Gaines County · Flanagan (Clearfork Cons.) field · Producing · Horizontal · Sidetrack
Flanagan Unit #871 (API 42-165-34748) is a horizontal well in Gaines County operated by Hilcorp Energy Company, completed June 28, 1996 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 1994 and 1996, permitted to 9,270 ft.
It was permitted by Shell Western E&P Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 6 formation tops, including Rustler, Yates, San Andres, Glorieta.
Its lease has reported 15.9M barrels of oil and 5.03M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 220 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.
