismic tomography models, global crustal thickness, and geological and tectonic information as constraints. The model estimated the crustal thickness, surface geometry of the Moho, and geometry of the stagnant slab in the Kuril Trench, Japan Trench, Nankai Trough, and Izu-Bonin Trough. In gravity inversion, we used 34 km and 600 kg m−3 as the Moho depth reference and density contrast, respectively. Results showed that the crustal thickness ranged from 14 to 43 km with a − 0.78 mean misfit for Moho depths derived from seismic P-wave analysis. The calculated gravity data had a 0.16 mGal misfit with the observed data. The normalized analytical signal helped to sharply delineate the different plates and their edges. Three cross-sections were conducted to model the stagnant slab along the subduction zone of the Eastern Eurasian plate, western Pacific plate, Okhotsk plate, and Philippine Sea plate. The eastern area of the entire region (Pacific plate) had a low crust thickness and high density compared to the western area (Eurasian plate), which had a high crust thickness and low density.

    The Philippine archipelago is a complex island arc system, where many regions still lack geopotential field studies. The high-resolution isostatic anomaly and free-air anomaly digital grids from the World Gravity Map (WGM) were processed and analyzed to present a general discussion of the Philippines’ gravity signatures and contribute to understanding its regional geology and tectonics. The isostatic anomaly map was continued upward to investigate the high-density ophiolitic basement rocks and low-gravity sedimentary basins at depth. The first vertical derivative (1VD) filter was applied to the free-air anomaly grid map to locate regional structures represented by density contrast boundaries. The depth to the top of the Moho and basement rock over the Sulu Sea was computed using the two-dimensional (2-D) radially averaged power spectrum analysis. Three-dimensional (3-D) gravity inversion was applied to some major sedimentary basins in the Philippines to present 3-D subsurface density contrast models. The interpreted gravity maps highlighted prominent geologic features (e.g., trench manifestation, ophiolite distribution, basin thickness). The negative isostatic anomalies (< 0 mGal) represent the thick sedimentary basins, while the moderate signatures (0 to 80 mGal) correspond to the metamorphic belts. The distinct very high-gravity anomalies (> 80 mGal) typify the ophiolitic basement rocks. The gravity data’s upward continuation revealed contrasting deep gravity signatures; the central Philippines with continental affinity (with 20–35 mGal) was distinguished from the regions with oceanic affinity (with 45–200 mGal). The 1VD map over the Sulu Sea showed anomalies associated with shallow features dominantly related to the Cagayan Ridge. The 2-D radially averaged power spectrum analysis exposed gravity anomalies with tectonic significance (e.g., basement characterization, Moho depth estimation). The estimated average Moho depth in the Sulu Sea is from 12 to 22 km, while the average basement depth is within the range of 5 to 11 km. Lastly, the 3-D subsurface density contrast models characterized the very low-density zones representing the deep (> 7 km) sedimentary basins in the northern Cagayan Valley and southern Central Luzon basins. Furthermore, thin (~ 3.5 km) sedimentary formations are inferred for the low-density areas in northern Agusan-Davao and eastern Cotabato basins. [Figure not available: see fulltext.].

    <p>It is important to evaluate materials' strength and damage state in material mechanics. A series of inspection techniques called non-destructive testing is used to examine the state of such materials non-destructively. Non-destructive testing is an inspection technique that examines harmful damage to the interior or surface of an object without destroying the object. It can be broadly classified into methods to detect internal flaws by injecting radiation or ultrasonic waves into the object and methods to detect surface flaws by passing an electric current or magnetic flux near the surface. Non-invasive inspection is a method similar to non-destructive testing—however, non-invasive inspection targets humans, not objects. Non-destructive testing is used for our safety and security, and non-invasive testing is used for our health. Although non-destructive testing and non-invasive inspection are not directly related to geophysical exploration, they share many of the same underlying principles. Geophysical exploration targets subsurface structures, including underground resources such as oil, natural gas, and metal deposits, and is used for our wealth and comfort. Geophysical exploration can be thought of as an inspection technology for the subsurface. In this paper, geophysical exploration for the exploration of subsurface structures and resources is reviewed, and its relevance to nondestructive testing for material mechanics is explained. This paper provides an overview of non-destructive testing and geophysical exploration concerning the mechanics of materials. While non-destructive testing focuses only on flaws within a material, geophysical exploration focuses on the physical properties of the material as a whole, which may be useful for investigating material heterogeneity. I hope this paper has stimulated your interest in non-destructive testing and geophysical exploration.</p>

    Deep Magneto-Telluric (MT) and Mise-a-la-Masse (MAM) geophysical imaging methods provide valuable information on fundamental processes within a geothermal field. However, because of an inherent non-uniqueness problem during data processing, interpretation of each individual method sometime has no good agreement with a real geological structure in a geothermal field. As a result, the naive application of the methodology can lead to erroneous results. Therefore, to convince the interpretation result by decreasing non-uniqueness possibility, we have performed integrated inversion of MT and MAM data observed in the Sibayak geothermal field, Indonesia. The results were then correlated to borehole data. The final interpretation show a dome-shape structure of the low resistivity, indicating an up-flow zone around fractures in the southeast direction of the Sibayak Mountain. This geophysical information is useful for the task of selecting sites for the promising zone in the Sibayak geothermal field.

    Application of geophysical methods has increased to investigate near-surface horizons of interests in related to environmental and engineering geophysics because geophysical methods are cost-effective and large areas can be quickly surveyed at relatively low cost without borings and trench excavations. The most productive geophysical methods are Ground Penetrating Radar and Electrical Resistivity methods for which the target exhibits the greatest physical contrast with respect to the surrounding formations. However, the geoelectrical geophysics is very difficult to predict the sub-surface using conventional techniques because of the shortage of the resolution. These geophysical techniques have required upgrading of data acquisition accuracy of the methods using a multichannel resistivity tool such as Handy Archaeological Resistivity Meter developed by the joint research of Kyushu University and OYO Corporation in Japan. Geoelectrical methods have the economic advantages to solve various archaeological problems. However, there was no successful 3D computer program required for interpreting observed apparent resistivity data. In the present paper, a robust 3D computer program was developed and applied to archaeological prospection. Results of 3D inversion of VES data are compared with the results of GPR method and evaluated with archaeologists of Archaeological Society of Japan.

    Fluid Flow Tomography (FFT) method is an improved mise-à-la-masse method, which is used as a reservoir monitoring method. This method is a 4-Dimensional (4-D) electrical method in order to visualize the transient subsurface fluid flow by measuring charged electric potentials due to subsurface resistivity and streaming potentials caused by subsurface fluid flow. This method is utilized to monitor the fluid flow during hydraulic fracturing of Hot Dry Rock project and periodical overhaul of geothermal power plant. This method is also used to monitor the flow of heavy crude oil in oil sand formation during thermal Enhanced Oil Recovery (EOR). The observed data of FFT method can be separated into charged electric potentials derived from subsurface resistivity structure and streaming potentials due to a permeable fluid flow. In this paper we describe the algorithm of three-dimensional resistivity inversion and three-dimensional probability tomography of self-potential data. A case study of FFT method was carried out in the Onuma geothermal area. As the results of 3-D analysis of resistivity data, distinguished low resistivity anomalies were detected and resistivity discontinuities where marked with resistivity changes were detected. As the results of 3-D analysis of self-potential data, the main production zone and reinjection zone were delineated from Charge Occurrence Probability (COP) distribution. We believe that the FFT method is a useful tool to monitor the dynamic change of fluid flow behavior in a reservoir during production and reinjection operations.

    For Hot Dry Rock (HDR) geothermal energy development, it is necessary to establish techniques for creating artificial fractures and for evaluating a man-made circulation system as geothermal reservoirs. In this study, we have developed the Fluid Flow Tomography (FFT) technique using the Vertical Electric Profiling (VEP/hole-to-surface) method in which a casing pipe of fracturing well can be used for a current electrode. The fluid flow behavior was continuously detected and monitored with 30 stations on the ground surface during massive hydraulic fracturing operations. The VEP method provides lateral distribution of major fractures with time, while the crosshole (hole-to-hole) survey gives informations on fracture depths connected among the injection and production wells. Therefore, we can image the fluid front with time variations and major fractures in three-dimentions by the joint use of VEP (hole-to-surface) and crosshole (hole-to-hole) surveys on the HDR project.

    The underground detection of cavities is one of the most important problems for mining engineers. The mise-a-la-masse (charged potential) and pole-dipole resistivity surveys are investigated for locating natural and artificial cavities. These new geophysical methods have better resolution on the exploration targets than the conventional electrical resistivity methods. It is confirmed that the mise-a-la masse resistivity measurements are very useful for detecting and mapping the lateral changes of the formations such as cavities and fractures. The pole-dipole resistivity method has a good resolution for determining the size and depth of the anomalous body. Therefore, the combined use of these economic geophysical methods provides better resolution of locating the target of interest in three-dimensions. -Authors

    In March and April 1984, West Japan Engineering Consultants (WJEC) was contracted by Kyushu Elec-tric Power Company (KEPCO) to conduct field survey for a proposed mise-a-la-masse method. The survey was carried out using an exploratory well HT-8 located in the vicinity of the present production area of the Hatchobaru geothermal field in north central Kyushu, Japan. The apparent resistivity and potential maps derived from the data processing clearly indicated several promising zones of low resistivity including the present production zones where the almost all of productive wells located inside and indicated two-dimensional structure across the strike of the Komatsuike sub-fault. Two-dimensional mise-ä-la-masse modeling of surface potential and apparent resistivity profiles has been developed over various bodies for multiple electrode configurations. The surface responses are obtained by the finite difference method for a horizontal body with the contrast in conductivity between the body and subsurface is 10:1, but different locations of a line sources of current electrode. A two-dimensional model has been derived to simulate results as close to observed field data across the present production zone as possible. The similarities between the observed data and the best fitted model are striking, in particular of the data for the surface potential distribution.

    The mise-a-la-masse survey has been used mostly for the ore prospecting in the mining industry. In 1984, the mise-á-la-masse survey was carried out using a casing pipe of HT-8 well in Hatchobaru geothermal area in order to map geothermal reservoirs. The measurement gave rise to the sharply contoured residual anomalies due to high contrasts of resistivities among the geothermal fluid, hydrothermaly altered zones and surrounding formations. The residual maps derived from the data processing clearly indicated several promissing low resistivity zones including the present production zone where the almost all of productive wells located inside. It was confirmed that the strike of faults which regulated the upstream of the geothermal fluid and lateral distribution of geothermal reservoirs showed a good correlation with those determined by the Schlumberger resistivity and magnetotelluric surveys in this area.

    When resource fluids flow underground, flow currents are generated underground in response to that flow. Secondary magnetic fields induced by the flow currents are also generated. The fluid flow electromagnetic method is a method to estimate the direction of subsurface fluid flow from the electromagnetic field changes caused by such underground fluid flow.
    In order to implement this method, it is necessary to measure the two-component horizontal electric field and three-component magnetic field simultaneously at the ground surface. In this study, we developed a measurement system for fluid flow electromagnetic exploration using MI sensors based on the magneto-impedance effect. In the newly developed system, the measuring device is designed to be small enough for simultaneous observation of multiple observation points and to allow long-term measurement with low power consumption.

Outline of Social Contribution and International Cooperation activities

  • 物理探査学は地下を非破壊で可視化(イメージング)するための手法であるため,民間等との共同研究により探査フィ−ルドの提供のみならず,調査研究を共同して実施する必要がある。このため,(財)電力中央研究所とは,高温岩体発電のための亀裂面の評価に関する研究を,石油資源開発(株)技術研究所とは石油強制回収法のモニタリング実験を共同で実施した。また,金属鉱業事業団からは,MT法による深部金鉱床の探査に関する研究を受託した。さらに,文部省の重点領域研究のグル−プ(代表者:奈良国立文化財研究所の西村 康室長)とも連携して,国際遺跡探査学会を結成し,全国に分布する遺跡を科学的な調査である物理探査学の立場から順次実施している。なお,九州大学が統合・移転を計画している福岡市西区の元岡・桑原地区の基礎地盤調査,地下水源調査,地下水の塩水化調査,遺跡探査などを物理探査研究室が中心となって行なっている。
