Lockhart & Brown & Olson #4 (API 42-003-40705) is a well in Andrews County operated by Crescent Energy Operating LLC, completed September 29, 2021 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 11, 2008, permitted to 4,751 ft.

It was permitted by OK Arena Operating Company and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Rustler, Yates, Grayburg, San Andres.

Its lease has reported 96.6K barrels of oil and 47.7K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
