McKnight M. B. #188
Crane County · Running W N. (Holt) field · Producing · Vertical
Mcknight M. B. #188 (API 42-103-34728) is a well in Crane County operated by Ring Energy Inc., completed August 30, 2019 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits between 2000 and 2006, permitted to 6,203 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Ring Energy Inc. on the wellbore schedule.
Completion filings report 15 formation tops, including Rustler, Yates, Seven Rivers, Queen.
Its 3 leases have reported 3.91M barrels of oil and 20.9M mcf of gas since January 1993, last reporting in July 2026. The leases carry 161 wells, so these are lease totals, not this well alone.
