With Colorado Geological Survey. Geologic and Hydrologic Controls on Coalbed Methane: Sand Wash Basin, Colorado and Wyoming With Colorado Geological Survey. Geologic and Hydrologic Controls on Coalbed Methane: Sand Wash Basin, Colorado and Wyoming 1994

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.

Quantifying secondary gas resources in fluvial/deltaic reservoirs: a case history from Stratton field, south Texas Quantifying secondary gas resources in fluvial/deltaic reservoirs: a case history from Stratton field, south Texas 1994

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.

Impacts of Technology on the Global Gas Resource Base: Proceedings of the Global Gas Resources Workshop Impacts of Technology on the Global Gas Resource Base: Proceedings of the Global Gas Resources Workshop 1994

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.

Use of dipmeters in stratigraphic and depositional interpretation of natural gas reservoirs of the Oligocene Vicksburg Formation: an example from McAllen Ranch field, Hidalgo County, Texas Use of dipmeters in stratigraphic and depositional interpretation of natural gas reservoirs of the Oligocene Vicksburg Formation: an example from McAllen Ranch field, Hidalgo County, Texas 1994

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