Zain 26 #6 (API 42-461-39128) is a well in Upton County operated by Pioneer Natural Res. USA Inc., completed May 20, 2014 and listed as shut in on the RRC schedule, shut in April 1, 2026.
The RRC has issued one drilling permit (amended once), issued December 10, 2013, permitted to 11,826 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 10 formation tops, including San Andres, Spraberry, Wolfcamp, Strawn.
Its lease has reported 1.98M barrels of oil and 8.25M mcf of gas since May 2013, last reporting volume in April 2026. The lease carries 13 wells, so these are lease totals, not this well alone.

Completion filings
W-2 and G-1 reports on record in the RRC wellbore file, newest first. The suffix identifies the wellbore or completion event. The record date is the RRC's own date on the record, not the day the report was filed: 462,034 of the state's filings carry 1984-01-12. About these reports →

Well logs
1 log loaded from the RRC's log index, the latest received May 1, 2017. 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.
