Williams #5 (API 42-383-36574) is a well in Reagan County operated by Diamondback E&P LLC, completed April 2, 2010 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 6, 2009, permitted to 8,518 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Clear Fork, Spraberry, Wolfcamp.
Its lease has reported 156K barrels of oil and 1.45M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 6 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.
Wells nearby
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.
