Gault 5-44 Unit 1 #221R (API 42-329-43729) is a horizontal well in Midland County operated by Diamondback E&P LLC, completed March 7, 2021 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued September 26, 2019, 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 10 formation tops, including Santa Rosa, Rustler, Queen, Yates.

Its lease has reported 298K barrels of oil and 1.1M mcf of gas since April 2020, last reporting in July 2026. The lease carries 2 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.
