Johan Sverdrup - application of advanced seismic imaging and modelling to reduce uncertainty in reservoir monitoring

Permanent reservoir monitoring (PRM) systems provide frequent, highly repeatable data shortly after acquisition. Obtained fresh time-lapse information is routinely used to observe fluid front movement and correlate to production data. PRM time lapse observations are a natural input to integrate with the Fast Model Update (FMU) to condition reservoir model. With good control on input data quality and notorious attention to data limitations we can assess uncertainty and understand risks inherent in the acquired seismic data. Application of advanced seismic imaging and modelling solutions allows to compensate for geological challenges and obtain insights into 3D and 4D interpretability at the target. High quality data obtained from the PRM systems coupled with an assessment of interpretation uncertainty provides valuable support to reservoir management decisions.
