Tankersly (West) #4 (API 42-133-32428) is a well in Eastland County operated by Mustang Oil & Gas Corporation, completed May 26, 1984.
The RRC has issued 2 drilling permits between 1980 and 1984, permitted to 4,000 ft.
It was permitted by Ridge Oil Company and has since transferred to Mustang Oil & Gas Corporation on the wellbore schedule.
Completion filings report 3 formation tops, including Strawn, Caddo, Marble Falls.
Its 3 leases have reported 196 barrels of oil and 50.8K mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
