Naturally fractured reservoirs (NFRs) gain much attention worldwide because they are often encountered in aquifer remediation, CO2 sequestration, and hydrocarbon extraction. In hydrocarbon extraction, however, oil recovery by gas injection in NFRs is usually low, because of poor sweep efficiency. During gas injection, the displacement front is...

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...

Fatemi, S.A. (author)
This dissertation focuses on polymer flooding, as an example of an EOR process. Chemical floods such as polymer floods are EOR techniques intended to increase sweep and/or displacement efficiency. Even though the compatibility and the efficiency of the injected chemicals are thoroughly tested and validated in the laboratory, uncertainty still...

Foam increases sweep efficiency during gas injection in enhanced oil recovery (EOR)<br/>processes by reducing gas mobility. In fact, foam is the only EOR technology that is<br/>able to fight against both gravity segregation and geological heterogeneity. Surfactant Alternating Gas, or SAG, is the preferred method to place foam into the reservoir...

Foam flooding can be applied in soil-remediation techniques or for improving oil recovery processes in petroleum reservoirs. There are models which aim to predict the behaviour of foam in presence of oil in bulk and in porous media, however these models are not very reliable. In this work we investigate different ways in which a specific crude...

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...

A large number of oil and gas reservoirs across the world are naturally <br/>fractured, f r om which a significant amount of hydrocarbons are produced. <br/>Naturally fractured reservoirs, like all reservoirs, are exploited in t w o stages: <br/>primary recovery and secondary recovery (sometimes followed by tertiary <br/>recovery, i.e. enhanced...

To reduce CO2 emissions into the atmosphere, different scenarios are proposed to capture and store carbon dioxide (CO2) in geological formations (CCS). Storage strategies include CO2 injection into deep saline aquifers, depleted gas and oil reservoirs, and unmineable coal seams. To identify a secure and proper strategy for CO2 injection, the...

Ashoori, E. (author)
Foam increases sweep in miscible- and immiscible-gas enhanced oil recovery by decreasing the mobility of gas enormously. This thesis is concerned with the simulations and analytical solutions for foam flow for the purpose of modeling foam EOR in a reservoir. For the ultimate goal of upscaling our modeling results to foam EOR in reservoir, it is...

Namdar Zanganeh, M. (author)
Chemical enhanced oil recovery (EOR) is relatively expensive due to the high cost of the injected chemicals such as surfactants. Excessive use of these chemicals leads to processes that are not economically feasible. Therefore, optimizing the volume of these injected chemicals is of extreme importance. We intend to maximize the long-term...

Salimi, H. (author)
This thesis is concerned with upscaled models for waterflooded naturally fractured reservoirs (NFRs). Naturally fractured petroleum reservoirs provide over 20% of the world’s oil reserves and production. From the fluid-flow point of view, a fractured reservoir is defined as a reservoir in which a number of naturally occurring fractures have a...
