Well log data from deep parts of the 5 wells located in Z-Field of Chad basin were used in characterization of available reservoir sands. Well log data used include, sonic, gamma rays, matrix density and resistivity logs. A computer software (PETREL) was used and the wireline log data were studied to characterize the porosity, water saturation, volume of shale of the Z-Field reservoir. The thickness of each sand unit varied between 112 and 309 m, in reservoir 1 and between 128 and 259 m, in reservoir 2. The average water saturation (SW) of reservoirs 1 and 2 were 0.51 and 0.48 m, respectively. Similarly, the average hydrocarbon saturation values for reservoirs 1 and 2 were 26.99 and ........................................
