Tracking Production Changes in a Turbidite Reservoir Using 4D Elastic Inversion

P665 TRACKING PRODUCTION CHANGES IN A TURBIDITE RESERVOIR USING 4D ELASTIC INVERSION ALAN MCINALLY 1 JOHN KUNKA 1 JENNY GARNHAM 1 TERESA REDONDO LOPEZ 1 Abstract 1 Elastic inversion of three time-lapse seismic data sets from the Nelson Field UKCS has been performed to aid in reservoir characterisation and the tracking of fluid changes within the reservoir due to production. Predicted Shear Impedance volumes and Acoustic Impedance volumes are used to delineate reservoir architecture due to their reduced fluid imprint. Poisson’s Ratio and Acoustic Impedance time-lapse volumes are combined to delineate oil and water filled sands and shales from the
