    Abstract

    Quantitative estimation of dynamic reservoir properties from time-lapse seismic is becoming increasingly widespread. In compacting reservoirs however, the 4D seismic signal is complex due to stress and strain redistribution in reservoir and non-reservoir rocks. Several authors have reported observing measurable time-shifts in the overburden on time-lapse seismic data. A method for using these overburden time-lapse time-shifts to invert for reservoir pressure change is presented. This method requires minimal constraints and is computationally fast, when compared with more complex geomechanical modelling. Results are shown after the application of the technique to the Genesis Field in the Gulf of Mexico.
