Swain D. L. 11 -AC- #25 (API 42-467-31073) is a well in Van Zandt County operated by Basa Resources Inc., completed October 29, 2004 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued August 5, 2004, permitted to 2,950 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 Nacatoch, Pecan Gap, Austin Chalk.

Its lease has reported 850K barrels of oil and 438K mcf of gas since January 1993, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 67.5K barrels injected in the 12 months reported through August 2025.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
