Davis Estate #1 (API 42-203-31525) is a plugged well in Harrison County, plugged December 12, 2019, last operated by Shelby Operating Company.
The RRC has issued 2 drilling permits between 1986 and 1990, permitted to 10,000 ft.
It was permitted by Winchester Production Company and has since transferred to Shelby Operating Company on the wellbore schedule.
Completion filings report 4 formation tops, including Massive Anhydrite (marker), Pettit, Travis Peak, Cotton Valley.
Its 3 leases have reported 43.6K barrels of oil and 120K 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.
