PESA WA June Technical lunch talk – Monitoring of the reservoir pressure & saturation changes using Extended Elastic Impedance from time lapse seismic data: Enfield Field
Presented by Sergey Shevchenko. This presentation demonstrates how the Extended Elastic Impedance (EEI) concept has been used as a method for reservoir monitoring, calculating changes in pressure and saturation in a producing reservoir by applying EEI to time-lapse seismic data. The method uses time-lapse seismic difference data rotated to specific EEI χ angles which are optimised for the changes expected in a given reservoir.
