Martin County · Spraberry (Trend Area) field · Producing · Vertical
Glass G. W. B #11 (API 42-317-34919) is a well in Martin County operated by Cutbow Operating LLC, completed December 14, 2007 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 22, 2007, permitted to 11,015 ft.
It was permitted by Thompson, J. Cleo and has since transferred to Cutbow Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Yates, Spraberry, Dean, Wolfcamp.
Its 2 leases have reported 1.16M barrels of oil and 2.48M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 22 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Oct 14, 2008. 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.
