The RRC has issued 2 drilling permits between 1980 and 1991, permitted to 7,500 ft.
It was permitted by Pendragon Oil CO. and has since transferred to First Rock Inc. on the wellbore schedule.
Completion filings report one formation top, including Top Chalk.
Its 2 leases have reported 85K barrels of oil and 27.3K mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
