Fluid flow through porous media, and the thermal, electrical, acoustic properties of these materials, is largely controlled by geometry topology (GT) pore system, which can be considered as a network. Network extraction techniques have been applied in many research fields, including shape representation, pattern recognition, artificial intelligence. However, set algorithms presented here significantly improves efficiency common thinning introducing sufficiency condition based on idea simple...
[1] Developing a better understanding of single-/multiphase flow through reservoir rocks largely relies on characterizing and modeling the pore system. For simple homogeneous rock materials, complete description real structure can be obtained from network extracted image at single resolution, then an accurate prediction fluid properties achieved by using model. However, for complex (e.g., carbonates, heterogeneous sandstones, deformed rocks), comprehensive may involve several decades length...
ABSTRACT Outcrop studies reveal a common occurrence of tabular zones significantly‐increased fracture intensity affecting otherwise well‐lithified rocks. These zones, called corridors, can have profound effect on multi‐phase fluid flow in the subsurface. Using standard geo‐modelling tools, it is possible to generate 3D realizations reservoirs that contain distributions such corridors are consistent with observations, including vertical frequency pseudo‐wells inserted into model at random...
Pore networks can be extracted from 3D rock images to accurately predict multi-phase flow properties of rocks by network simulation. However, the predicted may sensitive pore if it is small, even though its underlying characteristics are representative. Therefore, a challenge investigate effects on microscopic features individually and collectively based small samples. In this article, new approach introduced generate an initial stochastic arbitrary size that has same as parent network....
Modern scanning electron microscopes often include software that allows for the possibility of obtaining large format high-resolution image montages over areas several square centimeters. Such are typically automatically acquired and stitched, comprising many thousand individual tiled images. Images, collected a regular grid pattern, rich source information on factors such as variability in porosity distribution mineral phases, but can be hard to visually interpret. Additional quantitative...
The overpressure history of a sandstone can be estimated using numerical model if the burial curve and geological setting are known. From resulting effective stress, maximum potential porosity (MPP) calculated. MPP is rock could theoretically hold open at modeled depth pore pressure. Measured porosities should or below MPP. We have determined for Fulmar Formation sandstones (Upper Jurassic) Central Graben, North Sea, compared predictions to measured core data. conclude that majority...
We use a two-scale continuum model to simulate reactive flow and wormhole formation in carbonate rocks under 3-D radial conditions. More specifically, we present new structure-property relationship based on the fractal geometry theory, describe evolution of local permeability, pore radius, specific area with porosity variation. In numerical calculation, improve convergence rate, heterogeneous medium question is extended by adding thin layer homogeneous porous its inlet. compare simulation...
Abstract High‐speed neutron tomographies (1‐min acquisition) have been acquired during water invasion into air‐filled samples of both intact and deformed (ex situ) Vosges sandstone. Three‐dimensional volume images processed to detect track the evolution waterfront calculate full‐field measurement its speed advance. The flow process correlates well with known rock properties is especially sensitive distribution altered associated observed localized deformation, which independently...
Abstract Understanding and predicting fracture propagation subsequent fluid flow characteristics is critical to geoenergy technologies that engineer and/or utilize favorable geological conditions store or extract fluids from the subsurface. Fracture permeability decreases nonlinearly with increasing normal stress, but relationship between shear displacement less well understood.

Abstract Naturally fractured reservoirs, within which porosity, permeability pathways and/or impermeable barriers formed by the fracture network interact with those of host rock matrix to influence fluid flow and storage, can occur in sedimentary, igneous metamorphic rocks. These reservoirs constitute a substantial percentage remaining hydrocarbon resources; they create exploration targets otherwise rocks, including under-explored crystalline basement, be used as geological stores for...
Abstract The analysis of the 3D microstructure porous materials is importance in multiple disciplines, such as reservoir engineering and environmental science. We have developed a suite methods to characterize geometry topology pore systems from images samples, allowing us extract network representations for use flow models that predict single‐/multi‐phase fluid properties. Using these methods, we investigated geometric topological factors major impact on prediction. parameters describe...
The lattice Boltzmann (LB) method has proven to be a promising for simulating fluid dynamics in porous media. When flow pores is the only concern, standard LB implementation, which stores one or two sets of particle distribution functions (PDFs) both pore and solid cells, wastes large amount memory, especially low-porosity This paper proposes implementation scheme that single set PDFs cells therefore makes it possible simulate through larger more-realistic models. A unique feature this...
