Flanagan Unit #881 (API 42-165-34949) is a well in Gaines County operated by Hilcorp Energy Company, completed April 23, 1996 and listed as shut in on the RRC schedule, shut in January 1, 2006.
The RRC has issued one drilling permit, issued February 26, 1996, permitted to 7,450 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.
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.
