Lambert M. F. #18 (API 42-391-01192) is a plugged well in Refugio County, plugged July 24, 1998, last operated by Hilcorp Energy Company.

The RRC has issued one drilling permit, issued April 11, 1991, permitted to 6,413 ft.

It was permitted by H & D Operating Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its 2 leases have reported 279K barrels of oil and 332K mcf of gas since January 1993, last reporting in July 2026. The leases carry 19 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.
