Refugio County · Tom Oconnor (5900 Sand) field · Vertical
Lambert M. F. #H117 (API 42-391-31378) is a well in Refugio County operated by H & D Operating Company, completed March 4, 1980.
The RRC has issued 2 drilling permits between 1980 and 1992, permitted to 6,000 ft.
It was permitted by Quintana Pet. Corp. and has since transferred to H & D Operating Company on the wellbore schedule.
Completion filings report 7 formation tops, including Lagarto, Oakville, Catahoula, Anahuac.
Its 2 leases have reported 22.8M barrels of oil and 14.9M mcf of gas since January 1993, last reporting in July 2026. The leases carry 601 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 444K barrels injected in the 12 months reported through September 2025.
