West Ranch (41-A/98-A Cons) Unit #509J (API 42-239-32134) is a well in Jackson County operated by Hilcorp Energy Company, completed June 4, 2016 and listed as observation on the RRC schedule, shut in February 1, 2026.

The RRC has issued 4 drilling permits between 1984 and 1990, permitted to 6,360 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 9 formation tops, including Catahoula, Marginulina 5000, Frio, Greta.

Its 4 leases have reported 17.4M barrels of oil and 8.39M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The leases carry 688 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.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Wells named West Ranch (41-a/98-a Cons) Unit

Hilcorp Energy Company's other wells filed under this lease name in Jackson County, newest permit first. The RRC gives a gas well its own lease number, so the name is what joins the wells of a unit.

Chain of custody

Operator on the lease's P-4

Each operator named on the P-4 filings for this well's lease (a gas well is its own lease), from the date its filing took effect. The P-4 is filed by lease, so a date before the well was drilled is the lease's.
