Lambert M. F. #124 U (API 42-391-01358) is a well in Refugio County operated by Hilcorp Energy Company, completed September 18, 1984 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 18, 1984, permitted to 5,855 ft.
It was permitted by Pennzoil Producing CO. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including 5,500, Tom O'Connor, 5,800.
Its 2 leases have reported 23.1M barrels of oil and 15.7M mcf of gas since January 1993, last reporting in July 2026. The leases carry 620 wells, so these are lease totals, not this well alone.
