Exxon Mobil’s decision to market its Eagle Ford assets reflects a mature basin position where permitting peaked in 2017–2019 and has since declined to near-zero activity, signaling a shift from growth to harvest mode. Permit data shows development concentrated in core counties like La Salle, Karnes, and Atascosa and primarily within the Eagleville and Sugarkane fields, reinforcing that the sale aligns with Exxon’s strategic pivot toward higher-growth assets in the Permian Basin and Guyana.
