Jennings Ranch C #42 (API 42-505-34548) is a well in Zapata County operated by Hilcorp Energy Company, completed August 27, 2002 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued May 30, 2002, permitted to 12,800 ft.
It was permitted by Conoco Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 4 formation tops, including Perdido, Peridido, Wilcox, Wills Point.
Its 2 leases have reported 73 barrels of oil and 1.19M mcf of gas since August 2002, last reporting volume in August 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
