Patent ID: 8612194

Claim:
A method of updating a subterranean model, comprising: providing an initial subterranean model; based at least in part on the initial subterranean model, predicting changes of subterranean parameters using a reservoir simulator, wherein predicting changes of the subterranean parameters comprises predicting changes due to development of a reservoir in a subterranean structure; computing, by a computer, electromagnetic data representing characteristics of the subterranean structure according to the predicted changes of the subterranean parameters, wherein computing the electromagnetic data according to the predicted changes of the subterranean parameters comprises converting, using a rock physics model, the predicted changes of the subterranean structure to electrical properties associated with the subterranean structure, and computing the electromagnetic data from the electrical properties using electromagnetic modeling; and modifying the initial subterranean model to provide an updated subterranean model based at least in part on comparing the computed electromagnetic data with observed electromagnetic data.
