The RRC has issued one drilling permit, issued December 2, 2009, permitted to 11,000 ft.
It was permitted by Cog Operating LLC and has since transferred to Extex Operating Company on the wellbore schedule.
Completion filings report 6 formation tops, including Spraberry, Dean, Wolfcamp, Base Big Lime.
Its lease has reported 164K barrels of oil and 1.72M mcf of gas since August 2008, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
