Glass G.W. B #16
Martin County · Spraberry (Trend Area) field · Shut In · Vertical
Glass G.W. B #16 (API 42-317-34914) is a well in Martin County operated by Cog Operating LLC, completed November 1, 2007 and listed as shut in on the RRC schedule, shut in April 1, 2026.
The RRC has issued one drilling permit, issued May 17, 2007, permitted to 10,742 ft.
It was permitted by Thompson, J. Cleo and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Yates, Spraberry, Dean, Wolfcamp.
Its lease has reported 1.04M barrels of oil and 2M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 20 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.

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 Oct 10, 2008. Density, Neutron, 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.
