Jennings Ranch C #53 (API 42-505-34701) is a well in Zapata County operated by Hilcorp Energy Company, completed June 5, 2003 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued April 1, 2003, permitted to 12,761 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 24 barrels of oil and 1.06M mcf of gas since June 2003, last reporting volume in August 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
