Wharton A. B. JR. E Joa #16 (API 42-165-36532) is a well in Gaines County operated by Sabinal Energy Operating LLC, completed July 27, 2006.

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 Adres.

Its 2 leases have reported 424K barrels of oil and 104K mcf of gas since March 2005, last reporting in July 2026. The leases carry 12 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.
