Abstract
Adopting the Kostrov methodology we determine a strain rate tensor for any grid area in 4D by summing source moment tensors of microseismic events. The predicted strain rate tensor is used to provide a priori constraints on the style and direction of the observed deformations. This is a hybrid method that is shown to reduce uncertainties of geomechanically modeled displacement field in a depleting reservoir during the monitoring period. The improved microseismic-to-geomechanics link is seen as a key step to reservoir modeling and to the future realization of reservoir management value from this technology.
