Swain W. F. 36 #10 (API 42-467-30785) is a well in Van Zandt County operated by Basa Resources Inc., completed May 12, 1990.
The RRC has issued 2 drilling permits between 1990 and 2014, permitted to 3,250 ft.
It was permitted by Union Oil Company Of California and has since transferred to Basa Resources Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Pecan Gap, Austin Chalk, Woodbine.
Its 2 leases have reported 317K barrels of oil and 701K 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 4.81M barrels injected in the 12 months reported through August 2025.
