Mcdermott C. W. #6 (API 42-089-31814) is a well in Colorado County operated by Mountain V Texas LLC, completed July 27, 1995 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued November 14, 1990, permitted to 7,200 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 Catahoula, B, Frio, B. Frio, T. Yegua.
Its lease has reported 194K barrels of oil and 92.7K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 29.7K barrels injected in the 12 months reported through May 2025.
