The Eagle Ford Group of Texas comprises estimated technique of eight.5 Bbbl of oil, 66 Tcf of pure gasoline, and 1.9 Bbbl of pure gasoline liquids, in accordance with a brand new evaluation by the U.S. Geological Survey. This estimate consists of undiscovered, technically recoverable sources in steady accumulations.
“Texas is so well-known for its historical past of oil and gasoline manufacturing that it’s nearly synonymous with petroleum,” mentioned Dr. Jim Reilly, USGS director. “Texas continues to stay within the forefront of our Nation's vitality provide chain with outstanding will increase in manufacturing and reserves as a result of revolutionary unconventional strategies used to launch beforehand unrecoverable sources.”
The Eagle Ford Group stretches from the Texas-Mexico border to the west, throughout parts of southern and japanese Texas to the Texas-Louisiana border to the east. It is without doubt one of the most prolific steady accumulations within the United States, and is comprised of mudstone with various quantities of carbonate.
“The USGS gives worth to the Nation by delivering unbiased assessments of U.S. and world vitality sources,” mentioned Dr. Reilly. “We usually reassess potential sources, as we’ve for the Eagle Ford on this report, in response to modifications in estimated final restoration as new strategies or productive horizons are pioneered.”
The Eagle Ford Group has lengthy been recognized to include oil and gasoline, nevertheless it was not till 2008 that manufacturing of the continual sources actually obtained underway in East Texas.
“This evaluation is a bit completely different than earlier ones, as a result of it ranks within the prime 5 of assessments we’ve performed of steady sources for each oil and gasoline,” mentioned USGS scientist Kate Whidden, lead writer for the evaluation. “Usually, formations produce primarily oil or gasoline, however the Eagle Ford is wealthy in each.”
Continuous oil and gasoline is dispersed all through a geologic formation fairly than current as discrete, localized occurrences, similar to these in standard accumulations. Because of that, steady sources generally require particular technical drilling and restoration strategies, similar to hydraulic fracturing.
Undiscovered sources are these which can be estimated to exist based mostly on geologic information and statistical evaluation of recognized sources, whereas technically recoverable sources are these that may be produced utilizing at present accessible expertise and business practices. Whether or not it’s worthwhile to supply these sources has not been evaluated.
The USGS is the one supplier of publicly accessible estimates of undiscovered technically recoverable oil and gasoline sources of onshore lands and offshore state waters. The USGS evaluation of the Eagle Ford Group was undertaken as a part of a nationwide mission assessing home petroleum basins utilizing standardized methodology and protocol.
