Embodiment Construction

[0033] refer to figure 1 , the system 10 is used to model a multiscale porous material with underresolved region(s) of the multiscale porous material. Simulations can be used for various purposes, such as for simulating "wettability recovery" or "aging" processes representative of subsurface reservoir conditions, ie "numerical aging". Other simulations can include the effect of vapor flow on PPE, etc.

[0034] The focus of this discussion will be the simulation of multiscale porous materials with underresolved region(s). Typically, the system 10 in this implementation is based on a client-server or cloud-based architecture and includes a (standalone or cloud-based) server system 12 and a client system 14 implemented as a massively parallel computing system 12 . Server system 12 includes memory 18 , bus system 11 , interface 20 (eg, user interface / network interface / display or monitor interface, etc.) and processing device 24 .

[0035] For an example of a change in wettabili...

Abstract

The invention relates to a computer simulation of multiphase multicomponent fluid flow including physical properties of an underresolved porous structure. Computer-implemented techniques for performing fluid simulation of porous media are disclosed. The techniques involve retrieving a representation of a three-dimensional porous medium, the representation comprising a void space corresponding to the porous medium, and the representation comprising at least a portion of an underparsed void structure in the porous medium, defining a representative flow model comprising the representation of the underparsed void structure, and constructing, by the computer system, a fluid force curve corresponding to the fluid force in the pore structure that is under-analyzed in the representation.

Description

Background technique [0001] The flow of multicomponent fluids through porous regions is an important property of hydrocarbon reservoir rocks and is a vital input to the oil and gas industry and beyond. [0002] Numerical simulation of multicomponent fluid flow in porous regions with complex solid structures is of great importance in many industrial applications such as enhanced oil recovery (EOR) and personal protective equipment (PPE). To obtain accurate simulation results, it is important to capture relevant data from all scales of the porous structure. [0003] For many porous materials, the scale range typically spans many orders of magnitude in size. Furthermore, scale ranges are often distributed heterogeneously in space. Full-scale analytical simulations of such porous structures are computationally prohibitive in terms of data size, computational time, and computational resources. Therefore, such simulations are generally limited to samples whose size is a significa...
