| Abstract | Scanning electron microscope examination has been done on pre-test and post-test specimens from experiments on core from the Cerro Prieto and East Mesa geothermal field at simulated in situ conditions of high temperature and pressure. The microscope observations are being done in conjunction with measurements of permeability and creep compaction to provide reservoir engineering data and developed constitutive models of subsidence prediction. Evidence for pressure solution is observable as dissolution at grain contacts and overgrowth of euhedral quartz on detrital grains. |
