Coke County · Jameson field · Shut In · Vertical
Jameson Reef Unit #4040 (API 42-081-31278) is a well in Coke County operated by Citation Oil & Gas Corp., completed November 30, 1984 and listed as shut in on the RRC schedule, shut in May 1, 2025.
The RRC has issued one drilling permit, issued August 10, 1984, permitted to 6,490 ft.
It was permitted by Sun Expl. & Prod. CO.-Abilene and has since transferred to Citation Oil & Gas Corp. on the wellbore schedule.
Completion filings report 3 formation tops, including Flippan Lime Marker, Jameson Strawn, Jameson Reef.
Its lease has reported 3.63M barrels of oil and 18.5M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 215 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
