Tweedy AF #10 (API 42-451-31480) is a well in Tom Green County operated by Swartz Oil Company, completed August 31, 1994.

The RRC has issued one drilling permit, issued October 31, 1984, permitted to 1,200 ft.

It was permitted by Swartz, Guy A. and has since transferred to Swartz Oil Company on the wellbore schedule.

Completion filings report 3 formation tops, including Queen, San Andres, San Angelo.

Its 2 leases have reported 462K barrels of oil and 841 mcf of gas since January 1993, last reporting in July 2026. The leases carry 55 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 12.6K barrels injected in the 12 months reported through January 2026.

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