Mabee 139 X6 #417H (API 42-317-39838) is a horizontal well in Martin County operated by Cog Operating LLC, completed November 30, 2014.
The RRC has issued one drilling permit, issued October 10, 2014, permitted to 12,500 ft.
It was permitted by Oxy USA Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yates, Seven Rivers, Queen, Grayburg.
Its 2 leases have reported 4.5M barrels of oil and 10.1M mcf of gas since April 2008, last reporting in July 2026. The leases carry 125 wells, so these are lease totals, not this well alone.
