Paper Number: SPE-203917-MS
... have examined the PIML method in terms of their reliability and capability to handle reservoir engineering boundary conditions, fractures, source and sink terms. Here we explored the potential of PIML for modelling 2D single phase, incompressible, and steady state fluid flow in porous media. The main...

... of the results. The sector model requires only 20 cores. To perform this workflow, the engineer needs only to add the definition of the sector to the model, and the type of boundary condition to apply. As a square is chosen here, which passes through all layers of the model, the stacked contour S in Equation (2...
