Why use time-lapse seismic monitoring?
Although global reserves figures continue to rise, so too does consumption and population. At some stage, a fundamental resource limit will be reached, and there will be a supply and demand discontinuity. Since hydrocarbon recovery from existing reservoirs is generally low, the most significant impact on supply is likely to be made by increased oil recovery methods.
In reservoirs, information between wells is scarce, and seismic monitoring techniques have tremendous potential to provide such lateral data provided there is a clear link between seismic observables and reservoir variables such as fluids, pressure or temperature.
