Devil S Waterhole Unit #L01
McMullen County · Devils Water Hole (7000) field · Shut IN · Vertical
Devil S Waterhole Unit #L01 (API 42-311-30571) is a well in Mcmullen County operated by Nitro Oil & Gas LLC, completed July 14, 1984 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued September 27, 1984, permitted to 8,800 ft.
It was permitted by Petro-Lewis Corporation and has since transferred to Nitro Oil & Gas LLC on the wellbore schedule.
Completion filings report one formation top, including Wilcox.
Its lease has reported 243K barrels of oil and 83.2K mcf of gas since January 1993, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Petro-Lewis Corporation; the EWA schedule now lists a different operator.
