Ross #4
Reagan County · Spraberry (Trend Area) field · Shut In · Vertical
Ross #4 (API 42-383-34149) is a well in Reagan County operated by Diamondback E&P LLC, completed November 25, 1991 and listed as shut in on the RRC schedule, shut in February 1, 2026.
The RRC has issued one drilling permit, issued November 6, 1991, permitted to 8,110 ft.
It was permitted by Stephens, Autry C. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.
Its lease has reported 78.2K barrels of oil and 1.01M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 3 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.
