Hemphill County · Mendota NW. (Granite Wash) field · Producing · Vertical
Isaacs 1 #4 (API 42-211-32233) is a well in Hemphill County operated by Bce-Mach Iii LLC, completed August 19, 1997 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits (amended once) between 1997 and 2014, permitted to 10,500 ft.
It was permitted by Cimarex Energy CO. and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Brown Dolomite, Topeka, Douglas, Tonkawa.
Its 3 leases have reported 99.3K barrels of oil and 472K mcf of gas since August 1997, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
