CO2 mass transfer and interfacial studies for application of carbonated water injection: Axisymmetric pendant drop analysis for simultaneous calculation of CO2 diffusion coefficient and interfacial tension
(PhD thesis UiS;439, Doctoral thesis, 2019-02)Worldwide, enhanced oil recovery (EOR) projects have been on a gradual rise since early 2000, especially EOR by CO2 injection. Globally, at present, EOR by CO2 injection contributes approximately 67.5% of projects (83 of ... -
Impact of Wettability on Rock Mechanics and Oil Recovery: A Comparative Study on Different Outcrop Chalks
(PhD thesis UiS;502, Doctoral thesis, 2020-04)Chalk reservoirs are highly fractured and are known for their remarkable storage capacity as a reservoir rock for the petroleum industry. Chalk is a sedimentary carbonate rock primarily made up of calcium carbonate (calcite, ... -
Interaction of silica nanoparticles with chalk and sandstone minerals: Adsorption, fluid/rock interactions in the absence and presence of hydrocarbons
(PhD thesis UiS;452, Doctoral thesis, 2019-04)Conventional oil production from petroleum reservoirs generally leaves more that 50% of the original oil in place unrecovered. This residual oil is the target of various enhanced oil recovery (EOR) techniques that involve ... -
Mathematical modeling of cancer cell migration - from in vitro to in vivo
(PhD thesis UiS;511, Doctoral thesis, 2020-05)Tumors has been the object of computational model studies for nearly five decades. The early models considered simple tumor growth based on nutrients, whereas models now can simulate from microscale gene expressions in ... -
Mathematical Modelling of the Drilling Process for Real-time Applications in Drilling Simulation, Interpretation and Assistance
(PhD thesis UiS;, no.;506, Doctoral thesis, 2019)For the last thirty years, mathematical modelling has been used to develop software solutions that support drilling engineering activities at the planning stage of drilling operations. But it is only for the last decade ... -
Numerical Modelling of Gas Production and CO2 Injection in Tight Shale Reservoirs for Enhanced Gas Recovery
(PhD thesis;560, Doctoral thesis, 2020-11)Natural gas production from shales has become exceedingly important in satisfying the ever-growing global energy demands. This unconventional hydrocarbon system is globally abundant, with large technically recoverable ... -
Particle Settling in shear thinning non-Newtonian drilling fluids : Effect of oscillatory motion
(PhD thesis UiS;537, Doctoral thesis, 2020-09)When drilling fluids circulate through the well and during the solids control operations, they are exposed to vibrations and oscillations of different frequencies and amplitudes. The secondary flow structures in oscillatory ...
