Zapata County · Munoz (Lobo) field · Producing · Vertical
Bustamante Gas Unit 1 #3 (API 42-505-32377) is a well in Zapata County operated by Hilcorp Energy Company, completed April 1, 1997 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1986 and 1987, permitted to 14,259 ft.
It was permitted by Transamerican Natural Gas Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Wilcox, Wills Point, Wills Pt.
Its 2 leases have reported 74 barrels of oil and 1.56M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
