Chambers County · Barbers Hill field · Vertical
Winfree O. K. #3A (API 42-071-31541) is a plugged well in Chambers County, plugged October 25, 2011, last operated by Lone Star Ngl Mont Belvieu LP.
The RRC has issued one drilling permit, issued March 19, 1984, permitted to 3,000 ft.
It was permitted by E-Tex Oil CO. and has since transferred to Lone Star Ngl Mont Belvieu LP on the wellbore schedule.
Its lease has reported 818 barrels of oil and 20 mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
