In-Situ Capillary Trapping of CO2 by Co-Injection
Transport in Porous Media - Tập 90 - Trang 575-587 - 2011
Co-injection of water with CO2 is an effective scheme to control initial gas saturation in porous media. A fractional flow rate of water of approximately 5–10% is sufficient to reduce initial gas saturations. After water injection following the co-injection, most of the gas injected in the porous media is trapped by capillarity with a low fractional volume of migrating gas. In this study, we first......
Transient Pressure Behavior of Reservoirs with Discrete Conductive Faults and Fractures
Transport in Porous Media - Tập 95 - Trang 239-268 - 2012
Fractures and faults are common features of many well-known reservoirs. They create traps, serve as conduits to oil and gas migration, and can behave as barriers or baffles to fluid flow. Naturally fractured reservoirs consist of fractures in igneous, metamorphic, sedimentary rocks (matrix), and formations. In most sedimentary formations both fractures and matrix contribute to flow and storage, bu......

A Parametric Model for Predicting Relative Permeability-Saturation-Capillary Pressure Relationships of Oil–Water Systems in Porous Media with Mixed Wettability
Transport in Porous Media - Tập 31 - Trang 109-131 - 1998
A parametric two-phase, oil–water relative permeability/capillary pressure model for petroleum engineering and environmental applications is developed for porous media in which the smaller pores are strongly water-wet and the larger pores tend to be intermediate- or oil-wet. A saturation index, which can vary from 0 to 1, is used to distinguish those pores that are strongly water-wet from those th......
Numerical Simulation of Free Surface Fluid Flows Through Porous Media by Using the Explicit MPS Method
Transport in Porous Media - Tập 127 Số 1 - Trang 7-33 - 2019
An extension of the explicit moving particle semi-implicit (MPS) method is proposed for simulating free surface flow through a porous structure object. The model formulation is based on the local volume averaging equations, and the porous drag is given by a general closure function. It can compute the macroscopic behaviors of incompressible flows in porous media. Specifically, the present study ad......
Underground Storage of Hydrogen: In Situ Self-Organisation and Methane Generation
Transport in Porous Media - - 2010
In situ observations have shown that underground storage of hydrogen behaves like a natural chemical reactor and generates methane. The mechanism of this generation is the metabolic activity of methanogenic bacteria which consume hydrogen and carbon dioxide and transform them into methane and water. The coupled mathematical model of the reactive transport and population dynamics in a storage is su......
A Compressible Fluid Flow Model Coupling Channel and Porous Media Flows and Its Application to Fuel Cell Materials
Transport in Porous Media - Tập 134 - Trang 351-386 - 2020
A multi-dimensional, compressible fluid flow solver, valid in both channel and porous media, is derived by volume-averaging the Navier–Stokes equations. By selecting an appropriate average density/velocity pair, a continuous, stable solution is obtained for both pressure and velocity. The proposed model is validated by studying the pressure drop of two commonly used experimental setups to measure ......
