Novel permeability upscaling method using Fast Marching Method.

Highlights: [•] Dynamic upscaling is one of the key factors in reservoir simulation. [•] We proposed new dynamic method for permeability upscaling using Fast Marching Method. [•] Pressure propagation time is calculated using Fast Marching Method in a matter of seconds for multimillion cells. [•] New method is able to capture connectivity of reservoir very efficiently.
