West Ranch -A- #477 (API 42-239-30542) is a well in Jackson County operated by Hilcorp Energy Company, completed December 31, 1974.

The RRC has issued 6 drilling permits between 1979 and 1990, permitted to 6,441 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 6 formation tops, including Catahoula, Frio, Gretta, Toney.

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 290 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.
