2020, GeothermicsCitation Excerpt :Current geophysical methods used to gain knowledge about geothermal fields include electrical resistivity tomography, electromagnetic methods, tracer tests, self-potential methods, gravity studies and seismic methods. Electrical resistivity methods have proven useful for studying geothermal fields due to the high dependence of electrical resistivity on physical parameters like fluid saturation, porosity, temperature, mineral alteration and pore fluid salinity (Arnason et al., 2000; Santos et al., 1997; Storz et al., 2000; William et al., 1976). The influence of clay minerals on resistivity is greatly dependent on the type of minerals and the pore fluid salinity.
Geophysical investigation in the Northwestern part of the Gulf of Suez, Egypt
2017, Egyptian Journal of PetroleumCitation Excerpt :The results of the drilling report of the borehole indicate that the subsurface consists of Quaternary deposits of sand and gravel of high resistivity that overlay a fresh water aquifer, then salt and brackish water until depth about 100 m. Fresh and salt water aquifer overlay limestone layers until depth of 220 m and exhibits resistivity values about 20 Ohm m (Fig. 5). The 3-D inversion code used in this work was developed using the finite-element approach for forward calculations and a smoothness-constrained least-squares algorithm for inversion [22,23,15]. The program uses an irregular mesh constructed for each VES site, taking into account sounding parameters (AB/2 spacing and azimuths of AB layout of VES arrangements).
A pilot magnetotelluric survey for geothermal exploration in Mae Chan region, northern Thailand
2015, GeothermicsCitation Excerpt :In the north, part of the weathered and fractured granite along with the sedimentary layer is interpreted to be filled with the hot fluid, which produces the low resistivity zones C1 and C2 (Fig. 5). As with other non-volcanic geothermal systems in granitic rocks (Gianelli et al., 1997; Harinarayana et al., 2006; Newman et al., 2008; Santos, 1997; Uchida et al., 2005), the heat source for the hot fluid in the Mae Chan region should come from the batholith granite R at great depth. When the rain water infiltrates into the ground, the ground water is heated by the hotter batholith resulting from the decay of radioactive elements of the minerals in the granite.
