Mercer Alf 2st-H #H 2ST (API 42-055-34785) is a horizontal well in Caldwell County operated by Texas Petroleum Investment CO., completed January 29, 2003.

The RRC has issued 2 drilling permits between 1998 and 2001, permitted to 2,500 ft.

It was permitted by Vintage Petroleum, 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 2 leases have reported 1.06M barrels of oil and 55 mcf of gas since January 1993, last reporting in July 2026. The leases carry 40 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.
