Chaps #1 (API 42-329-35609) is a plugged well in Midland County, plugged March 16, 2022, last operated by Pioneer Natural Res. USA Inc..
The RRC has issued one drilling permit, issued September 13, 2006, permitted to 12,000 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Clear Fork, Spraberry, Dean, Wolfcamp.
Its lease has reported 238K barrels of oil and 507K mcf of gas since March 2009, with no volume in the three years through August 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

Surface location
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.

Wells named Chaps
Pioneer Natural Res. USA Inc.'s other wells filed under this lease name in Midland County, newest permit first. The RRC gives a gas well its own lease number, so the name is what joins the wells of a unit.

"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.
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.
