Carper 12 #8
Sterling County · William Fuller (Lo. Clearfork) field · Shut IN · Vertical
Carper 12 #8 (API 42-431-32597) is a well in Sterling County operated by Vision Exploration LLC, completed August 10, 2012 and listed as shut in on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1992 and 2001, permitted to 7,800 ft.
It was permitted by Range Production Company and has since transferred to Vision Exploration LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Clear Fork, Wolfcamp, Cisco, Canyon.
Its 2 leases have reported 156 barrels of oil and 269K mcf of gas since February 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
