Wharton A.B.JR. C Joa #18 (API 42-165-36534) is a well in Gaines County operated by Sabinal Energy Operating LLC, completed December 1, 2010.

The RRC has issued one drilling permit, issued March 16, 2006, permitted to 6,000 ft.

It was permitted by Chevron U. S. A. Inc. and has since transferred to Sabinal Energy Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Yates, Grayburg, San Andres.

Its 2 leases have reported 85.2K barrels of oil and 29.6K mcf of gas since May 2004, last reporting in July 2026. The leases carry 7 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.
