Greer Sikes 42-41 F #261 (API 42-383-41084) is a horizontal well in Reagan County operated by Diamondback E&P LLC, completed August 23, 2022 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued December 21, 2021, permitted to 11,000 ft.

It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Queen, Grayburg, San Andres, Clear Fork.

Its lease has reported 382K barrels of oil and 3.76M mcf of gas since August 2022, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
