摘要： Computer-implemented systems and methods are provided for an upscaling approach based on dynamic simulation of a given model. A system and method can be configured such that the accuracy of the upscaled model is continuously monitored via indirect error measures. If the indirect error measures are bigger than a specified tolerance, the upscaled model is dynamically updated with approximate fine-scale information that is reconstructed by a multi-scale finite volume method. Upscaling of multi-phase flow can include flow information in the underlying fine-scale. Adaptive prolongation and restriction operators are applied for flow and transport equations in constructing an approximate fine-scale solution.

摘要： An apparatus and method are provided for solving a non-linear S-shaped function F = f(S) which is representative of a property S in a physical system, such saturation in a reservoir simulation. A Newton iteration (T) is performed on the function f(S) at S V to determine a next iterative value S V+1 . It is then determined whether S V+1 is located on the opposite side of the inflection point S C fromS V . If S V+1 is located on the opposite side of the inflection point fromS V , then S V+1 is set to S 1 , a modified new estimate. The modified new estimate, S 1 , is preferably set to either the inflection point, S C , or to an average value between S V and S V+1 , i.e. , S 1 = 0.5( S V + S V+1 ). The above steps are repeated until S V+1 is within the predetermined convergence criteria. Also, solution algorithms are described for two-phase and three-phase flow with gravity and capillary pressure.

摘要： A Multiscale Finite Volume (MSFV) method is provided to efficiently solve large heterogeneous problems; it is usually employed for pressure equations and delivers conservative flux fields to be used in transport problems. It relies on the hypothesis that the fine-scale problem can be described by a set of local solutions coupled by a conservative coarse-scale problem. In numerically challenging cases, a more accurate localization approximation is used to obtain a good approximation of the fine-scale solution. According to an embodiment, a method is provided to iteratively improve the boundary conditions of the local problems, and is responsive to the data structure of the underlying MSFV method and employs a Krylov-subspace projection method to obtain an unconditionally stable scheme and accelerate convergence. In one embodiment the MSFV operator is used. Alternately, the MSFV operator is combined with an operator derived from the problem solved to construct the conservative flux field.

摘要： The present invention includes a method, system and apparatus for simulating fluid flow in a fractured subterranean reservoir. A three-dimensional hybrid reservoir model representative of a fractured subterranean reservoir is created. The model includes porous matrix blocks and a network of long fractures overlying the matrix blocks. The networks of long fractures include two-dimensional fracture blocks. Matrix and fracture flow equations for fluid flow in the matrix and fracture blocks are obtained. The effective fluid flow transmissibilities between the matrix blocks and the fracture blocks are determined. The matrix and fracture flow equations are coupled via the effective fluid flow transmissibilities. The matrix and fracture flow equations are then solved simultaneously for flow responses. Two-dimensional fracture blocks are used which ideally overly and are fluidly connect to underlying matrix blocks. The long fractures may be in direct in fluid communication with one or more intersecting wells. Where long fractures intersect with one another, the intersection of the long fractures may be modeled as a point source to enhance numerical stability during simulation. The hybrid reservoir model may utilize networks of fractures in conjunction with an underlying grid of matrix blocks wherein fracture characteristics such as (1) orientation; (2) fracture aperture; (3) fracture length; and (4) fracture height are more realistically modeled than in previously known reservoir models.
