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.

An active diapir forcefully intrudes its overburden, driven by diapir pressure that overcomes the resistance of the overburden strength. Possible causes of the driving pressure are differential loading of the source layer and a density contrast with the overburden.

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

Lake Meredith, which supplies water for domestic use to all major Texas cities on the Southern High Plains, exceeds State of Texas limits for chloride and sulfate content.

Low recovery efficiencies of sandstone reservoirs in the Jackson-Yegua Barrier/ Strandplain Sandstone play mark it as a large hydrocarbon resource target for advanced recovery techniques.

This report summarizes geologic, engineering, and production information on 24 low-permeability, gas-bearing sandstone reservoirs in 13 basins in the United States.
