Shut in

Pecos County · Brown & Thorp East (Tubb) field · Shut In · Vertical

Brown & Thorp Waterflood Unit #13 (API 42-371-34040) is a well in Pecos County operated by Greenstone Energy LLC, completed December 22, 1990 and listed as shut in on the RRC schedule, shut in August 1, 2016.

The RRC has issued one drilling permit, issued October 8, 1982, permitted to 3,200 ft.

It was permitted by Hcw Exploration, Inc. and has since transferred to Greenstone Energy LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Rustler, Yates, Queen, San Andres.

Its 2 leases have reported 1.06M barrels of oil and 59 mcf of gas since January 1993, last reporting volume in March 2026. The leases carry 60 wells, so these are lease totals, not this well alone.
