The RRC has issued one drilling permit, issued July 28, 2009, permitted to 6,312 ft.

It was permitted by Virtex Operating Company, Inc. and has since transferred to Trailblazer Energy Resources LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Midway, Escondidop, Olmos, Buda.

Its lease has reported 484K barrels of oil and 3.4M mcf of gas since May 2009, last reporting in July 2026. The lease carries 8 wells, so these are lease totals, not this well alone.
