Lopez J. M. #1
Zapata County · Roleta (Wilcox Consolidated) field · Producing · Vertical
Lopez J. M. #1 (API 42-505-34251) is a well in Zapata County operated by Hilcorp Energy Company, completed April 2, 2001 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 7, 2000, permitted to 8,500 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 Carrizo, 7650 Sand, C-5, C-5 Sand.
Its 2 leases have reported 4.08K barrels of oil and 719K mcf of gas since February 2001, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
