The RRC has issued one drilling permit (amended once), issued April 23, 2012, permitted to 14,000 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to San Isidro Development CO L. C. on the wellbore schedule.

Its lease has reported 606K barrels of oil and 1.29M mcf of gas since August 2011, last reporting in February 2025. The lease carries 8 wells, so these are lease totals, not this well alone.
