The Middle Devonian Aouinet Ouenine F3 Sandston Member represent the main reservoir, in Al Wafa Field-NC169a, which is located in southwest part Ghadames Basin. The reservoir distribution and it is quality in the area is not well defined.
In order to better understand the reservoir potential and its distribution, geophysical and petrophysical analysis were carried out, the data from fifty five wells and 3D seismic data were used, twenty nine wells were selected for detailed petrophysical analysis.
The results revealed that the reservoir has lateral changes in terms of lithology and thickness, the F3 sand mapped with confident by using the seismic attribute volume in conjunction with the seismic interpretation stack volume, the lithology change from sandstone to shaly sand toward the south due to the sea level changes.
The petrophysical analysis results show that Aouinet-Ouenine F3 sandstone reservoir quality is variable, net pay thickness is ranges from one foot to 101 feet, Average porosity is 12.5 % and average water saturation is 16 %, due to the facies changes. The study area can be classified to high, moderate and low risk in terms of the reservoir quality
