Bayes 16 #1 (API 42-317-35196) is a well in Martin County operated by Diamondback E&P LLC, completed August 25, 2008 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 2008 and 2013, permitted to 10,630 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 8 formation tops, including Yates, Spraberry, Dean, Wolfcamp.
Its lease has reported 85.1K barrels of oil and 343K mcf of gas since August 2008, last reporting volume in August 2026. The lease carries 2 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.

"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.
