Seismic imaging of reservoir flow properties: Resolving water influx and reservoir permeability
Methods for geophysical model assessment, in particuale the computation of model parameter resolution, indicate the value and the limitations of time-lapse data in estimating reservoir flow properties. A trajectory-based method for computing sensitivities provides an effective means to compute model...

Methods for geophysical model assessment, in particuale the computation of model parameter resolution, indicate the value and the limitations of time-lapse data in estimating reservoir flow properties. A trajectory-based method for computing sensitivities provides an effective means to compute model parameter resolutions. We examine the common situation in which water encroaches into a resrvoir from below, as due to the upward movement of an oil-water contact. Using straight-forward techniques we find that, by inclusing reflections off the top and bottom of a reservoir tens of meters thick, we can infer reservoir permeability based upon time-lapse data. We find that, for the case of water influx from below, using multiple time-lapse 'snapshots' does not necessarily improve the resolution of reservoir permeability. An application to time-lapse data from the Norne field illustrates that we can resolve the permeability near a producing well using reflections from three interfaces associated with the reservoir. |
