South Hallettsville Field, discovered in 1976, produces gas and condensate from a lower Wilcox Clastic Wedge. The discovery well, General Crude Oil 1 Anderson, was drilled on an Edwards seismic closure, encountered high pressure gas sands in the lower Wilcox, blew out, and was abandoned. The replacement well had potential of 23,926 mcfd flowing and 38.7 bbl condensate per mmcf of gas through perforations from 9909 to 10,011 ft (2973 to 3003 m). Within 2 yr, this well had produced 2.1 billion cu ft of gas and 74,543 bbl of condensate. The wedge has a sandstone shale ratio of 20%. Reservoir sands are medium to very fine grained, individual or stacked, and several inches to 25 ft (7.5 m) thick. The sand is 40 to 70% quartz with 10 to 35% feldspar and lithic fragments. The matrix is kaolinite, chlorite, illite, and illite/smectite with minor carbonate cement. Reservoir sands have porosities of 18 to 24.7% and permeabilities of 0.5 to 83 md.
