Abstract
The Geological Survey conducted a seven-hole core-drilling program in the Recluse Geologic Analysis Area, northern Campbell County, Wyoming, in 1975. The purpose was to acquire rock and coal samples to further evaluate the surface-minable coals of this area. In 1976 the Bureau of Land Management defined a portion of this area as an Energy Mineral Resource Inventory and Analysis Program reclamation study area and drilled an additional eight core holes.
During the course of the 1975 drilling methane (CH4) emissions were detected in all holes. The quantities ranged from very small amounts of methane (+0.1 percent) in the return drilling air to major flows estimated to be as much as 1,000,000 cubic feet per day.
Methane in the return drilling air or fluid is a serious safety hazard to personnel and equipment. On the other hand, the methane might have economic value.
