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.

There was a consensus that technology has in the past reduced, and will continue in the future to reduce, exploration and production costs. In the United States, for example, rigorous application of technology has resulted in the last decade or so in essentially flat supply cost projections.

Dipmeter analyses performed within McAllen Ranch field, Hidalgo County, South Texas, proved useful in finding reserves of natural gas.
