Acoustic and electrical properties of Mexican geothermal rock samples

PDF Version Also Available for Download.

Description

Acoustic compressional and shear-wave velocities have been measured on a suite of ten sandstone samples obtained from wells in the Cerro Prieto geothermal field and on two rock samples from other Mexican geothermal fields. The samples were tested in both their dry and fully brine-saturated states at uniaxial stresses to 15 MPa. Electrical resistivities and associated phase angles have been measured on the same core samples as a function of frequency in the range 10 Hz to 10/sup 5/ Hz under drained conditions at hydrostatic confining stresses to 10 MPa. The electrical properties were measured on samples tested in their ... continued below

The electrical properties were measured on samples tested in their fully saturated state, using brines of two different concentrations.
