USGS releases US oil, gas reserves growth estimates

Potential undiscovered US reserves additions total 32 billion bbl of crude oil, 291 tcf of natural gas, and 10 billion bbl of natural gas liquids, the US Geological Survey said in a new estimate of technically recoverable domestic oil and gas. The amounts represent about 10% of the overall US oil and gas endowment, and do not include reserve growth estimates for federal offshore areas, it said.
