Dipmeter analyses performed within McAllen Ranch field, Hidalgo County, South Texas, proved useful in finding reserves of natural gas. McAllen Ranch field produces from the Oligocene Vicksburg Formation on the downthrown, east block of a listric growth fault that merges with a flatlying glide plane beneath the field. This study concentrated on the Vicksburg S reservoir in a 5-mi2 (13-km2) area of the field (the B area), where a dense array of 15 dipmeter logs and a three-dimensional seismic survey were available.

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. The relatively stable supply costs are due to technology and its impact in reducing production costs (William L. Fisher, "The U.S. Experience in Natural Gas: Revitalization of a Resource Base Thought Exhausted, this volume).
