West Ranch A #502 (API 42-239-32009) is a well in Jackson County operated by Hilcorp Energy Company, completed March 17, 1994.

The RRC has issued 4 drilling permits between 1984 and 2003, permitted to 5,900 ft.

It was permitted by Vintage Petroleum, Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 4 formation tops, including Catahoula, Marginulina 5000, Frio, Gretta.

Its 3 leases have reported 712K barrels of oil and 657K mcf of gas since January 1993, last reporting in July 2026. The leases carry 45 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.
