Mcknight M. B. #506H (API 42-103-36110) is a horizontal well in Crane County operated by Ring Energy Inc., completed September 18, 2021 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 2012 and 2021, permitted to 5,020 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 San Andres, Holt, Clear Fork, Tubb.
Its 2 leases have reported 3.81M barrels of oil and 20.5M mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The leases carry 153 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
3 logs loaded from the RRC's log index, the latest received May 24, 2016. Density, Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
