Sterling County · Spraberry (Trend Area) field · Shut IN · Vertical
Cousins #1 (API 42-431-33314) is a well in Sterling County operated by Trigeo Energy LLC, completed August 31, 2011 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued April 15, 2011, permitted to 8,500 ft.
It was permitted by Steller Energy & Investment Corp and has since transferred to Trigeo Energy LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Coleman Junction, Upper Wolfecamp, Wolfcamp, Cisco.
Its lease has reported 43.6K barrels of oil and 164K mcf of gas since August 2011, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
