Dawson County · Welch field · Producing · Vertical
Welch Northeast Unit #1605 (API 42-115-32443) is a well in Dawson County operated by Three Span Oil & Gas Inc., completed October 15, 1987 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 19, 1987, permitted to 4,987 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Three Span Oil & Gas Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Rustler, Yates, San Andres.
Its lease has reported 726K barrels of oil and 14.5K mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 41 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.
