The RRC has issued one drilling permit, issued May 4, 1984, permitted to 10,400 ft.
It was permitted by Shar-Alan Oil Company and has since transferred to Gsi Oil & Gas Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Austin Chalk, Sub-Clarksville, Woodbine.
Its lease has reported 309K barrels of oil and 23.2K mcf of gas since January 1993, last reporting in April 2018. The lease carries 2 wells, so these are lease totals, not this well alone.
