The RRC has issued one drilling permit (amended once), issued December 2, 1993, permitted to 3,000 ft.
It was permitted by Sonat Exploration CO. - Houston and has since transferred to Killam Oil CO. Ltd. on the wellbore schedule.
Completion filings report 4 formation tops, including Cole, Govt Wells, Govt. Wells, Mirando.
Its lease has reported 72.6K barrels of oil and 7 mcf of gas since March 1994, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
