Tweedy #31 (API 42-451-32080) is a well in Tom Green County operated by Lainco Inc., completed March 17, 1992 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 21, 1991, permitted to 1,200 ft.

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

Completion filings report 2 formation tops, including San Andres, San Angelo.

Its lease has reported 449K barrels of oil and 625 mcf of gas since January 1993, last reporting in July 2026. The lease carries 42 wells, so these are lease totals, not this well alone.

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