... Abstract Recent studies have shown the utility of the Fast Marching Method and the Diffusive Time of Flight for the rapid simulation and analysis of Unconventional reservoirs, where the time scale for pressure transients are long and field developments are dominated by single well performance...

... minimize this local-global coupling. In the next section, we introduce the background and the formulation of compressible diffuse source upscaling method. Diffusive Time of Flight The diffusive time of flight τ, is a generalization of the well test radius of investigation concept to describe...

... energy balance equation into a 1-D equation with a ‘diffusive time of flight’ as the spatial coordinate system. Besides the diffusive heatpropagation, Joule-Thomson effect and viscous dissipation are also considered in the model. The inner boundary of the model is carefully handled and the drainage...
