Abstract

A high-pressure high-temperature cell has been constructed and used to determine the temperature dependence of the electrical conductivity of various geological materials at a frequency of 60 Hz. Test conditions in the cell approximate an in situ environment by means of a variable uniaxial confining pressure and a separately variable pore pressure. A wide array of constituents of typical oil bearing formations have been examined at temperatures up to 240°C
