Swain O. L. 11 B #15 (API 42-467-30707) is a plugged well in Van Zandt County, plugged January 13, 2016, last operated by Basa Resources Inc..

The RRC has issued 2 drilling permits between 1988 and 2000, permitted to 2,315 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 2 formation tops, including Pecan Gap, Austin Chalk.

Its 2 leases have reported 246K barrels of oil and 430K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
