Top 50 Public E&P Operators of 2025 Ranked by O&G Production

Enverus, a leading energy SaaS and analytics platform, has released its annual list of the top 50 public onshore exploration and production (E&P) companies in the U.S., based on gross-operated production last year. ExxonMobil leads the ranking again at 1.95 MMboe/d, followed by Expand Energy (formerly Chesapeake Energy) at 1.75 MMboe/d and ConocoPhillips, which climbed three positions to claim the No. 3 spot at 1.42 MMboe/d. Six of the top 10 companies list the Permian Basin as their primary operating region. Two of the top 10 are companies primarily operating in the Marcellus/Utica, including Expand Energy and EQT---the #1 and #2 gas-producing companies in the U.S., respectively. EOG Resources is also in the top 10. Although it's categorized as a Gulf Coast-focused driller, EOG has major assets and drilling activity in the Ohio Utica Shale.
