UL Digger #10 (API 42-003-41613) is a plugged well in Andrews County, plugged September 10, 2017, last operated by Diamondback E&P LLC.
The RRC has issued 2 drilling permits between 2010 and 2011, permitted to 10,900 ft.
It was permitted by Windsor Permian LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Clear Fork, Spraberry, Strawn.
Its 2 leases have reported 677K barrels of oil and 1.03M mcf of gas since December 2009, last reporting volume in April 2026. The leases carry 14 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Nov 3, 2011. 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.
