Blagrave 35b #1 (API 42-317-35526) is a well in Martin County operated by New Height Energy LLC, completed December 3, 2021 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits between 2009 and 2016, permitted to 10,557 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to New Height Energy LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.
Its lease has reported 67.6K barrels of oil and 283K mcf of gas since August 2009, last reporting volume in March 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Aug 6, 2010. 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.
