Jennings Ranch AA #28 (API 42-505-34704) is a plugged well in Zapata County, plugged December 9, 2021, last operated by Hilcorp Energy Company.

The RRC has issued one drilling permit, issued April 8, 2003, permitted to 13,600 ft.

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

Completion filings report 4 formation tops, including Perdido, Wilcox, Base Lwr Wilcox, Wills Point.

Its 2 leases have reported 12 barrels of oil and 866K mcf of gas since October 2003, with no volume in the three years through 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.
