November 10, 2014 Source: U.S. Energy Information Administration, EIA uses two differing methods to determine production from major and minor oil and natural gas plays onshore in the United States. One method takes a geographic approach, focusing on surface-level analysis, and the other method uses a geologic approach, focusing on formation-level details. The differences between […]
