EOG Resources, Inc.

The state's monthly reports list 4,868 leases under EOG Resources, Inc. at some point. Of those, 283 are reported by another operator today (93 by Highmark Energy Operating, LLC, 83 by Lewis Petro Properties, Inc., 39 by Laguna Texas Resources, LLC, 68 by others); 3,665 still report production under EOG Resources, Inc.; 556 stopped reporting while it was the operator.

Counted from the operator named on each lease’s monthly production report, Jan 2020 to Aug 2026. A date is the month the reports changed, not the day of a sale. A lease can move without the company being sold, and the company that pays you is not always the operator.
