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.

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.].

Geothermal wells at Sumikawa are divided into two groups: one produces fluids of vapor dominated and another of water dominated. This is probably because of the presence of vapor-dominated zone formed partly in the reservoir of water single-phase. A numerical three dimensional reservoir model was developed for simulations both natural state and history matching of production and reinjection for about 25 years since the start of the power generation at Sumikawa in 1995. A relative permeability curve of Corey type was employed with residual saturations of 0.23 and 0.16 for water and steam, respectively. Simulation results of specific enthalpy history of produced fluids at Wells SA-1 and SA-3 showed good agreement with measured values in the range of 1500-2500 kJ/kg. A horizontal narrow layer of high permeability in the model was assigned in the area connecting high temperature zone in the south and the grid where Well SA-1 presents for describing high specific enthalpy values and its gradual decrease with time

Geothermal production wells sometimes show oscillations of wellhead pressure and flow rate when completed with multiple feed zones. This instability of the production causes a lack of steam supply and unstable turbine inlet pressure at a power plant. In the worst-case, steam production of the well may cease. However, its mechanism has not been well understood. In this study, we developed a numerical model of transient steam-water two-phase flow in a geothermal production well. This wellbore model is coupled with a reservoir model so we can treat flow rate change with time from the reservoir into the wellbore and deal with a well with multiple feed zones. We use a homogeneous flow model of steam-water mixture in a wellbore. Thus, we developed a numerical simulator coupled with a modified semi-implicit method, and succeeded in suppressing a generation of mass error when phase change occurs. The simulation results show that oscillation of flow rate in a wellbore occurs as temperature difference of the fluids between the feed zones becomes large. The results also show that the oscillation is generated by interactions among pressure, pressure drop, and specific enthalpy of fluids in a wellbore.

Deliverability of geothermal production wells is evaluated by measuring wellhead pressure versus mass flow rate at several wellhead pressures. Controlling a main valve of the well results in the changes in wellhead pressure and mass flow rate. However, duration required for these variables to stabilize depends on flowing behavior of steam-water two-phase fluid in the wellbore. Fluid stabilization seems to be an important parameter, mainly for short period of measurement. In addition, the manner of controlling valve operation whether it starts from the well in full-closed condition or in full-opened condition seems to affect this flow stabilization. Thus, the experiment was carried out for a production well 2H-21 at Hatchobaru geothermal field, Japan to verify these hypotheses. The measurement apparatus consisted of pressure sensors, water level sensor and a PC to store the measured data. The data were recorded every second for the pressures at upstream of the orifices, the pressure drops at the orifices, the pressures at the separators, and the water level at weir box. The degree of valve opening was changed three times during the measurement. Then, the duration of respective wellhead valve operation for controlling flow rate affecting the flow stabilization in wellbore was observed. It was found that quick valve operation caused longer period for stabilization and produced impulse response of flow rate soon after the valve operation stopped. The fluid flow required about 7 min to stabilize for closing valve operation whereas it needed longer than 20 min to reach the stable condition for opening valve operation. After changing the wellhead pressure, the steam flow rate stabilized quickly while the water flow rate showed a gradual change.

We analyzed tracer tests in the Ogiri geothermal field, which was conducted in 2008 and 2011, respectively. The test results were analyzed with the multi-flowpath model, then interpreted together with hydrological features of the field determined from geological settings and geophysical surveys. The results indicate the presence of two flow path for reinjected water flowing to the production zone in the Ginyu fault. A part of the reinjected water flows into the main production zone of the Ginyu fault directly through this fault from the west. The water also flows the Ogiri deep faults zone located to the south of the Ginyu fault, then flows into the Ginyu fault from the east which takes longer time to reach the production zone.

Fundamental properties of substorm time energetic electrons in the inner magnetosphere Reviewed

Y. Ebihara, Toshiaki Tanaka

Journal of Geophysical Research 118 ( 4 ) 1589 - 1603 2013.1

　More details

Language：English

We studied fundamental properties of spatial-temporal evolution of energetic electrons trapped in the inner magnetosphere (L ≤ 7.4) during an isolated substorm by using a four-dimensional drift kinetic simulation under the time-dependent electric and magnetic fields provided by a global magnetohydrodynamics (MHD) simulation. When the interplanetary magnetic field turns southward, both the potential and induction electric fields start to increase in the inner magnetosphere, resulting in a gradual injection of low-energy electrons (≤51.9 keV) and deceleration of high-energy electrons (≥114 keV). The deceleration of high-energy electrons results in a decrease in the phase space density of the high-energy electrons during the growth phase. After a while, an abrupt transition of phase state (a substorm onset) occurs in the magnetosphere, which triggers abrupt changes in the magnetosphere and ionosphere. The AL index decreases rapidly, and magnetic field lines become dipole-like. The dipolarization does not proceed smoothly in the inner magnetosphere because of significant force imbalance between the J × B force and the grad P force. As a consequence, the electric field oscillates with a period of 2-3 min, resulting in multiple injections of the low-energy electrons. The low- and high-energy electrons are accelerated under the strong influence of the drift betatron and gyro betatron, so that the acceleration process is essentially nonlinear. Our simulation results suggest that the force-induced processes play an essential role in the substorm-associated redistribution of energetic particles in the inner magnetosphere. Key Points Two types of substorm-electric fields are identified in the inner magnetosphere.Electric field oscillation is generated by force imbalance near substorm onsetRedistribution of energetic electrons comes from force imbalance and ionosphere

Language：English

[1] Response of the magnetosphere-ionosphere system to a negative impulse of the solar wind dynamic pressure (the negative SI) is studied again with foci of the following three points; multiple convection oscillations, mirror-image relationship between the negative and positive SIs, and appearance of the overshielding potential. When the negative impulse impinges on the magnetopause, the Region 1 (R1)-type field-aligned current (FAC) and R2-type FAC appears alternatively in the dayside polar ionosphere (∼70°, ∼10 hLT and 14 hLT). These ionospheric current systems shift nightward and poleward. This alternative appearance of FACs invokes positive and negative ionospheric potential patterns switching alternatively. It is revealed that the negative SI is accompanied with multiple convection oscillations repeating more than the positive SI. We also notice that the magnetospheric current system producing the preliminary impulse (PI) of the intensive negative SI is a mirror-image of that of the positive SI. The multiple convection oscillations and the mirror-image relationship were not discussed by Fujita et al. (2004) who studied a moderate-amplitude negative SI. In addition, the R2-type FACs induced by the negative and positive SIs tend to yield the overshielding electric potential in the ionosphere. The shielding potential invoked by the SIs has shorter duration than that for the northward turn of the interplanetary magnetic field. The duration is longer for the negative SI than for the positive SI.

We reproduce a magnetospheric reconfiguration under southward interplanetary magnetic field (IMF) conditions using numerical magnetohydrodynamic simulations. To investigate the relative displacements of the geomagnetic conjugate points, we trace both footprints of the geomagnetic field lines during the magnetospheric reconfiguration under positive and negative IMF B_y conditions. Several substormlike features, namely, the formation of a near-Earth neutral line, a fast earthward flow, and tailward releases of the plasmoid, occur about 1 h after a southward turning of the IMF. The surveyed field line traced from the near-Earth magnetotail was strongly distorted duskward in the north and south after the substorm onset for positive and negative IMF B_y, respectively. The maximum of the relative longitudinal displacement of both footprints is 4.5 and 5.5 h in magnetic local time for positive and negative IMF B_y, respectively. While observational studies have indicated that the IMF orientation is the main factor controlling the relative displacement of the conjugate points, the present simulation-based study with a constant IMF orientation shows for the first time that the combined effects of plasma pressure, magnetic field intensity, and the field-aligned current density distribution along the field line are likely to be major factors controlling the relative displacement of conjugate points.

The work involved in identifying geothermal fields can be simplified by means of a Geographical Information System (GIS), a decision-making tool used to determine the spatial association between exploration and environmental thematic maps. This methodology has been applied to part of the Sabalan geothermal field in northwestern Iran, and to the siting of exploration wells. The datasets used in the analyses consist of geological, geochemical and geophysical information. Boolean and Index Overlay knowledge-driven models were developed for site selection; the findings from these two models correlated well with the exploration data modeling. The results of the Index Overlay model were combined with those of an environmental suitability analysis for final selection of well sites. The results of exploration and environmental data modeling were combined to select and prioritize the sites of three exploratory wells in the study area.

In this study, a Geographic Information System (GIS) is used as a decision-making tool to target potential regional-scale geothermal resources in the Akita and Iwate prefectures of northern Japan. The aims of the study are to determine the relationships between geothermal wells and geological, geochemical, and thermal data layers within the GIS and to use these relationships to identify promising areas for geothermal exploration. We calculated the distances from existing productive geothermal wells to Quaternary volcanic rocks, calderas and craters, faults, hot springs, fumaroles, and hydrothermal alteration zones. The dominant distances were then defined for each evidence layer. We used ArcMap to develop a GIS Model for Geothermal Resource Exploration (GM-GRE) consisting of geoprocessing tools and a modelbuilder. Areas of geothermal potential were defined and prioritized by assigning a weighted overlying selection query for geological, geochemical, and thermal data layers. The result shows that 97% of currently productive geothermal wells in Akita and Iwate prefectures are located within the first priority zone selected by the GM-GRE.

Substorm onset caused by the two state transition of the magnetosphere

Toshiaki Tanaka

Multiscale Coupling of Sun-Earth Processes 217 - 233 2005.12

　More details

Language：English

The substorm process is simulated by resistive magnetohydrodynamic (MHD) equations. Starting from a stationary solution under a northward interplanetary magnetic field (IMF) condition with non-zero IMF, B_y, changes in magnetospheric convection following the southward turning of the IMF are investigated. The simulation results first show the progress of plasma sheet thinning in the tail. This thinning is caused by the drain of closed flux from the near-earth plasma sheet coupled with the enhanced ionospheric convection. In this stage, the flux transported from the near-earth tail to the dayside cannot be replaced by the flux from the midtail because the reclosure process of open field lines in the midtail plasma sheet is still slow because of the control by the remnant of northward IMF. The substorm onset occurs as an abrupt shift of the pressure peak in the plasma sheet from -12 Re to -8 Re and an intrusion of convection flow into the inner magnetosphere. After the onset, the simulation results reproduce both the dipolarization in the near-earth tail and the formation of near-earth neutral line (NENL) at the midtail, together with plasma injection into the inner magnetosphere and an enhancement of the nightside field-aligned current (FAC). During the dipolarization process, the static magnetospheric force balance changes from the z-direction-dominated state to the x-direction-dominated state. Thus, the dipolarization is not a mere pile up of the flux ejected from the NENL. The pressure distribution in the near-earth plasma sheet changes so, as to self adjust the restored magnetic tension associated with the establishment of force balance in the x direction. The direct cause of the onset is the state (phase-space) transition of the convection system from a thinned state to a dipolarized state.

For analysis of the hydrological connectivity between production and reinjection wells in the Kakkonda geothermal field, tracer tests were performed in 2002. In the tracer test, two different types of tracer were injected at respective reinjection well-116 and 136, and tracer return was examined by repeated sampling of water at 26 production wells. The results were analyzed with the multi-flowpath model to evaluate the magnitude of hydrological connectivity among the wells used in the tracer test, and to understand the flow behavior of reinjected water. Satisfactory results were obtained with a two-flowpath model for most production wells. Comparison of fluid velocities in each flowpath and the directions between the main feed points of production and reinjection wells indicated a possibility that some production wells are hydrologicaly connected to each other through the same fracture system. Tracer return are divided into two groups on the basis of mean-arrival-time, and amount of reinjected water return to production zone is appreciable for those with longer arrival time.

Potassium bromide (KBr) and potassium iodide (KI) tracers were individually injected into two reinjection wells at Sumikawa: KI with steam condensate into one well and KBr with separated waste water at high temperature (140 °C), into another well 1000 m away from the KI well. The tracer concentrations were then analyzed in all production wells for 16 months. The iodine tracer was first detected in two wells (wells S-4 and SB-1) within 1000 m of the injection well within 47 h and in other wells (with the exception of well SC-2) up to 1500 m away within 9 days after injection. Before background correction as mentioned below, most of the injected iodine tracer was recovered from the production wells within 6 months. The bromine tracer was also observed first in well S-4 within 5 days and in other wells within 1 month, except for well SC-2. These observations show that vapor condensate quickly returns into wells S-4 and SB-1 compared to geothermal fluids. These results are consistent with the previous calculations examined through a box model using chlorine concentrations and hydrogen isotope ratios of fluids from production wells. The results of the present tracer tests were examined using a multi-path model. First, the background concentrations of both tracers were recalculated because the total recovered amounts of I and Br exceed the amounts that were originally injected. The variations of the tracer concentrations were then fitted by setting two or three paths between the injection and production wells. Our calculations show that the recovered fractions of I and Br are 36 and 40%, respectively, and the velocities of fluids in the reservoir are estimated to be 0.4 to 14.9 m/h in the case of both tracers.

The effects of initial water saturation on well characteristics in two-phase geothermal reservoirs were evaluated. A vertical wellbore model of uniform diameter coupled with a radial horizontal flow in a reservoir of uniform thickness was employed. The momentum equation for two-phase flow in a wellbore was numerically evaluated with a method introduced by Orkiszewski. The energy equation in the wellbore was assumed to be isenthalpic. Mass flow rate and pressure at a feed zone of the well were calculated using a steady radial flow in a reservoir. The numerical calculation showed that the lower initial water saturation in the two-phase reservoir leads to less total flow rate at a given wellhead pressure. However, the decrease in the initial water saturation results in an increase in the maximum discharge pressure. The initial water saturation does not affect the steam flow rate significantly for low wellhead pressure.

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.

The discharge rate of HC1 gas from the fumarolic area at Kuju volcano had been estimated on the basis of distributions of Cl^- concentration in rainwater and precipitation. The rain collectors of open type were set at eleven locations. within 7 km from the main fumarolic area. The rainwater was collected and then analyzed for chemical, compositions at intervals of two weeks from March to December during 1993-1997. The HC1 discharge rate in 1995 was stable at about 2.0 t/d until, early in July, and then increased abruptly to 6.7 t/d late in July. This increase of the HC1 discharge rate can be a precursor of the phreatic eruption on 11 October 1995. The maximum discharge rates were observed from April to May in 1996. In this period, both seismic activities below the fumarolic area and the energy discharge from the new craters increased. The discharge rate of HC1 decreased from July. 1996 with some fluctuations.

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.

A three dimensional numerical reservoir model of the Dieng geothermal field was developed for the pre-exploitation stage using the TOUGH2 simulator with a forward analysis method. The model was verified by matching temperature profiles of exploration wells. The numerical model in the natural state simulation was able to successfully reproduce initial temperatures from 11 wells.

Numerical simulations of the Ogiri geothermal reservoir were conducted using a fractured reservoir model with particular focus on the periods of power plant maintenance when all production and reinjection wells are shut-in for a few weeks. The results show that the steam-water two-phase zone in the shallow reservoir shrinks somewhat and the single-phase water zone expands.

Oscillations in wellhead pressure are sometimes observed in production wells with multiple feedzones. This instability affects stable steam production, and in extreme cases may cause steam production from the well to cease altogether. In this study, we developed a coupled model of transient wellbore and reservoir flows with two well feedzones. Then, numerical simulations were carried out to evaluate the effects of reservoir temperature on the flow characteristics of wells with multiple feedzones. These simulation results show that the cyclic changes in wellhead pressure are caused by temporal changes in the flash point depth within the wellbore.

We developed a vertical two-dimensional porous media for modeling a fault system, and conducted tracer experiments using two kinds of dye as a tracer material. In addition, in order to simultaneously measure concentrations of these dyes in the produced fluid of simulated production well, we developed optical tracer concentration sensors using an absorption spectrophotometry method. Results showed that concentrations of dyes were measured with an acceptable accuracy for the mixed solution of the tracers as it reached the production well.

A three-dimensional numerical reservoir modeling of the Kotamobagu hydrothermal system was carried out. A natural state model of Kotamobagu was obtained by conducting simulations by changing parameter values of permeability, heat and mass recharges. The results of simulation were calibrated to temperature data from hot spring of Liberia and Bongkudai villages. The developed model confirmed that mass flows upward from the bottom layer to the surface, then travels laterally. The dominant mass flows through faults running northeast and to southwest. The mass from the bottom of Mt. Muayat flows to the southwest through the andesitic lava and the pumice tuff layers. Further, at the surface of Liberia and Bongkudai area, 3kg/s of mass is being discharged to the hot spring, the portion of mass flows through the fault to the southwest and continues further to the west. In the southwest area, mainly in Bakan, there is no mass discharge corresponding to related modeling blocks. Simulation results implies that the source of heat and mass discharge at the Bakan hot spring is not derived from Mt. Muayat, but from some source below sedimentary formation.

Magnitude of return of reinjected water to production wells was evaluated by numerical simulations with TOUGH2 at the Ogiri geothermal field for 13 years operation. A function of specifying two kinds of fluid in TOUGH2 was used to distinguish reinjection water and deep recharge fluid. Production wells located relatively adjacent to reinjection zone showed high mass ratio of reinjected water to produced fluid.

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.

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.

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.

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.

An advanced geophysical technique for reservoir monitoring by electrical prospecting has been developed by the joint research works of Kyushu University and JAPEX on the EOR Project in Canada. The method has been applied to monitor fluid-flow behaviors during steam injection operations. With an automatic recording system controlled by a personal computer, charged potentials and spontaneous potentials can be simultaneously measured as a function of time at multiple stations surrounding an operating borehole. Fluid-flow behavior in the subsurface was visualized as a function of time by means of contour maps of the residual potential and the relative changes of apparent resistivity during the thermally enhanced oil recovery process at Hangingstone test site in Fort McMurray, Alberta, Canada.

Development of compact exploration equipments for MT method for predictive detection of landslide disasters

Grant number：19K04950 2019 - 2023

Japan Society for the Promotion of Science Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C)

　 More details

Authorship：Principal investigator Grant type：Scientific research funding

In steep slope areas, the risk of landslides increases when groundwater levels rise rapidly due to heavy rainfall. To detect rising groundwater levels at the ground surface, a compact MT method exploration equipment was developed, focusing on the change in the resistivity of the ground. The exploration equipment was emphasized for its portability and light weight. A prototype of the equipment was developed and its basic functions were tested in the laboratory and in the field. In the MT method, which measures electric and magnetic fields, noise from power lines can be an obstacle to measurement in both urban and mountainous areas. Therefore, based on the results of noise evaluation, an appropriate noise reduction circuit was added to the exploration equipment. As a result, it was confirmed that the electric and magnetic fields can be accurately measured.

地雷除去や遺跡発掘等、地下の埋設物探査は地中レーダー探査法が用いられているが、地質スケールの小さい対象物を高精度に検知できないなどの問題がある。本研究開発では直流電気探査の原理を利用して従来の地中レーダ探査に比べ、安全かつ高精度の探査を可能とする携帯型の探査計を実用化する。本電気探査計は、ダム等の漏水検査、産業廃棄物の土壌汚染調査など社会基盤分野における工学的診断・安全面における貢献も期待できる。
