The RRC has issued one drilling permit (amended once), issued March 18, 2011, permitted to 11,000 ft.

It was permitted by Cog Operating LLC and has since transferred to Winn Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Spraberry, Dean, Wolfcamp, L. Wolfcamp.

Its lease has reported 576K barrels of oil and 3.67M mcf of gas since November 2008, last reporting in July 2026. The lease carries 11 wells, so these are lease totals, not this well alone.
