The RRC has issued one drilling permit, issued March 5, 1985, permitted to 3,900 ft.
It was permitted by Ridge Oil Company and has since transferred to Yellow Rose Oil & Gas Oper. Inc. on the wellbore schedule.
Completion filings report one formation top, including Marble Falls.
Its 2 leases have reported 2.74K barrels of oil and 134K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
