West Ranch (41-A/98-A Cons) Unit #491 (API 42-239-31253) is a well in Jackson County operated by Hilcorp Energy Company, completed June 5, 2020 and listed as shut in on the RRC schedule, shut in February 1, 2021.

The RRC has issued 2 drilling permits between 1978 and 1989, permitted to 6,222 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, Greta.

Its 4 leases have reported 11.6M barrels of oil and 3.67M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 452 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
