The Impact of Permeability on Density-Driven Convection During CO2 Storage in Underground Reservoirs
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)Within the context of global warming, CO2 storage in geological reservoirs is seen as one of many strategies to reduce greenhouse gas emissions over the next few decades. In CO2 storage, the water density increases upon ... -
Effect of Wettability on Waterflooding and Relative Permeability at Slightly Water-Wet Conditions
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)The wettability of a porous system is of high importance when waterflood behavior and relative permeability are investigated, because both will be strongly affected. Adsorption of polar organic components (POC) are responsible ... -
Analytical solutions for forced and spontaneous imbibition accounting for viscous coupling
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)Theoretical and experimental work has shown that fluid mobilities can depend on flow configuration, and are typically lower when fluids flow in opposite directions as compared to when they flow in the same direction. Such ... -
Hybridization of gradient-based and gradient-free optimization techniques for simultaneous optimization of number of wells, their location and drilling time in a 2-dimensional reservoir
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)Optimization has always been a challenging scope in any field of science, and reservoir management is no exception. By the advent of computational power, the use of mathematical algorithms in conjunction with reservoir ... -
