Gaskins 21 #1 (API 42-227-36401) is a well in Howard County operated by Diamondback E&P LLC, completed March 30, 2011 and listed as shut in on the RRC schedule.

The RRC has issued 2 drilling permits between 2010 and 2011, permitted to 12,000 ft.

It was permitted by Cobra Oil & Gas Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.

Its lease has reported 212K barrels of oil and 725K mcf of gas since December 2010, last reporting in July 2026. The lease carries 3 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.
