Integrated 4D quantitative interpretation for assisted reservoir model updating

Time-lapse (4D) seismic has repeatedly demonstrated its value in impacting the reservoir model by directly measuring the state of the reservoir. The objective of its use in reservoir modeling is typically to relate the 4D seismic response with a given noise level to changes in reservoir properties, such as effective stress, saturations and reservoir geometry. The current work outlines the use of quantitative interpretation in a 4D context where information from different physical domains are integrated. Examples with real data illustrate the impact on reservoir model updating.
