The RRC has issued one drilling permit, issued January 29, 2007, permitted to 8,300 ft.
It was permitted by Mariner Energy, Inc. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report one formation top, including Canyon.
Its 2 leases have reported 1.79K barrels of oil and 236K mcf of gas since October 2007, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
