Comparing Time-Lapse Seismic and Reservoir Model Predictions in Producing Oil and Gas Fields

Abstract

A-24 COMPARING TIME-LAPSE SEISMIC AND RESERVOIR MODEL PREDICTIONS IN PRODUCING OIL AND GAS FIELDS Summary The main value of time-lapse seismic is the additional information to constrain or update a model of the reservoir. Knowledge of reservoir connectivity flow barriers or bypassed hydrocarbons is the kind of information we hope to get from time-lapse data in order to optimize reservoir investment decisions. Though reservoir models are in general constrained by history matching with well production data the solution is most often not unique as the amount of well data is rather sparse compared to time-lapse seismic. 1 A key step
