One goal for oil fields of the future is acquiring continuous and on-demand data as required for fieldand reservoir management.Synthetic time-lapse production methods are becoming a way of providingthis information at and away from wells.Time-lapse production log data acquired over oil fields is usedto monitor water sweep in the reservoir.Production logs provide a direct measure of the fluid flowingdownhole and detect the unwanted fluid entries.In field applications,this advanced scanning of fluidprofiling successfully derisked several infill well locations and identified new workover candidates anddrilling opportunities in the fields.Synthetic time-lapse production logging is a useful complement to understanding reservoir heterogeneityand complexity through tailored synthetic and real data integration.A computer-based workflow hasbeen developed to automate the downhole production flow profile.Production performance of the well isassessed,considering the dynamic time-lapse logging data.A synthetic flow profile is constructed to showthe change in water production signature,and the well is further examined if it undergoes remedial actions.Reservoir characterization is a continuous process during the life of the oil field.As new data are available,the model is updated and contains more details.The incorporation of all data allows increased accuracy andreduced uncertainty in characterizing the reservoir.The proposed methodology requires the acquisition of dynamic production logging data to establish asolid workflow and validate the model.Uncertainty can be eliminated with the acquisition of additionalproduction logs.Recommendations for improvement of the current well condition can be made to reducethe well water cut and improve oil production from the well.Consequently,well classification and candidateselection for workover can be achieved.The results of this work demonstrate the strength of applyingmultidisciplinary team efforts to develop automated workflows that are relevant to reservoir and productionengineers who deal with complex reservoirs with numerous wells.
