Mcknight M. B. #140 (API 42-103-33099) is a well in Crane County operated by Ring Energy Inc., completed March 2, 1983.

The RRC has issued 2 drilling permits between 1983 and 2005, permitted to 3,790 ft.

It was permitted by Devon Energy Production CO, L.P. and has since transferred to Ring Energy Inc. on the wellbore schedule.

Its 2 leases have reported 1.65M barrels of oil and 12.8M mcf of gas since January 1993, last reporting in July 2026. The leases carry 134 wells, so these are lease totals, not this well alone.
