The RRC has issued one drilling permit, issued July 28, 1983, permitted to 4,870 ft.
It was permitted by Williams, Clayton W., JR. and has since transferred to San Dia Producing Company on the wellbore schedule.
Completion filings report one formation top, including Navarro.
Its 2 leases have reported 1.16K barrels of oil and 93.9K 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.
