Workflows for Quantitative 4D Seismic Data Integration: A Case Study.

This paper describes the full cycle of 4D seismic data integration comprised of workflows related to 4D data analysis, quality<br>control of reservoir models and reservoir model updating using both 4D seismic and well production data. These workflows<br>are applied to a deepwater field, where high quality 4D seismic data is available. In the first step, we analyze 4D seismic data<br>and extract multiple attributes to image changes in reservoir properties. Next, we apply different workflows which link 4D<br>seismic data with the reservoir model. Finally, we update the reservoir model automatically by simultaneously honoring the<br>4D seismic and well production data. We use a novel approach which incorporates 4D seismic amplitude differences without<br>explicitly modeling the full physics in a joint history matching workflow.
