Tubb J. B. Etal #28 (API 42-103-31918) is a well in Crane County operated by Ring Energy Inc., completed October 9, 1978.
The RRC has issued 3 drilling permits between 1978 and 2021, permitted to 4,850 ft.
It was permitted by Stronghold Energy II Oper, LLC and has since transferred to Ring Energy Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Holt, McKnight, Glorieta, Clear Fork.
Its 2 leases have reported 227K barrels of oil and 1.63M mcf of gas since January 1993, last reporting in July 2026. The leases carry 17 wells, so these are lease totals, not this well alone.
