The RRC has issued one drilling permit, issued October 20, 1986, permitted to 2,800 ft.
It was permitted by Keck, W. M., JR., Mrs. and has since transferred to Eagle Ford Oil CO. Inc. on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its 3 leases have reported 39.4K barrels of oil and 71.5K mcf of gas since January 1993, last reporting in July 2026. The leases carry 103 wells, so these are lease totals, not this well alone.
