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......
Miscible Displacements of Reactive and Anisotropic Dispersive Flows in Porous Media
Transport in Porous Media - Tập 77 - Trang 489-506 - 2008
The viscous fingering instability of miscible reactive–dispersive flows in a homogeneous porous media is investigated through nonlinear numerical simulations. In particular, the role of velocity-dependent transverse and longitudinal dispersions as well as the type and rate of auto-catalytic chemical reactions is analyzed. It is found that for a third-order auto-catalytic reaction, the higher the r......
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......

Correction to: A Numerical Investigation of the Mean Free Path Distribution in the Knudsen Regime

In Eq. (11) there is a comma missing in the subscript.
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......
Validation of the Slow Compressional Wave in Porous Media: Comparison of Experiments and Numerical Simulations
Transport in Porous Media - Tập 36 - Trang 149-160 - 1999
We perform numerical simulation of ultrasonic experiments on poroelastic samples, in which Biot's slow compressional wave had been observed. The simulation is performed using OASES modeling code, which allows to compute elastic wave fields in layered poroelastic media. Modeled were the experiments of Plona (1980), Rasolofosaon (1988), and our own measurements. In all the three situations, a good a......
A Finite Element-based Heuristic Estimation of Local Preform Permeability for Resin Transfer Molding
Transport in Porous Media - Tập 76 - Trang 247-263 - 2008
Uniformity of fabrics significantly affects the resin flow behavior in the resin transfer molding (RTM) process. Due to fabric defects or improper fiber preform preparation/loading, non-uniformity in fabric structure frequently occurs in RTM processing and creates local permeability variations. Such variations often lead to unbalanced resin flow patterns and thus result in defects of finished comp......
