Zapata County · La Perla (Lobo Cons.) field · Producing · Vertical
Martin J. C. #9 (API 42-505-31587) is a well in Zapata County operated by Hilcorp Energy Company, completed April 5, 2008 and listed as producing on the RRC schedule, shut in October 1, 2025.
The RRC has issued 2 drilling permits between 1982 and 2008, permitted to 10,120 ft.
It was permitted by Conocophillips Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 2 formation tops, including Queen City, Wilcox.
Its 2 leases have reported 12 barrels of oil and 1.22M mcf of gas since January 1993, last reporting volume in September 2025. The leases carry 2 wells, so these are lease totals, not this well alone.
