McKnight M.B. #233
Crane County · Sand Hills (Wolfcamp) field · Vertical
Mcknight M.B. #233 (API 42-103-35547) is a well in Crane County operated by Ring Energy Inc., completed July 2, 2008.
The RRC has issued 2 drilling permits between 2008 and 2021, permitted to 6,500 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 7 formation tops, including San Andres, Holt, Clear Fork, Tubb.
Its 3 leases have reported 10.1M barrels of oil and 47.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 263 wells, so these are lease totals, not this well alone.
