Improving production history matching using time‐lapse seismic data

This paper presents a new approach to reservoir management by integrating time‐lapse seismic data with production data. The basic steps involve combining the seismic data from the base survey with log and production data to build an initial reservoir model which is run forward to the time of the repeat seismic survey. The output from this simulation was then converted to a synthetic monitor survey, using Gassmann’s equations and a simple convolutional approach. Finally, the differences between the synthetic and real seismic time‐lapse data are minimized using an optimization algorithm.
