Hasel6 #2 (API 42-461-37779) is a plugged well in Upton County, plugged April 29, 2026, last operated by Diamondback E&P LLC.
The RRC has issued one drilling permit, issued December 8, 2011, permitted to 10,300 ft.
It was permitted by Cog Operating LLC and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 5 formation tops, including T. Clearfork, T. Spraberry, T. Dean, T. Wolfcamp.
Its lease has reported 101K barrels of oil and 241K mcf of gas since November 2006, last reporting volume in February 2025. 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 Mar 31, 2015. 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.
