The RRC has issued one drilling permit (amended once), issued February 1, 2012, permitted to 10,565 ft.
It was permitted by Merit Energy Company and has since transferred to Civitas Permian Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Atoka, Mississippian.
Its lease has reported 734K barrels of oil and 1.13M mcf of gas since January 1993, last reporting volume in March 2026. The lease carries 18 wells, so these are lease totals, not this well alone.
