Shannon M. A. Est. #36 (API 42-105-32525) is a plugged well in Crockett County, plugged June 6, 2024, last operated by Vanco Oil & Gas Corp..

The RRC has issued 2 drilling permits between 1979 and 1986, permitted to 1,700 ft.

It was permitted by Wintershall Oil & Gas Coporation and has since transferred to Vanco Oil & Gas Corp. on the wellbore schedule.

Completion filings report 4 formation tops, including Queen, Grayburg, Top/Mc Elroy, San Andres.

Its 2 leases have reported 309K barrels of oil and 1.57K mcf of gas since January 1993, last reporting in July 2026. The leases carry 75 wells, so these are lease totals, not this well alone.
