Mcelroy Ranch CO. -G- #22 (API 42-461-32051) is a well in Upton County operated by Diamondback E&P LLC, completed April 11, 1990 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits (amended once) between 1983 and 1990, permitted to 11,350 ft.

It was permitted by Chevron U. S. A. Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Anhy/Lime, Lime, Anhy, Lime/Anhy.

Its 3 leases have reported 50.1K barrels of oil and 2.4M mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 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.
