... adaptive gridding with two and six levels of refinements in 2D is used to provide high resolution and to increase the computational efficiency. Non-isothermal model provides more accurate predictions in the vicinity of the injection wells where the temperature changes significantly with the injection...

... Abstract The numerical simulations in hydraulic fracturing will significantly become more efficient by the use of adaptive refinements. Only the areas where the fracture propagates need fine mesh resolution. This study presents a method for performing dynamic adaptive refinements in hydraulic...

In the most complex case, it is coupled with the phase field method to model nucleation and branching of non...

There are on-going R&D efforts on applying unstructured grids to better represent the near-well flow in reservoir simulation, but their applications are mainly in single-well study or sector modeling with a few wells. Some...

... are known but intracell velocities need to be interpolated and streamline trajectories calculated. Our proposed solution relies upon a refinement of the polygonal cells and provides a velocity field which is locally conservative, allows analytic calculation of the streamline trajectories, and does...

.... To reconcile data with model resolution during history matching, we first use the coarsest scale basis functions to identify the large scale variability. Additional smaller-scale basis elements are then adaptively incorporated to successively refine the model to a level supported by data resolution. During...

... is in identifying where and when to adjust the grid. This paper presents a semi-implicit scheme, that allows for the evaluation of grid adaption criteria within a time step, and guarantees that grid refinements occur where the fronts have propagated at the end of each time step. No assumptions on front movement...

During run-time, we refine the grid locally, as needed, to accurately resolve saturation fronts, and coarsen once the front passes. We do not employ...

This is particularly useful when faults or local grid refinements (LGRs) are used in the simulation grids. MPFA ideas have previously been considered for faults in [ 22 , 23...
