(Copublished with Colorado Geological Survey). Coalbed Methane in the Upper Cretaceous Fruitland Formation, San Juan Basin, New Mexico and Colorado (Copublished with Colorado Geological Survey). Coalbed Methane in the Upper Cretaceous Fruitland Formation, San Juan Basin, New Mexico and Colorado 1994

Coalbed methane is playing an increasingly important role in meeting the energy needs of the United States. According to one estimate, this unconventional gas may supply 4-5% of the domestic natural gas in 1994.

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.

Gas reservoir quality variations and implications for resource development, Frio Formation, south Texas: examples from Seeligson and Stratton fields Gas reservoir quality variations and implications for resource development, Frio Formation, south Texas: examples from Seeligson and Stratton fields 1993

Discovery of volcanic glass detritus in fluvial deposits of the middle Frio Formation (Seeligson and Stratton fields) of South Texas has resulted in a new classification of reservoir types (type I and type II) within this formation.

Geothermal and heavy-oil resources in Texas: direct use of geothermal fluids to enhance recovery of heavy oil Geothermal and heavy-oil resources in Texas: direct use of geothermal fluids to enhance recovery of heavy oil 1993

In a five-county area of South Texas, geopressured-geothermal reservoirs in the Paleocene-Eocene Wilcox Group lie below medium- to heavy-oil reservoirs in the Eocene Jackson Group. This fortuitous association suggests the use of geothermal fluids for thermally enhanced oil recovery (TEOR).
