Irion County · Spraberry (Trend Area) field · Shut In · Vertical
Rocker B #137F (API 42-235-35023) is a well in Irion County operated by Pioneer Natural Res. USA Inc., completed December 7, 2012 and listed as shut in on the RRC schedule, shut in February 1, 2026.
The RRC has issued one drilling permit, issued March 9, 2012, permitted to 8,690 ft.
It was permitted by Fiml Natural Resources, LLC and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Spraberry, Dean, Wolfcamp, Canyon.
Its 2 leases have reported 14.1M barrels of oil and 116M mcf of gas since April 1997, last reporting volume in August 2026. The leases carry 258 wells, so these are lease totals, not this well alone.

No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
1 log loaded from the RRC's log index, the latest received Jan 26, 2016. Resistivity. 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.
