Trappe #1 (API 42-493-31540) is a horizontal well in Wilson County operated by First Light Operating LLC, completed May 15, 1984.

The RRC has issued 3 drilling permits (amended once) between 1984 and 2012, permitted to 8,000 ft.

It was permitted by First Rock, Inc. and has since transferred to First Light Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Taylor, Anacacho, Austin Chalk, Eagle Ford.

Its 2 leases have reported 40.6K barrels of oil and 12.1K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 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.
