Jackson County · West Ranch (Marginulina 5000) field · Observation · Vertical
West Ranch -A- #433 (API 42-239-02780) is a well in Jackson County operated by Hilcorp Energy Company, completed August 1, 2017 and listed as observation on the RRC schedule, shut in February 1, 2026.
The RRC has issued 2 drilling permits between 1987 and 2005, permitted to 5,850 ft.
It was permitted by Vintage Petroleum, Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 6 formation tops, including Catahoula, Frio, Marg. 5000, Greta.
Its 2 leases have reported 6M barrels of oil and 5.8M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 288 wells, so these are lease totals, not this well alone.
