The RRC has issued one drilling permit (amended once), issued January 28, 2013, permitted to 13,525 ft.

It was permitted by Reliance Energy, Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Strawn, Atoka.

Its lease has reported 5.24M barrels of oil and 12.8M mcf of gas since February 2010, last reporting in July 2026. The lease carries 58 wells, so these are lease totals, not this well alone.
