Predictive Modelling of Hydrate Formation and Dissociation

Natural gas hydrates are often considered as a hazard in hydrocarbon production and pipeline transport, but are also recognized as a potential energy resource. Naturally occurring hydrate deposits exist under suitable conditions of low temperature and high pressure, typically in shallow marine sediments and in and below the permafrost, and may...

Study of the effects of the dryout function parameters in heterogeneous reservoirs and experimental challenges of carbon dioxide foams in microfluidics

Gas injection processes suffer from poor volumetric sweep efficiency due to phenomena such as viscous fingering caused by density contrast between the injected gas and the displaced fluid, channeling due to heterogeneities in the reservoir and gravity override due to the inherent lower density of gas. One possible way to overcome these negative...

Engineering a horizontal layer of reduced permeability using Al-DOM precipitation

Leakage of contaminants to the subsurface is a potential threat to groundwater and is a major problem with storage tanks. When the contaminant reaches the groundwater, it can be subjected to subsurface flow due to which a contaminant plume may form and the contaminant can spread. In this research, it was investigated if a horizontal layer of...

The effect of surfactant type, velocity and permeability on CO2 foam under miscible conditions

Miscible gas injection has been widely used worldwide to improve oil recovery. However, problems such as viscous fingering and gravity override undermine its success on a large scale. Foaming of the injected gas mitigates these problems by reducing the mobility of the gas.<br/><br/>Past studies using an ionic surfactant to foam CO2 in the...
