(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-07-13)An oil and gas discovery goes through a multiple-stage process to increase the understanding of the asset in hand. By increasing the understanding of the field, production plan gains extra credibility and the uncertainty ... -
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 ... -
Production of Smart Water by Acid Flooding in Chalk: Temperature Limitation at Slightly Water-Wet Conditions
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)Seawater has proven to be an excellent injection fluid in chalk due to its ability to alter the wettability towards more water-wet conditions at high temperatures. This chemically induced wettability alteration improves ... -
Provenance Evaluation of Lower Cretaceous in the Stappen High Area and Implications for Reservoir Development
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-07-28)Southeast directed fluvio-deltaic systems transported across Svalbard during Early Cretaceous are age correlated to southeast progradation deposits in the in Fingerdjupet Subbasin. Both local (few km) and distal (>300 km) ... -
Provenance on the Lysing-Lange megasequences on the Dønna Terrace: focus on stratigraphic variability and lateral sandbody connectivity
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-29)The Cenomanian to Coniacian-Turonian Lange-Lysing megasequences are located on the Dønna Terrace in the Norwegian Sea. Provenance study using traditional provenance methods such as petrography, whole-rock geochemistry, and ... -
Quantitative seismic interpretation using converted PS waves: A case study from the Oseberg South Field, North Sea
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-06)The converted wave (PS) seismic in combination with the compressional wave (PP) seismic may help in better description and understanding of subsurface stratigraphic and structural features. Since compressional and shear ... -
Reactive Flow Simulation
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Sea water-injection in carbonate formations leads to reactive processes that are linked to affecting oil recovery via wettability alteration and chemical compaction. The concentrations of divalent ions, such as Ca2+, Mg2+, ... -
Reservoir Characterization of the Snorre field: A pseudo wells based inversion approach
(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 ... -
Reservoir Modeling and Uncertainty Estimation: A Comparison Between Stochastic and Deterministic Inversion.
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-29)This study compares the uncertainty estimation based on both deterministic and stochastic inversion with the Gauss Simulation technique applied to modelling the distribution of limestone facies in a sand-shale reservoir. ... -
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. ... -
Salt Controlled Fluvial Systems in the Norwegian Danish Basin, Central North Sea; The Impact on Triassic Petroleum Prospectivity
