Jennings Ranch C #40 (API 42-505-34574) is a well in Zapata County operated by Hilcorp Energy Company, completed May 15, 2003 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued July 1, 2002, permitted to 13,098 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 1.72K barrels of oil and 978K mcf of gas since May 2003, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
