Brown & Thorp Waterflood Unit #1818 (API 42-371-36319) is a well in Pecos County operated by Greenstone Energy LLC, completed November 6, 1991 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued September 4, 1991, permitted to 3,200 ft.
It was permitted by Parker & Parsley Development CO. and has since transferred to Greenstone Energy LLC on the wellbore schedule.
Completion filings report one formation top, including Clear Fork.
Its lease has reported 1.06M barrels of oil and 59 mcf of gas since January 1993, last reporting in July 2026. The lease carries 60 wells, so these are lease totals, not this well alone.
