The Effects of Oil on CO2 Foam Flooding under Miscible Conditions

Miscible gas injection, as an Enhanced Oil Recovery (EOR) method, can improve the recovery factor by swelling the residual oil and phasing out the interfacial tension. However, the sweep efficiency of miscible gas injection is not satisfactory because of conformance problems, such as viscous fingering, channelling and gravity override. Foam can...

Influence of Transient Effects on Fitting Parameters to SAG Foam Core-Foods

Foam is a promising means of increasing sweep efficiency in enhanced oil recovery processes where gas is injected into a reservoir. However, the effectiveness of foam is hard to predict due to its complex behavior. Therefore accurate modeling is important to effectively predict field performance. This requires correct foam parameters in...

Reservoir Simulation of Foam Flow using a Kepler GPU

In recent years, along with the higher GPU’s computational speed and memory bandwidth compared to those of CPUs, GPU-accelerated reservoir simulation has been studied quite extensively. The results so far have shown that Fermi generation GPUs could accelerate IMPES (implicit pressure explicit saturation) reservoir simulation considerably. Along...

Effect of Diffusion on Foam Bubble Size Distribution and Gas Mobility: An Idealized 2D Model

In this thesis the effect of gas diffusion between bubbles on the bubble-size distribution and capillary resistance to foam flow in a bubble train is investigated using an idealized 2D pore model. First the shape of the model pore is discussed and how a lamella moves through it. Then the physical forces (lamella curvatures and pressure...
