The RRC has issued 2 drilling permits between 1983 and 1998, permitted to 9,720 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Bkm Production on the wellbore schedule.
Completion filings report 10 formation tops, including Baker, Baker Sand, Davis, Davis Sand.
Its 2 leases have reported 44.3K barrels of oil and 652K 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.
