The RRC has issued one drilling permit (amended once), issued March 5, 2013, permitted to 12,500 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Manti Tarka Permian OP LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Lamar, Bone Spring.
Its lease has reported 415K barrels of oil and 418K mcf of gas since May 2013, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
