A recent assessment discovered millions of barrels of oil and billions of cubic feet of natural gas resources in northwest Colorado and southwest Wyoming.
The United States Geological Survey announced the discovery of new resources in the Phosphoria Total Petroleum System, which has produced oil and gas since the 1920s. Since then, approximately 500 million barrels of oil and 2.5 trillion cubic feet of natural gas have been recovered from the system.
The discovery includes an estimated 3 million barrels of oil and 666 billion cubic feet of gas that are recoverable. Despite the survey’s findings, the USGS believes that the system may be nearing depletion.
“USGS energy assessments typically focus on undiscovered resources – areas where science tells us there may be a resource that industry hasn’t discovered yet. In this case, after 100 years of production, we estimate the Phosphoria Total Petroleum System has relatively little remaining oil and more than 600 billion cubic feet of gas,” said Sarah Ryker, acting director of the USGS.
