Refugio County · Greta Deep (5800) field · Vertical
Lambert M. F. H #H109 (API 42-391-31263) is a well in Refugio County operated by Pennzoil Exploration & Prod. CO., completed January 2, 1980.
The RRC has issued 4 drilling permits (amended once) between 1978 and 2010, permitted to 6,000 ft.
It was permitted by Hilcorp Energy Company and has since transferred to Pennzoil Exploration & Prod. CO. on the wellbore schedule.
Completion filings report 7 formation tops, including Lagarto, Oakville, Greta, Miocene (undifferentiated).
Its 4 leases have reported 771 barrels of oil and 61.6K mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
