Electrical Resistivity of Strained Rocks (4)

Resistivity of Rocks

A brief summary of the importance of the electrical resistivity of rocks in geothermal exploration is given as well as some of its is main relationships with some of the characteristics of geothermal reservoirs. Special emphasis is on the resistivity of rocks in high temperature geothermal fields where the dominant factor is the hydrothermal mineral alteration and how it relates to temperature....

the study of effect of confining pressure on electrical resistivity of hydrocarbon reservoirs rocks

the electrical resistivity of hydrocarbon reservoir rocks is an important parameters in the calculation of water and oil saturation percent in both carbonate and sandstone reservoir rocks.in this regard, most studies have concentrated on the confining  pressure on cementation factor and electrical resistivity in sandstone reservoir rocks. in this study the effect of confining pressure on cement...

Modeling Fluid Flow and Electrical Resistivity in Fractured Geothermal Reservoir Rocks

Phase change of pore fluid (boiling/condensing) in rock cores under conditions representative of geothermal reservoirs results in alterations of the electrical resistivity of the samples. In fractured samples, phase change can result in resistivity changes that are more than an order of magnitude greater than those measured in intact samples. These results suggest that electrical resistivity mo...

Growth, surface morphology, and electrical resistivity of fully strained substoichiometric epitaxial TiNx „0.67ÏxË1.0... layers on MgO„001..

We have grown single-crystal NaCl-structure d-TiNx layers with x ranging from 0.67 to 1.00 on MgO~001! at 700 °C by ultra-high-vacuum reactive magnetron sputtering of Ti in mixed Ar/N2 discharges in order to investigate microstructural evolution and the physical properties of TiNx as a function of the N vacancy concentration. High-resolution x-ray diffraction and transmission electron microscop...
