Trammell H. S. #45 (API 42-055-33706) is a well in Caldwell County operated by Texas Petroleum Investment CO., completed August 1, 1986 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued November 6, 1984, permitted to 2,290 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Texas Petroleum Investment CO. on the wellbore schedule.

Completion filings report 6 formation tops, including Austin Chalk, Eagle Ford, Buda, Del Rio.

Its lease has reported 685K barrels of oil and 50 mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 34 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.
