Changing Perceptions Regarding the Size and Production Potential of Coalbed Methane Resources

摘要: currently an active play in a number of basins throughout the United States. Over past decade, gas industry’s pessimistic perceptions total in-place and recoverable coalbed methane resource base U.S. lower-48 states have been shown to wrong. The finding costs new reserves are now comparable or even lower than those conventional natural resources, favorable geologic settings reservoirs can also coproduce commercially significant quantities light oil. New reservoir property evaluation methods, improved drilling completion practices, enhanced recovery technologies enabling industry expand size economically base. rapid growth well completions production that occurred from 1988 1992 San Juan Black Warrior is being repeated today large, plays Powder River, Uinta, Raton, Central Appalachian basins. success these low-cost has sparked resurgence interest evaluating potential huge, as yet untapped, resources present This article highlights changed regarding this resource.
