Steam injection into water-saturated porous rock

Wettability of Steam-water-rock Systems

A method has been developed to infer the wettability of steam-water-rock systems based on the relationship between permeability and capillary pressure by Purcell. The Purcell model was extended to two-phase flow to verify whether the wettability is a function of water saturation. The results calculated using the experimental data showed that the wettability index in drainage was greater than th...

Coupling heat conduction and water–steam flow in a saturated porous medium

This paper is devoted to the simulation of water forced evaporation in a porous saturated medium in a 3Daxisymmetric domain by resolution of partial differential algebraic equations (PDAE) that are encountered in different engineering applications. The goal of this paper is an attempt to present effective realizations, in order to determine the minimal duration of burning for prehistoric occupa...

Effective Conductivity Modeling of a Fluid Saturated Porous Rock

The microstructure of a porous medium and physical characteristics of the solid and the fluids that occupy the pore space determine the macroscopic transport properties of the medium. The computation of macroscopic properties from the rock microtomography is becoming an increasingly studied topic. The transport properties are especially difficult to determine at the microscopic scale. In this p...

Ground Water Issue: Steam Injection for Soil and Aquifer Remediation

Innovative technologies for subsurface remediation, including in situ techniques based on heating the subsurface to enhance the recovery of organic contaminants, are increasingly being evaluated for use at specific sites as the limitations to the conventionally-used techniques are recognized. The purpose of this Issue Paper is to provide to those involved in assessing remediation technologies f...
