West Ranch -A- #513 (API 42-239-32215) is a well in Jackson County operated by Hilcorp Energy Company, completed August 1, 2017 and listed as observation on the RRC schedule, shut in February 1, 2026.

The RRC has issued 3 drilling permits between 1985 and 1990, permitted to 6,470 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 10 formation tops, including Catahoula, Marginulina, Marginulina 5000, Marginulina5000.

Its 2 leases have reported 6M barrels of oil and 6.02M mcf of gas since January 1993, last reporting volume in April 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.
