Merchant Unit #4104K
Reagan County · Spraberry (Trend Area) field · Shut In · Vertical
Merchant Unit #4104K (API 42-383-34549) is a well in Reagan County operated by Pioneer Natural Res. USA Inc., completed July 16, 1996 and listed as shut in on the RRC schedule, shut in February 1, 2021.
The RRC has issued one drilling permit, issued March 13, 1996, permitted to 8,250 ft.
It was permitted by Parker & Parsley Development L.P and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 2 formation tops, including Spraberry, Dean.
Its lease has reported 6.36M barrels of oil and 36.8M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 200 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.
