West Ranch A #486 (API 42-239-31251) is a plugged well in Jackson County, plugged January 30, 2017, last operated by Hilcorp Energy Company.

The RRC has issued 3 drilling permits (amended once) between 1978 and 1991, permitted to 6,231 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its 2 leases have reported 6M barrels of oil and 5.64M mcf of gas since January 1993, last reporting in July 2026. The leases carry 288 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.
