The RRC has issued one drilling permit (amended once), issued October 9, 1987, permitted to 11,700 ft.
It was permitted by Lowmar Exploration Company and has since transferred to Dominion Minerals Corporation on the wellbore schedule.
Completion filings report 4 formation tops, including Vicksburg, Yegua, Cook Mountain, Wilcox.
Its 2 leases have reported 45.6K barrels of oil and 33.4K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
