Pore Scale Network Modeling approach PDF

Abbas Khaksar Manshad

The architecture and geometry of the void space of a porous medium and its complementary grain matrix determine several macroscopic properties of the rock such as porosity, relative permeability and capillary pressure. Therefore, it is important to study the microscopic structure of the reservoir pores and understand the physical fluid displacements through them. One approach to this problem is pore-scale modeling that requires a detailed understanding of the physical processes occurring on the pore scale and a complete description of the morphology of the pore space. The pore scale network is a representation of the void space of the reservoir rock. Wide voids of the reservoir rocks are represented by the pore bodies which are interconnected by narrow spaces called pore throats. The key results of the network model are the ability to predict the trend in relative permeability, capillary curves, fractional flows and residual saturations with capillary number and viscosity ratio and to reproduce the displacement patterns.

Pore Network Modeling - COIFPM Pore network modeling attempts to describe the multiphase flow properties inside a digital porous media with geologically realistic networks. Multiphase flow in porous media occurs in many natural and artificial processes, such as subsurface flow of hydrocarbons and brine, geologic storage of CO2, reactive transport through catalysts, and non-aqueous phase liquids (NAPL) migration in soil.

A Coupled Pore-Scale Modelling Approach to … Abstract After a critical review of available pore-scale analytical and numerical approaches to estimate permeability of porous media, this paper presents a practical framework to examine and quantify the impact of variation of confining stress during the production lifecycle of a reservoir on the pore space deformation and absolute permeability of rocks formed by spherical grains.
