Cross 36 #1 (API 42-317-34709) is a well in Martin County operated by Diamondback E&P LLC, completed March 21, 2022 and listed as shut in on the RRC schedule, shut in August 1, 2023.
The RRC has issued 2 drilling permits (amended once) between 2006 and 2016, permitted to 10,780 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 7 formation tops, including Yates, San Andres, Spraberry, Dean.
Its lease has reported 109K barrels of oil and 218K mcf of gas since January 2007, with no volume in the three years through August 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

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 Sep 1, 2009. 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.
