Coalbed methane production has been established in the Sand Wash Basin. Large coal resources, gas shows during drilling of coal beds, and high gas contents in some coals triggered initial development along the basin margins. Results to date have been disappointing.
Geologic and engineering studies were conducted within fluvial/deltaic strata of a mature South Texas field to determine the impact of reservoir compartmentalization on secondary gas recovery. Stratton is one of several mature South Texas fields containing fluvial and deltaic gas reservoirs.
This report documents research done on the mature and prolific McAllen Ranch gas field in South Texas, as part of the Secondary Gas Recovery (SGR) project funded by the Gas Research Institute, U.S.
