Jackson County · West Ranch (Greta) field · Observation · Vertical
West Ranch -A- #427 (API 42-239-02774) 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 4 drilling permits (amended once) between 1981 and 2000, permitted to 5,851 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, Marginulina 5000, Frio, Gretta.
Its 4 leases have reported 6.27M barrels of oil and 11.1M mcf of gas since January 1993, last reporting in July 2026. The leases carry 316 wells, so these are lease totals, not this well alone.
