.... Abstract The Fast Marching Method (FMM)-based rapid flow simulation has been shown to accelerate simulation efficiency by orders of magnitude by transforming 3-D simulation to equivalent 1-D simulation using the concept of the Diffusive-Time-of-Flight (DTOF). However, the 1-D transformation does...

...) based rapid simulation has offered significant speed-up, commonly two to three orders of magnitude, for modeling unconventional reservoirs. The key concept here is a coordinate transformation from 3-D to 1-D using the Diffusive-Time-of-Flight (DTOF) as the spatial coordinate. The DTOF represents...

... is to partition the reservoir model into independent sub-domains associated with individual wells based on the Diffusive Time of Flight (DTOF) computed as solution to the Eikonal equation using the FMM. Multiphase production rates are then computed for each well by utilizing the DTOF as spatial coordinate...

... simulation approach is based on a high frequency asymptotic solution of the diffusivity equation in heterogeneous and fractured reservoirs. The high frequency solution leads to the Eikonal equation which is solved for a ‘diffusive time of flight’ (DTOF) that governs the propagation of the ‘pressure front...
