(Bachelor thesis, 2021)Thesis about carbon dioxide storage in saline aquifers and other sedimentary basins -
Carbonated water injection in chalk for enhanced oil recovery at high temperature
(Master thesis, 2022)The increased demand of hydrocarbons in combination with the climate change represent a current challenge for a petroleum industry that aims to increase the production and reduce its emissions. Reaching the Paris agreements ... -
Casestudie av væske/vann-varmepumpe
(Bachelor thesis, 2021)Oppgaven tar utgangspunkt i en enebolig lokalisert i Stavanger, som i forbindelse med rehabilitering, installerte en væske/vann-varmepumpe. Det spesielle med dette anlegget er at varmeenergien hentes fra en kuldebærer, ... -
Catalytic conversion of CO2 to methanol over Cu/Zn/Al catalysts promoted with cerium and lanthanum
(Master thesis, 2022)Carbon dioxide is one of the most prominent greenhouse gases, and the rise in its emissions is causing an increase in the world’s temperature, which can have catastrophic effects if it is not controlled. Governments and ... -

Catalytic conversion of CO2 to methanol via CO2 hydrogenation : An investigation of metal oxide promoted catalysts
(PhD thesis UiS;574, Doctoral thesis, 2021-02)CO2 hydrogenation to methanol is a promising process for converting renewable energy into valuable fuels and chemicals, which can combat the emissions of greenhouse gases associated with the use of fossil resources. ... -
Catalytic hydrogenation of CO2 to methanol over In-promoted Cu/ZnO/Al2O3 derived from hydrotalcite-like precursors
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)Carbon dioxide emissions present a threat on a global level, driving governments and the scientific society to search for sustainable solutions to ease the effects of climate change. Carbon utilization offers a potentially ... -
Cement Placement: An Overview of Fluid Displacement Techniques and Modelling
(Peer reviewed; Journal article, 2021-01)During drilling operations, effective displacement of fluids can provide high-quality cementing jobs, ensuring zonal isolation and strong bonding of cement with casing and formation. Poor cement placements due to incomplete ... -
Cement properties characterization from a section retrieved from an oil production well after 33 years of downhole exposure
(Peer reviewed; Journal article, 2021)A unique data set has been constructed based on the study of class G cement recovered from an oil well on the Norwegian continental shelf. The cement was placed between two casing sections and submitted to downhole conditions ... -
Cfd analysis of low frequency oscillations in Newtonian and non-Newtonian fluids in a vertical pipe
(Peer reviewed; Journal article, 2019)The effect of vertically imposed, low frequency oscillations on the rheology of shear-thinning non- Newtonian fluids are studied numerically by computational fluid dynamics (CFD). Both Newtonian (water) and inelastic ... -
Challenges associated with mercury occurrence on the Norwegian Continental Shelf
(Master thesis, 2023)The thesis includes a review of the heavy metal mercury, with focus on its origin, effect on the environment, and its role in the petroleum industry. Mercury emissions from the petroleum industry in Norway is looked into ... -
Characteristic forced and spontaneous imbibition behavior in strongly water-wet sandstones based on experiments and simulation
(Peer reviewed; Journal article, 2022-05)Forced and spontaneous imbibition of water is performed to displace oil from strongly water-wet Gray Berea (~130 mD) and Bentheimer (~1900 mD) sandstone core plugs. Two nonpolar oils (n-heptane and Marcol-82) were used as ... -
Characterization of Annular Cement Permeability of a Logged Well Section Using Pressure-Pulse Decay Measurements
(Peer reviewed; Journal article, 2022)The cement behind casings is an important barrier element in wells that should provide zonal isolation along the well. The hardened cement does not always isolate permeable formations, either due to placement issues or ... -
Characterization of annulus well cement quality to estimate the leakage potential in cement well barriers
(PhD Theses;676, Doctoral thesis, 2022-11)Cement is nowadays the most used material that is placed inside of wells as a barrier element to ensure zonal isolation and avoid migration of fluids between the reservoir and surface. Sometimes the well integrity can be ... -
Characterization of the mud displacement in an enlarged wellbore: An integrated rock-fluid model
(Peer reviewed; Journal article, 2022)Cement-mud displacement plays a crucial role in the sealability of cement sheaths. Irregular geometric features of a wellbore due to washout can have a negative impact on mud and cement mobilization. An unstable interface ... -
Classification of Hydraulic Flow Units in the Whicher Range Field
(Bachelor thesis, 2021)Determination of reservoir rock type is one of the most important tasks for simulation, modelling and prediction of the hydrocarbon reservoir behavior. Hence, using methods that predict rock types as accurately as possible, ... -
