Cook W. I. #20 (API 42-417-37522) is a well in Shackelford County operated by Stasney Well Service LLC, completed August 16, 1991.
The RRC has issued one drilling permit, issued July 12, 1991, permitted to 2,000 ft.
It was permitted by Young, Marshall R., Oil Company and has since transferred to Stasney Well Service LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Coleman Jct, Coleman Junction, Sedwick, Dothan.
Its 3 leases have reported 661K barrels of oil and 48.2K mcf of gas since January 1993, last reporting in July 2026. The leases carry 104 wells, so these are lease totals, not this well alone.
