Abstract
4D time lapse seismic is one of the most efficient methods to evaluate spatial changes in reservoir<br>properties (fluid saturation, pressure, salinities changes) during field production. The 4D signal<br>obtained from time lapse seismic can be used in two ways: qualitatively (in a static way): 4D<br>extensions limits are interpreted, up-scaled and can lead to manual changes of static and dynamic<br>properties inside the reservoir model or quantitatively (in a dynamic manner) by trying to match<br>changes in dynamic parameters estimated from fluid flow simulator with 4D signal measured from<br>seismic time lapse. Both alternatives are well illustrated in Castro et al (2009).
