McKnight M.B. #505H
Crane County · Sand Hills (Wolfcamp) field · Shut In · Horizontal
Mcknight M.B. #505H (API 42-103-36109) is a horizontal well in Crane County operated by Ring Energy Inc., completed May 24, 2013 and listed as shut in on the RRC schedule, shut in March 1, 2025.
The RRC has issued one drilling permit, issued December 27, 2012, permitted to 5,957 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 3 formation tops, including Tubb, Wichita-Albany, Wolfcamp.
Its lease has reported 1.82M barrels of oil and 8.76M mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 43 wells, so these are lease totals, not this well alone.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
1 log loaded from the RRC's log index, the latest received Nov 3, 2014. Resistivity. 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.
