The Eagle Ford shale play has shown remarkably consistent crude oil production and rising natural gas output in recent years. A formation beneath the Eagle Ford has been producing for nearly a century, but now it has its remaining resources nearly exhausted.<\/p>\n
The Buda Limestone formation, which lies beneath the Eagle Ford Group, has limited remaining oil and gas resources, the latest analysis by the U.S. Geological Survey (USGC) showed<\/a> this week.<\/p>\n Technically recoverable resources at Buda Limestone are estimated at 184 billion cubic feet of gas and 12 million barrels of oil. These are just a fraction of what the formation has produced since around 1930, when oil and gas output in the formation began.<\/p>\n The Eagle Ford Group, which lies above the Buda, is the primary source for the undiscovered oil and gas at the formation, according to the USGC.<\/p>\n Since production began around 1930, the Buda Limestone has produced 204 million barrels of oil, or the equivalent of 10 days of U.S. consumption at the 2025 rate, and 287 billion cubic feet of gas, which is equal to three days of the current consumption for the United States.<\/p>\n Set OilPrice.com as a preferred source in Google here<\/a>.<\/p>\n \u201cThe U.S. economy and our way of life depend on energy, and USGS oil and gas assessments point to resources that industry hasn\u2019t discovered yet,\u201d USGS Director Ned Mamula said in a statement.<\/p>\n \u201cIn this case, the Buda Limestone has little remaining undiscovered oil or gas, indicating a need for new resources,\u201d the official added.<\/p>\n With Buda left with little technically recoverable resource, operators are betting on the Eagle Ford and the other shale formations in the U.S. to boost production.<\/p>\n Oil and gas production at Eagle Ford rose by 2.2% on a barrels of oil equivalent (boe) basis for the twelve-month period ending March 2026, compared to the same period of the previous year, valuation and advisory firm Mercer Capital said<\/a> earlier this year.<\/p>\n The basin\u2019s growth was closely aligned with the other major U.S. shale basins, including the Permian, Haynesville, and Appalachia.<\/p>\n Eagle Ford\u2019s production remained within a relatively narrow range in the 12 months to March, varying between 2.36 and 2.46 million barrels of oil equivalent per day (boepd).<\/p>\n \u201cThe Eagle Ford exhibited modest production growth over the past year, broadly in line with other major basins, as output remained within a relatively narrow range,\u201d said J. David Smith, Senior Vice President at Mercer Capital.<\/p>\n \u201cThis stability reflects the basin\u2019s maturity, with limited variability in production despite declining rig counts and continued capital discipline among operators.\u201d<\/p>\n Oil production at the Eagle Ford remains relatively stable while natural gas output is growing, with major players including EOG Resources focusing on the gas portion in the shale play.<\/p>\n Crude oil production has remained at about 1.1 million barrels per day (bpd), while natural gas production is rising, due to Eagle Ford\u2019s premium access to the U.S. Gulf Coast markets. Due to the proximity to the Gulf Coast, the Eagle Ford gas enjoys favorable wellhead pricing dynamics relative to other plays, according to an analysis<\/a> by Energy Advisors.<\/p>\n The Dorado gas play, led by EOG, is a major driver of natural gas production in the Eagle Ford, with production expected to reach 1 Bcf\/d in 2026, up by 33% on the year, and with low breakevens.<\/p>\n The Eagle Ford has also become a hotspot for mergers and acquisitions, particularly for proved developed producing (PDP) assets. In recent months, Stone Ridge bought Eagle Ford assets from Baytex Energy for $2.3 billion.<\/p>\n \u201cThe Eagle Ford is evolving into a hybrid play\u2014combining stable oil production with advantaged gas growth and continued M&A activity,\u201d Energy Advisors noted.<\/p>\n By Tsvetana Paraskova for Oilprice.com<\/a><\/p>\n
