The RRC has issued one drilling permit, issued November 21, 1986, permitted to 2,600 ft.
It was permitted by Sequoia Oil & Gas, Inc. and has since transferred to Xplore Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Strawn.
Its 2 leases have reported 15.8K barrels of oil and 41.3K mcf of gas since January 1993, last reporting in April 2021. The leases carry 6 wells, so these are lease totals, not this well alone.
