RISFactors Affecting Alkaline Sodium Silicate Gelation for In-Depth Reservoir Profile Modification
Alkaline sodium silicate (Na-silicate) is environment-friendly and possesses water-like viscosity during the injection stage for in-depth reservoir treatment to enhance sweep efficiency. Gel setting time (tg) and gel ...
Pore-scale modeling of non-isothermal two phase flow in 2D porous media: Influences of viscosity, capillarity, wettability and heterogeneity
This paper addresses simulation of non-isothermal water-oil displacements in porous media at porescale.
The simulation approach was done by coupling Cahn–Hilliard phase field and heat equations using
COMSOL ...
Evaluation of level set and phase field methods in modeling two phase flow with viscosity contrast through dual-permeability porous medium
This work assesses conservative level set method (LSM) and Cahn–Hilliard phase field method (PFM) in modeling 2D two-phase flow through porous media, based on their ability to capture different phenomena associated with ...
Sodium Silicate Behavior in Porous Media Applied for In-Depth Profile Modifications
This paper addresses alkaline sodium silicate (Na-silicate) behavior in porous media. One of the advantages of the Na-silicate system is its water-like injectivity during the placement stage. Mixing Na-silicate with saline ...
