Gordon Creek Field, Carbon County Utah: Methane, CO2, and Potential Carbon Storage Unit
Craig Morgan, Stephanie Carney, and Peter Nelsen
More than 4 BCF of methane gas has been produced from the Cretaceous Ferron Sandstone at Gordon Creek field in central Utah. Significant volumes of CO2 have been tested from the Jurassic Navajo Sandstone, the Sinbad Member of the Triassic Moenkopi Formation, and the Permian White Rim Sandstone. Gordon Creek field lies midway between Clear Creek field (115 BCFG), which produces from sandstones in the Ferron, and Drunkards Wash field (851 BCFG), which produces from the coals in the Ferron. The Ferron reservoir is underdeveloped at Gordon Creek and has the potential for many new wells. The Emery Sandstone and Blue Gate Shale Members of the Cretaceous Mancos Shale are exposed along the crest of the Gordon Creek anticline, which has about 300 feet of four-way closure at the Ferron horizon. The structure is about 9 miles by 5 miles on the surface. A basal detachment in the evaporite section of the Jurassic Arapien Shale often results in a structural discordance between Cretaceous and deeper horizons in this region. At Gordon Creek field only three wells have penetrated the Navajo and deeper formations. More than 8 MMCFGPD of 98% CO2 has been tested from both the 100-foot-thick Sinbad Limestone and 600-foot-thick White Rim Sandstone. CO2 has been tested from the Navajo Sandstone as well. Based on old geophysical well logs the Sinbad and White Rim have low porosity (5%), but may be extensively fractured based on the high flow rates. The White Rim is a thick eolian deposit that has the potential for very large CO2 reserves. Gordon Creek field along with other fields in the area, such as Farnham Dome, could be a CO2 source for EOR in the Uinta Basin. The field was characterized by the SWP as a potential CO2 storage site to reduce greenhouse emissions in the future.
