Lamastus #1 (API 42-493-32112) is a plugged well in Wilson County, plugged January 16, 1996, last operated by P.S.N. Petroleum Inc..

The RRC has issued 2 drilling permits between 1989 and 2008, permitted to 4,600 ft.

It was permitted by AP Texas Energy, Inc. and has since transferred to P.S.N. Petroleum Inc. on the wellbore schedule.

Completion filings report 10 formation tops, including Midway, Navarro, Taylor, Anacacho.

Its 3 leases have reported 555 barrels of oil and 10 mcf of gas since January 1993, last reporting in July 2026. The leases carry 4 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.
