  <dc:description>&lt;p&gt;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.&lt;/p&gt;&lt;p&gt;During the course of the 1975 drilling methane (CH&lt;sub&gt;4&lt;/sub&gt;) 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.&lt;/p&gt;&lt;p&gt;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.&lt;/p&gt;</dc:description>
