Profile
The main target of my research is "Utilization of geothermal energy". For this target, I research some geothermal field by mainly geophysical methods and evaluate the geothermal fluid flow of the field by some numerical model. Now I am conducting three joint researches with other organizations. And I was a member of some committees of New Energy and Industrial Technology Development Organization (NEDO). I have two lectures in English for foreign students.

    Egypt's current power generation capacity relies primarily on oil and natural gas. The Egyptian government's strategic objective of alternative energy source development is under severe strain due to the country's growing energy needs. Successive Egyptian governments have prioritized increasing renewable energy production as part of the country's overall energy output, with geothermal energy included as one of the new sources in Egypt's renewable energy program. Previous studies have highlighted the suitability of areas around the Red Sea and the Gulf of Suez for geothermal energy exploration; among these, the Hurghada and El Gouna area, located south of the Gulf of Suez at the Sinai Peninsula's triple junction with Africa and Arabia, is considered the most promising geothermal resource region. This study's main objective is to develop conceptual and numerical models of the Hurghada–El Gouna geothermal area based on temperature data obtained from deep onshore and offshore oil and gas wells, in addition to existing geological and structural information. Our numerical simulations reveal the presence of geothermal resources in the area, which are attributed to high, fault-controlled heat flow and deep subsurface water circulation. The rate of motion of water increases as it moves vertically through the fractures. After analyzing the simulation results, we assessed the feasibility of geothermal energy generation. Our findings indicate that the studied region has the potential to produce approximately 75 MW of electricity over a 25-year lifespan and 37.5 MW over a 50-year lifespan.

    In an effort to reveal the subsurface hydraulic changes in fractures by seismic monitoring, aperture-related velocity changes need to be investigated. We developed a numerical approach for calculating changes in elastic wave velocity with fracture aperture opening by determining the internal energy of a digitized fracture model based on natural rough surfaces. The simulated local elastic energy revealed that the interaction energy converged within 1.5 mm of the mean fracture position, and was insignificant unless the fractures intersected. This energetic approach clarified the aperture-velocity relationship and reproduced the experimental results. Further calculations using digital fractures with various sizes and densities demonstrated that the velocity can be accounted for by the superposition of a linear function of fracture density and quadratic function of aperture, and is insensitive to the fracture size. Although the relationship between fracture permeability and elastic wave velocity (i.e., the k-V relationship) depends on the fracture density, the offset-normalized k-V relationship shows clear linearity with the fracture density. The proposed k-V relationship as a function of the aperture and fracture density indicates that laboratory-scale fracture properties of a single fracture can be applied to multiple fractures on a larger scale. Our findings can be used to interpret temporal changes in seismic observations and to monitor fluid flow in fractures.
