abstract = {<p style="text-align: justify;">Numerical solution of time-lapse seismic monitoring problems can be challenging due to the presence of finely layered reservoirs. Repetitive wave modeling using fine layered meshes also adds more computational cost. Conventional approaches
such as finite difference and finite element methods may be prohibitively expensive if
the whole domain is discretized with the cells corresponding to the grid in the reservoir subdomain. A common approach in this case is to use homogenization techniques
to upscale properties of subsurface media and assign the background properties to
coarser grid; however, inappropriate application of upscaling might result in a distortion of the model, which hinders accurate monitoring of the fluid change in subsurface.
In this work, we instead investigate capabilities of a multiscale method that can deal
with fine scale heterogeneities of the reservoir layer and more coarsely meshed rock
properties in the surrounding domains in the same fashion. To address the 3-D wave
problems, we also demonstrate how the multiscale wave modeling technique can detect the changes caused by fluid movement while the hydrocarbon production activity
proceeds.</p>},
