University Sec. 10 #1
Upton County · Spraberry (Trend Area) field · Vertical
University Sec. 10 #1 (API 42-461-31475) is a plugged well in Upton County, plugged May 28, 2010, last operated by Atlas Operating LLC.
The RRC has issued one drilling permit, issued August 31, 1979, permitted to 8,500 ft.
It was permitted by Palo-Placer and has since transferred to Atlas Operating LLC on the wellbore schedule.
Its lease has reported 20.7K barrels of oil and 26.1K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Permitted by Palo-Placer; the EWA schedule now lists a different operator.

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.
