Tweedy D #1 (API 42-451-31732) is a well in Tom Green County operated by Lainco Inc., completed January 22, 1987 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued July 8, 1986, 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 4 formation tops, including Base Cretaceous (marker), Queen, Grayburg, San Andres.

Its lease has reported 26.4K barrels of oil and 96 mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 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.
