... Abstract This paper proposes an accurate method to represent horizontal wells in a reservoir simulation model. Conventionally, the model grids in the z-dimension coincide with the geological layers in order to honor the layer properties, resulting in non-horizontal corner point geometry grids...

... porosity, absolute permeability tensors, relative and capillary curves are associated to one or to a group of cells. For simulating fluid flow in a reservoir described by such models, several problems have to be solved: optimal gridding, upscaling of petrophysical parameters, efficient and robust linear...

... are characterized by the existence of sharp saturation and/or concentration fronts. Examples of such processes are VAPEX, in situ combustion, or water flooding of heavy oil reservoirs in presence of viscous fingering. In order to simulate correctly what happens around the fronts, small grid sizes need to be used...

... Abstract: In this work a numerical model for simulating petroleum reservoirs using the Element-based Finite Volume Method (EbFVM) is presented. The method employs unstructured grids using triangular and/or quadrilateral elements, such that complex reservoir geometries can be easily represented...

... ( Heinrich, 1987 , calls this the median grid. Forsyth (1989) applied the CVFE method to thermal reservoir simulation problems. However, all his numerical examples were for homogeneous reservoirs. Petroleum reservoir simulation involves the numerical solution of mass and/or energy conservation equations...

Consequently, the knowledge of both, block boundaries and grid point locations are required. Therefore, the distribution of grid points...

Recently an improved gridding technique was applied to model coupled geomechanics and reservoir flow in a thermal simulator. In this technique, a dual grid system consisting of separate...

... Abstract This paper reports the results of a Comparative Solution Project (CSP) which compares different flexible gridding techniques now available in some reservoir simulators. This CSP was performed by five participants and the problem posed is a 3D simulation of oil production associated...

... The reservoir engineer then gets to use the grid, with attributes, after it has been created. If the base model is created at an extremely fine scale, it could require an extremely long time for a simulation run if the model is used withough modification. In these situations, the grids are often...

... Abstract Unstructured gridding has become an important subject matter in reservoir simulation. Its flexibility of grid generation and enhanced simulation accuracy have gained popularity in reservoir simulation, especially when modeling reservoir with complex wells and faults. In this work...
