Triaxial compression tests were run at room temperature to determine failure characteristics of rocks extracted from the geopressured-geothermal reservoir underlying Brazoria County. Effects of both confining and pore fluid pressure were considered. Like all other rocks, ultimate strength was found to increase with increase in effective confining pressure. Partial ductile behavior was observed at pressures above 5000 psi. In general rocks from this reservoir were found to be considerably weaker than corresponding well compacted sandstones.
