Lambert M. F. #48 (API 42-391-01386) is a plugged well in Refugio County, plugged May 31, 2001, last operated by Hilcorp Energy Company.

The RRC has issued 2 drilling permits between 1982 and 1985, permitted to 5,938 ft.

It was permitted by Pennzoil Producing CO. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its lease has reported 315K barrels of oil and 830K mcf of gas since January 1993, last reporting in July 2026. The lease carries 26 wells, so these are lease totals, not this well alone.
