Geopressured aquifer simulator

OSTI ID:6015207
Because previous devices for testing core samples of geopressured rock have failed to measure key properties under in situ conditions, IGT designed and built a laboratory facility for fluid and core analyses at temperatures and pressures characteristic of geopressured aquifers. The facility measures the following parameters at pressures up to 20,000 psi and temperatures up to 450/sup 0/F: solubility of methane in brines from actual geopressured aquifers, dependence of compression and compaction reservoir drive upon pressure, dependence of permeability upon reservoir pressure and temperature, and dependence of relative permeabilities on the water saturation of pores, pressure, and temperature. Brine pumped through the core can be either gas-free or with gas in solution. The facility is modular in design, with major components (including the reservoir of gas-saturated brine, high-pressure positive-displacement pumps, and the core holder) housed in a large oven. A digital microcomputer/microprocessor controls and records the temperatures, pressures, differential pressure, and flow rates.
