%X The Bannan Oilfield is on its later stages of development, new discovery of oil potential is inevitably the most reliable way in sustaining its historical importance of production. A refined technique portfolio is developed to achieve a better understanding of reservoirs featuring heavily faulted, low relief, thin beds with narrow lateral extension. The problems arising from the recognition of micro-faults, tiny blocks, and micro-structures are tackled in this paper through a series of techniques as. seismic aided genetic correlation, slant well trajectory calibration, 3D seismic-well tying, wavelet domain coherence and true three-dimensional seismic based structural modeling. The spatial extension of individual sand bodies is delineated based on micro-facies analysis and lithological inversion. The study shows that the distribution of oil and gas accumulations is governed by both structural features and lithological variations. Sub-bed group structures are well developed. These micro structures, together with the fault proximity regions and the previous undiscovered oil-bearing sand bodies contribute to the major sustaining potential. The promising oil and gas flows of the 3 wells drilled based on this study are prudently advertising the remarkable value of this technical practice in extending the life of developed oil fields.
