Abstract
In order to incorporate the size of reservoir grids into the seismic frequency scale, the standard Backus averaging method is used for upscaling. We propose to extend the Backus averaging method for the low-frequency case and introduce the dispersive Backus model using the Baker-Campbell-Hausdorff (BCH) series. The accurate description of velocity dispersion for effective medium is very important in seismic modelling and inversion of seismic data into effective reservoir properties.
