Oso Oil & Gas Properties LLC installed a system to gather and process coal mine gob gas in Carbon County, Utah near the city of Price. Coal mine gob gas is methane gas diluted with various contaminants from the mine air ventilation system. The gob gas comes from the long wall cave areas of the Aberdeen Tower Mine and is brought to the surface with vertical drill holes that have been installed by the mining company to ensure mine safety. Under an exclusive agreement with Andalex Resources, Inc., the mining company that owns the Tower Mine, and the mineral estate owners, Oso collects the gob gas at the mine's vent wells. Oso compresses the gas and removes a small amount of hydrogen sulfide then transports the remaining gas five miles to a facility where oxygen and nitrogen are removed. Newpoint Gas Services, Inc. provided on oxygen removal system based on a catalytic combustion process. This oxygen removal process allows the gathering of the gob gas at a vacuum allowing a maximum amount of gas to be recovered. The resulting gas is then transported to the Pioneer Castle Gate Field processing plant where Oso and Pioneer gas is commingled and carbon dioxide and water is removed. The combined streams are then sold to Questar at the Whitmore Park interconnect approximately twelve miles from the Castle Gate Field. This project makes economic and environmental sense by allowing the recovery of a valuable gas stream that would otherwise be vented into the atmosphere.
