Buffin #1
Harrison County · Waskom (Cotton Valley) field · Vertical
Buffin #1 (API 42-203-31906) is a plugged well in Harrison County, plugged October 25, 2023, last operated by Four Diamond Operating LLC.
The RRC has issued one drilling permit, issued March 15, 1990, permitted to 10,000 ft.
It was permitted by Marshall Expl. Inc. and has since transferred to Four Diamond Operating LLC on the wellbore schedule.
Completion filings report 8 formation tops, including Glen Rose, Massive Anhydrite (marker), Base Mass. Anhydrite, B/Massive Anhydrite.
Its 2 leases have reported 116 barrels of oil and 556K 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.
