Martin County · Spraberry (Trend Area) field · Producing · Horizontal
Mabee 138 #705H (API 42-317-36666) is a horizontal well in Martin County operated by Cog Operating LLC, completed February 14, 2014 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 2011 and 2015, permitted to 13,500 ft.
It was permitted by Reliance Energy, Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 12 formation tops, including Santa Rosa, Yates, Queen, Grayburg.
Its 2 leases have reported 1.46M barrels of oil and 7.09M mcf of gas since January 2011, last reporting in July 2026. The leases carry 10 wells, so these are lease totals, not this well alone.
