This research work focuses attention on the Reservoir Characterization of a hydrocarbon bearing sand in ‘Eme’ field of the Niger Delta. The environment of deposition is examined and the type produced as a model of the sub-surface reservoir. To achieve this, an integrated analysis of cores from wells, as well as biostratigraphic data and wireline logs of the D7.000sand were used for the study. The D7.000 sand of study comprises one major depositional sequence. From the petrophysical study carried out through use of composite logs, amalgamated sand is found to be more porous and more permeable than the tidal channel. Core analysis revealed the existence of ten lithofacies. These lithofacies are grouped into facies association in a vertical sequence with a genetic significance using primary structures and shape of wireline logs.
