Buda Limestone nears exhaustion as Texas energy focus shifts

Since drilling began in 1930, the formation has yielded 204 million barrels of oil and 287 billion cubic feet of gas. USGS Director Ned Mamula noted that these figures represent a final chapter for the formation, signaling a clear necessity for industry to pivot toward undiscovered resources elsewhere. With the Buda essentially tapped out, operators are intensifying their reliance on the overlying Eagle Ford Group to maintain regional production levels.

While the Buda fades, the Eagle Ford remains a critical engine for the U.S. energy sector. Output in the basin rose 2.2% on a barrels of oil equivalent basis through March 2026, maintaining a steady daily average between 2.36 and 2.46 million barrels. J. David Smith of Mercer Capital attributes this consistency to the basin's maturity, where producers have successfully balanced declining rig counts with strict capital discipline.

Infrastructure proximity to the U.S. Gulf Coast has turned the Eagle Ford into a specialized hub, particularly for natural gas. EOG Resources is spearheading this shift with its Dorado play, which is projected to hit 1 billion cubic feet per day in 2026. This evolution toward a hybrid model—blending stable crude extraction with aggressive gas growth—has also fueled a wave of consolidation, most notably Stone Ridge’s $2.3 billion acquisition of Baytex Energy’s assets.
