Foam injection is a promising means of reducing the relative mobility of gas, and hence improving the sweep efficiency of gas, in CO<sub>2</sub> and H<sub>2</sub> storage, soil-contaminant removal in aquifer remediation, enhanced oil recovery, and matrix-acid well stimulation. Theory (Rossen and Gauglitz, 1990; Ashoori et al., 2012) and...

Creating a gas-liquid foam means dispersing gas as individual bubbles in an aqueous solution, in which each gas bubble is separated by liquid films or lamella. The most common form of liquid foam (as opposed to solid foams, like polymer sponges) seen in day-to-day life is bulk foam. This refers to a foam that rests in a large container (or flows...

Steady multiphase flow in two-dimensional (2D) porous media has not been established without the continuous fluctuation in pore occupancy. Cox (2019) proves the ability of liquid to bridge a gas-filled pore throat that is narrow and deeply etched, allowing liquid and gas to flow simultaneously. In this investigation, a pore network study was...

Foam greatly reduces gas mobility for gas enhanced-oil-recovery (EOR) projects. It substantially increases both the effective viscosity of gas and gas trapping. Numerous studies have been conducted to understand foam rheology in rock matrix both theoretically and experimentally. The knowledge of foam flow in fractured porous media is...

Gas is used in petroleum reservoirs to displace oil for enhanced oil recovery. The microscopic displacement efficiency of gas is very good, but at the reservoir scale the process suffers from poor sweep efficiency, especially in naturally fractured reservoirs. Foam can improve the sweep. There have been considerable scientific contributions...

Foam is useful as an enhanced oil recovery method to reduce gas mobility and prevent gravity override to improve sweep efficiency. Foam is generated in porous media when exceeding a critical velocity and pressure gradient, that usually occur near to an injection well. There is the uncertainty of foam generation in the low-pressure gradient and...

Foam is a promising solution for improving the poor sweep efficiency of gas injection for enhanced oil recovery (EOR), in that foam lowers gas mobility significantly by trapping gas bubbles. Most of oils destabilize foam, the effect of which dominates foam strength when foam is in contact with oil and is key to success of foam EOR, but not yet...

Naturally fractured reservoirs (NFRs) are found in many countries around the globe, in almost every lithology. These reservoirs can be carbonates, sandstones, or shale, in the case of unconventional or basement reservoirs. NFRs have been explored and exploited globally for groundwater, geothermal energy, hydrocarbon production, coalbedmethane...
