USGS oil and gas assessments are for technically recoverable resources, meaning they can be produced using today’s technology and standard industry practices. However, our assessments do not look at what infrastructure would be required to produce these resources, nor does it look at whether it would be profitable to produce them.
In addition, USGS assessments are for undiscovered resources, which are estimated to exist based on geologic knowledge and theory. Before they can be produced, these resources must be proven to exist.
