The RRC has issued one drilling permit, issued July 5, 1994, permitted to 4,730 ft.
It was permitted by Rust Oil Corp. and has since transferred to Vin Fisher Operating Inc. on the wellbore schedule.
Completion filings report 2 formation tops, including Yates, San Andres.
Its 2 leases have reported 46.3K barrels of oil and 100K mcf of gas since September 1994, last reporting in July 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
