West Ranch (41-A/98-A Cons) Unit #285 (API 42-239-02633) 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 1978 and 1988, permitted to 6,191 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Catahoula, Frio, Gretta.
Its 3 leases have reported 11.3M barrels of oil and 2.76M mcf of gas since the record begins in January 1993, last reporting volume in July 2026. The leases carry 401 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
