Ten natural gas companies have funded the Institute of Gas Technology (IGT) development of a laboratory facility for fluid and core analyses at temperatures and pressures characteristic of geopressured aquifers. The facility has been designed and constructed to measure the following parameters at pressures up to 20,000 psi and temperatures 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 temperatures; dependence of relative permeabilities to gas and to water upon the water saturation of pores, pressure, and temperature. Brine pumped through the core can be either gas-free or from a reservoir of brine 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. All components contacted by high-pressure, high-temperature brine are fabricated from Hastelloy C-276, Elgaloy, or Inconel 625 to avoid corrosion. The temperatures, pressures, differential pressure, and flow rates are controlled and/or recorded by a digital microcomputer/microprocessor. Operation will be controlled from a separate room and programmed; hands-off operation will be the normal mode of operation. The facility has been constructed and is now being tested.Following performance testing with Berea sandstone, initial emphasis will be upon studies of brine and available core from DOE's Pleasant Bayou No. 1 and No. 2 wells.
