Reagan County · Spraberry (Trend Area) R 40 Exc field · Shut In · Horizontal
Rocker B 20-21 #31HS (API 42-383-39485) is a horizontal well in Reagan County operated by Permian Resources Operating LLC, completed March 29, 2018 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued September 16, 2015, permitted to 7,610 ft.
It was permitted by American Energy-Perm Basin, LLC and has since transferred to Permian Resources Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Grayburg, San Andres, Spraberry, Jo Mill.
Its 2 leases have reported 2.51M barrels of oil and 35.3M mcf of gas since December 2013, last reporting volume in April 2026. The leases carry 62 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, 1 of them with a digital LAS file, the latest received Dec 16, 2021. Gamma ray. 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.
