EIA reserve estimates for USA for 2016 have been issued (a couple of months later than usual). The numbers they provide are ‘proven’ reserves of crude, condensate and natural gas. The data is provided directly by the E&Ps with some adjustments made by EIA for missing numbers. U.S. crude oil and lease condensate proved reserves increased by 6.8 billion barrels (19.2%) in 2017, as the combination of total discoveries of 5.7 billion barrels and net revisions, net acquisitions, and adjustments totaling 4.5 billion barrels exceeded 2017 annual production of 3.4 billion barrels (Figure 9a). The USGS estimates that the mean potential undiscovered, conventional reserve additions for the United States total 32 billion barrels (bb) of oil, 291 trillion cubic feet (tcf) of natural gas, and 10 bb of natural gas liquids, constituting about 10 percent of the overall U.S. oil and gas endowment.

Rystad’s analysis includes oil in proven, existing fields, oil that has been discovered and will probably be recoverable, as well as an estimate for recoverable oil in as-yet discovered oil fields. More than 50% of the United States oil reserves come in the form of “unconventional shale oil,” Proven oil reserves in the United States were 43.8 billion barrels of crude oil as of the end of 2018, excluding the Strategic Petroleum Reserve. The 2018 reserves represent the largest US proven reserves since 1972. The Energy Information Administration estimates US undiscovered, technically recoverable oil resources to be an additional 198 billion barrels. Figure 1: Magnitude of uncertainty in reserves estimates The oil and gas reserves estimation methods can be grouped into the following categories: 1. Analogy, 2. Volumetric, 3. Decline analysis, 4. Material balance calculations for oil reservoirs, 5. Material balance calculations for gas reservoirs, 6. Reservoir simulation. The Eagle Ford Group of Texas contains estimated means of 8.5 billion barrels of oil, 66 trillion cubic feet of natural gas, and 1.9 billion barrels of natural gas liquids, according to a new assessment by the U.S. Geological Survey. This estimate consists of undiscovered, technically recoverable resources in continuous accumulations.
