The scale up technique proceeds by first identifying portions of the fine scale reservoir description which could potentially lead to high fluid velocities, typically regions of connected, high permeability. These regions are then modeled in detail while the remainder of the domain is coarsened using a general numerical technique for the calculation of effective permeability. The overall scale up method is applied to the cross sectional simulation of three actual fields. Waterflood, steamflood and miscible flood recovery processes are considered. In all these cases, the scale up technique is shown to give coarsened reservoir descriptions which provide simulation results in very good agreement with those of the detailed reservoir descriptions. For these simulations, speedups in computation times, for the coarsened models relative to their fine grid counterparts, range from a factor of 10 to a factor of 200.IntroductionStudies documenting the effects of fine scale heterogenous reservoir displacement processes have appeared with increasing frequency over the past several years. One approach to represent such effects in reservoir simulation models is to generate highly detailed geostatistical realizations of rock properties and use these as input to reservoir simulators. However, due to the high level of detail typically included in these geostatistical descriptions, the computational requirements for reservoir simulation can become prohibitive. For example, a detailed three dimensional geostatistical model may contain 10 to 10 grid blocks, while a typical high performance workstation can realistically accommodate reservoir simulation models of only 10 to 10 grid blocks, depending on the type of simulation. Thus, to develop simulation models containing 10 to 10 grid blocks that are representative of highly detailed geologic models containing 10 to 10 grid blocks, a scale up of about a factor of 100 is required. This corresponds to a coarsening of about a factor of 4 or 5 in each linear dimension.We have recently developed and applied a general methodology for the scale up of heterogeneous reservoir cross sections that achieves this degree of coarsening in two coordinate directions. Given a detailed description of a reservoir cross section, the method is designed to generate a coarsened model that will provide predictions for the global pressure - flow rate behavior of the reservoir, the breakthrough characteristics of the displacing fluid and the overall fractional flow curves of the various reservoir fluids, in close agreement with simulation results from the original detailed description. The method proceeds by first identifying regions of potentially high fluid velocity, which are modeled in detail. Then, the bulk of the domain is coarsened using a general technique for the calculation of effective permeability.P. 365^ Keywords: durlofsky, flow in porous media, coarsened model, displacement process, fine scale model, fluid dynamics, society of petroleum engineers, cross section, agreement, permeability Subjects: Reservoir Fluid Dynamics, Reservoir Simulation, Flow in porous media This content is only available via PDF. 1994.
