F-31 SEQUENCE STRATIGRAPHY AND SEISMIC IMPEDANCE – A NEW APPROACH TO RESERVOIR CHARACTERISATION Abstract 1 In reservoir characterisation we strive to develop a unified model of the reservoir that integrates the available seismic well log geologic and engineering data. Such models are best derived in the context of a sequence stratigraphic framework. A methodology is presented which uses sequence stratigraphy to accurately tie well log and seismic data within a realistic geological context. An impedance volume is then generated that fully integrates the geological petrophysical and engineering data and which can permit interpretation at the flow unit scale. Such reservoir
