Jennings Ranch AA #36 (API 42-505-34906) is a well in Zapata County operated by Hilcorp Energy Company, completed September 1, 2004 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 20, 2004, permitted to 13,250 ft.

It was permitted by Conocophillips Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 3 formation tops, including Perdido, Wilcox, Wills Point.

Its 2 leases have reported 4.74K barrels of oil and 5.37M mcf of gas since September 2004, last reporting volume in August 2026. The leases carry 2 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.
