Thomas - Rife Gas Unit #4T (API 42-427-01311) is a well in Starr County operated by Merit Energy Company, completed June 16, 1986 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits between 1978 and 1986, permitted to 9,102 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Merit Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Frio, Vicksburg, Yegua.
Its 2 leases have reported 4.68K barrels of oil and 309K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
