Refugio County · Tom O Connor (4150) field · Vertical
Lambert M. F. #131 (API 42-391-31694) is a plugged well in Refugio County, plugged July 13, 1990, last operated by Hilcorp Energy Company.
The RRC has issued one drilling permit, issued December 9, 1983, permitted to 4,600 ft.
It was permitted by Hewit & Dougherty and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report one formation top, including 4150'.
Its lease has reported 193K barrels of oil and 157K mcf of gas since January 1993, last reporting in August 2021. The lease carries 10 wells, so these are lease totals, not this well alone.
