Bloodworth 139 #8
Sutton County · Sawyer (Canyon) field · Vertical
Bloodworth 139 #8 (API 42-435-34961) is a well in Sutton County operated by Enervest Operating L.L.C., completed August 5, 1999.
The RRC has issued 2 drilling permits between 1999 and 2013, permitted to 8,400 ft.
It was permitted by Highmount Expl & Prod Texas LLC and has since transferred to Enervest Operating L.L.C. on the wellbore schedule.
Completion filings report 5 formation tops, including Base Cretaceous (marker), Leonard, Wolfcamp, Canyon.
Its 2 leases have reported 18.1K barrels of oil and 404K mcf of gas since August 1999, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
