Separation Of Pressure And Saturation Effects Using Avo 4D In Marlim Field
2009
Using the method introduced by Landro (2001), it has been possible to study the pressure and saturation changes induced by production in the Marlim field, figure 1. This methodology does not make any assumption about production, requiring only petrophysical and seismic data covering the field of interest. Maps representing pressure and saturation changes are presented and also a section over one well, showing how these anomalies can be compared with flow simulator prediction. The main result obtained is a better understanding of the mechanism by which water saturation and effective pressure changes are created during field production.
