Lambert M. F. #57 (API 42-391-01342) is a well in Refugio County operated by Hilcorp Energy Company, completed March 7, 1985 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 28, 1983, permitted to 5,915 ft.
It was permitted by Pennzoil Producing CO. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 2 formation tops, including 4400', 5900'.
Its lease has reported 1.73M barrels of oil and 2.54M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 45 wells, so these are lease totals, not this well alone.
