Mcdermott C. W. #4 (API 42-089-30642) is a well in Colorado County operated by Mountain V Texas LLC, completed October 1, 1989 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended twice) between 1977 and 1989, permitted to 10,152 ft.
It was permitted by Mitchell Energy Corporation and has since transferred to Mountain V Texas LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Frio, Cook Mountain, Yegua, Wilcox.
Its 3 leases have reported 194K barrels of oil and 92.7K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
