Harrison County · Waskom (Page Sand) field · Vertical
Knighton #4 (API 42-203-31143) is a plugged well in Harrison County, plugged August 4, 2021, last operated by Brookston Energy Inc..
The RRC has issued 4 drilling permits between 1984 and 1988, permitted to 7,000 ft.
It was permitted by Winchester Production Company and has since transferred to Brookston Energy Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Massive Anhydrite (marker), Pettit, Travis Peak.
Its 2 leases have reported 1.78K barrels of oil and 205K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
