The RRC has issued one drilling permit, issued July 18, 1995, permitted to 7,186 ft.
It was permitted by R K Petroleum Corporation and has since transferred to Wtg Exploration on the wellbore schedule.
Completion filings report 3 formation tops, including Delaware, B/Manzanita, Brushy Canyon.
Its lease has reported 163K barrels of oil and 126K mcf of gas since September 1995, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
