South Texas Syndicate -A- #22 (API 42-311-32914) is a well in Mcmullen County operated by Caribbean Energy LLC II, completed February 1, 2006.
The RRC has issued 2 drilling permits between 1991 and 2012, permitted to 4,800 ft.
It was permitted by Whiting Oil And Gas Corporation and has since transferred to Caribbean Energy LLC II on the wellbore schedule.
Completion filings report 10 formation tops, including Yegua, Queen City, Carrizo, Anacacho.
Its 2 leases have reported 619K barrels of oil and 938 mcf of gas since January 1993, last reporting in July 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 794K barrels injected in the 12 months reported through January 2026.
