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 ... -
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 ... -
Reservoir Simulation of Chemical Inflow Tracers in Horizontal Wells
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)Conventional production logging tools can be challenging to deploy and interpret in long horizontal wells. Inflow tracer technology can address these challenges, by allowing continuous monitoring of the horizontal section. ... -

(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)Complex reservoirs make hydrocarbon exploration challenging, and therefore improvement of methods for discovering and producing hydrocarbons is desired. Consequently, various seismic inversion algorithms have been developed ... -
Production of Smart Water by Acid Flooding in Chalk Cores: Oil Recovery Effects at Intermediate Temperature
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)Considering that most carbonates are of low water wetness, it is of great interest to inject a brine that can alter the wettability to enhance oil production. Smart Water injection has therefore become the most meaningful ... -
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 ... -
Seismic imaging with primaries and multiples
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Multiples are usually considered as noise in seismic images due to their interferences with primary reflections. In recent years, new imaging methods have been developed which consider multiples as secondary sources to ... -
3D seismic analysis of the Basement to Early Cretaceous in the Selje High, Slørebotn Sub-basin and Måløy Slope, southern Norwegian Sea.
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Several coarse-grained sedimentary rocks have been reported in the Upper Jurassic and the Cretaceous succession in the southern Norwegian Sea and the northern North Sea. The Jurassic interval has been interpreted as syn-rift ... -
Smart Water EOR potential in Brazilian oilfields
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)The fact that the petroleum industry still invest a lot of money on different oil recovery techniques indicates that there is an increasing demand for oil that needs to be met. Water flooding is a common secondary oil ... -
Effect of Wettability on Waterflooding and Relative Rermeability at Medium Water-Wet Conditions.
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)This project contributes with experimental measurement that could increase our understanding on how relative permeability is affected by wettability during an oil recovery process. Wettability has significant attention ... -
MICP-Based Rock Typing of Complex, Multi-Modal Formations in Edvard Grieg Field
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Rock/pore typing is a process of classifying reservoir rocks into units with similar petrophysical properties. When properly classified, each unit possesses a unique porosity-permeability relationship. This leads to improved ... -
Sediment growth around salt diapirs: Analysis and interpretation using full-azimuth seismic data from the Central Nordkapp Basin, SW Barents Sea
