Crane County · Sand Hills (McKnight) field · Shut IN · Vertical
Tubb J. B. -A- #28 (API 42-103-31283) is a well in Crane County operated by Ring Energy Inc., completed June 16, 1976 and listed as shut in on the RRC schedule, shut in October 1, 2019.
The RRC has issued one drilling permit (amended once), issued May 30, 1996, permitted to 4,510 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Ring Energy Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Red Bed, Shale Sand, Anhydrite, Lime & Sand, Dolomite & Anhydrite.
Its 3 leases have reported 213K barrels of oil and 4.88M mcf of gas since January 1993, last reporting in July 2026. The leases carry 21 wells, so these are lease totals, not this well alone.
