McKnight M. B. #266H
Crane County · Sand Hills (Tubb) field · Producing · Horizontal
Mcknight M. B. #266H (API 42-103-35923) is a horizontal well in Crane County operated by Ring Energy Inc., completed January 31, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 1, 2011, permitted to 4,709 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 Yates, San Andres, Tubb.
Its lease has reported 6.3M barrels of oil and 26.8M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 110 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.

Each operator named on the P-4 filings for this well's lease (a gas well is its own lease), from the date its filing took effect. The P-4 is filed by lease, so a date before the well was drilled is the lease's.

"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.
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.
