Using Time-lapse Saturation-change Data to Update Flow Models

Time-lapse analysis and interpretation

Time-lapse seismic data may be used to define the fluid-flow characteristics of the reservoir and improve flow models. The technique uses time-lapse seismic methods, and allows asset teams to observe the dynamic processes in and around the reservoir, making the development and production stages more successful by placing wells more effectively.

In this example (right), the regions of injected water from the analysis were input into the ECLIPSE FrontSim streamline simulator to help identify the connectivity between injector wells and producer wells. Streamlines indicate the fluid-migration path. The density of the streamlines is proportional to flow rates, and saturations are color-coded from high water saturation (blue) to high oil saturation (red). The blackened area is a visualization effect to enable the examination of flow paths. As expected, streamlines start at injector wells and end in zones with high water saturation.
