Not one formation; the well must be completed in one of them, and no target formation is stated.

Dusek 45 #1 (API 42-461-37733) is a well in Upton County operated by Pioneer Natural Res. USA Inc., completed February 20, 2012 and listed as shut in on the RRC schedule, shut in February 1, 2020.

The RRC has issued one drilling permit (amended once), issued November 4, 2011, permitted to 12,000 ft.

It was permitted by Parsley Energy Operations, LLC and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Strawn, Atoka.

Its lease has reported 519K barrels of oil and 3.79M mcf of gas since February 2012, last reporting volume in March 2026. The lease carries 12 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

1 log loaded from the RRC's log index, the latest received Feb 9, 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.
