Seismic waves in multiscale media: impact of cavernous/fractured reservoirs

Reporter: Tcheverda V.

     In order to simulate interaction of seismic waves with cavernous/fractured reservoirs the finite-difference technique based on locally refined in time and space grids is used. The need to use these grids is due to essentially different scales of heterogeneities in the reference medium and in the reservoir. Parallel computations are organized on the base of Domain Decomposition of the target area into elementary subdomains in the both reference medium (coarse grid) and reservoir (fine grid). Each subdomain is assigned to its Processor Unit which form two groups - for reference medium and for reservoir. The data exchange between PU within the same group is performed in a standard manner - by nonblocking iSend/iReceive commands. The data exchange between two clusters is done simultaneously with coupling of coarse and fine grids and is controlled by specially designated PU.
      Results of numerical simulation for a realistic model of the carbonate collector are presented and discussed.
