Integrating Time-Lapse 3D (4D) Seismic Data with Reservoir Simulators

F-02 INTEGRATING TIME-LAPSE 3D (4D) SEISMIC DATA WITH RESERVOIR SIMULATORS J. WAGGONER WesternGeco 455 London Road Isleworth Midd'x TW7 5AA UK Abstract Time-lapse 3D or 4D seismic is gaining acceptance as a valuable element of effective reservoir management. When it works 4D seismic can reveal undrained reservoir compartments identify flood front positions and assist the evaluation of potential drilling targets. These are examples of what this presentation refers to as Visual Interpretations of 4D results. Assuming that a 4D result has been obtained (see for example Waggoner 1998) this presentation focuses on the different ways that the 4D result can
