Jameson Reef Unit #427
Coke County · Jameson field · Vertical
Jameson Reef Unit #427 (API 42-081-30227) is a well in Coke County operated by Sheridan Production Company LLC, completed March 29, 1993.
The RRC has issued one drilling permit (amended once), issued September 8, 1988, permitted to 6,430 ft.
It was permitted by Sun Exploration & Production CO. and has since transferred to Sheridan Production Company LLC on the wellbore schedule.
Completion filings report one formation top, including Reef.
Its 2 leases have reported 3.63M barrels of oil and 18.6M mcf of gas since January 1993, last reporting in July 2026. The leases carry 216 wells, so these are lease totals, not this well alone.
