Scharbauer Ranch #81 (API 42-317-38129) is a well in Martin County operated by Cutbow Operating LLC, completed February 18, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 19, 2012, permitted to 11,951 ft.
It was permitted by Pioneer Natural Res. USA, Inc. and has since transferred to Cutbow Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Spraberry, Dean, Wolfcamp, Strawn.
Its 2 leases have reported 23.7M barrels of oil and 39.5M mcf of gas since May 2005, last reporting volume in April 2026. The leases carry 187 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Feb 18, 2014. 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.
