The RRC has issued one drilling permit, issued June 13, 1995, permitted to 13,100 ft.
It was permitted by Enron Oil & Gas Company and has since transferred to Oxy USA Wtp LP on the wellbore schedule.
Completion filings report 9 formation tops, including Yates, Grayburg, Wolfcamp, Canyon.
Its lease has reported 3.07M barrels of oil and 2.07M mcf of gas since January 1995, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
