Well Logging Analysis of the Devonian Awaynat Wanin Formation (F3) “B” in A37-NC169a well, Al Wafa field, Ghadames Basin, Libya

Abstract

The Ghadames basin represents the second main basin in oil production in Libya. Al Wafa Field is one of the oil and gas producer in Ghadames basin. This work aims to evaluate the sandstone of Aouinet Uennin Formation (F3) “B” in A37-NC169a well, Al Wafa field, Ghadames Basin, Libya. The applied methods in this research encompasses the qualitative and quantitative well logging evaluation for the entire sandstone (F3) “B”-sand level) of the Awaynat Wanin Formation in A37-NC169a well. The analysis of the well logging data, the examined sandstones exhibit high potentiality for hydrocarbon production in its topmost part (level 1) with 54 ft thick. This reservoir displays high hydrocarbon saturation values fluctuates between 80-90%, porosity ranges between 5-15%, low Bulk Volume of Water 0.01and 0.02, irreducible water saturation equals 22 %, and permeability nearly 7 MD. Accordingly, this study highlights the oil potentiality of the sandstones of the Awaynat Wanin Formation (F3) “B” for further exploration purposes in Al Wafa field and the surrounding fields within the Ghadames Basin.
