Chambers County · Barbers Hill field · Vertical
Winfree O. K. #8 (API 42-071-31648) is a plugged well in Chambers County, plugged November 10, 2011, last operated by Lone Star Ngl Mont Belvieu LP.
The RRC has issued one drilling permit, issued November 14, 1984, permitted to 7,100 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Lone Star Ngl Mont Belvieu LP on the wellbore schedule.
Completion filings report one formation top, including Miocene (undifferentiated).
Its lease has reported 64.1K barrels of oil and 14.8K mcf of gas since January 1993, last reporting in August 2012. The lease carries 2 wells, so these are lease totals, not this well alone.
