For the l a s t several years, the University of Texas a t Austin (UTA) and, more For the last several years, the University of Texas at Austin (UTA) and, more recently, Louisiana State University (LSU) have analyzed the geopressured tertiary sandstones along the Texas Gulf Coast and the Louisiana Gulf Coast with the objective of locating prospective reservoirs from which geothermal energy could be recovered. Of the "geothermal fairways" (areas with thick sandstone bodies and estimated temperatures in excess of 300'F) in Texas, the Brazoria Fairway in Brazoria County appears most promising and the Austin Bayou Prospect has been developed with in this fairway. The first well drilled at the Austin Bayou Prospect (DOE Pleasant Bayou No. 1, drilled in 1978) is being used for reinjection since well completion problems precluded its use for geopressured reservoir testing. A second well (DOE Pleasant Bayou No. 2) was drilled in 1979 in the immediate vicinity of the first to obtain the transient flow data needed to evaluate the geopressured reservoir. Preliminary short term production ana buildup tests of the Pleasant Bayou No. 2 well were conducted during the second half of 1979. A series of five pressure drawdown (production times ranging from 13 minutes to 10.5 days) and buildup tests were perforrned with flow rates up to about 20,000 bbl/day in an effort to evaluate formation parameters for the geopressured sand perforated at 14,644 feet to 14,704 feet (net sand thickness 60 feet ) . The relevant flow and pressure data are given in a report by Clark [l].
