West Ranch -A- #488 (API 42-239-31249) is a well in Jackson County operated by Hilcorp Energy Company, completed August 22, 1989.

The RRC has issued 5 drilling permits (amended once) between 1978 and 1991, permitted to 6,321 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 4 leases have reported 6.44M barrels of oil and 6.55M mcf of gas since January 1993, last reporting in July 2026. The leases carry 342 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.
