Dynamics of multiphase dispersed systems in rotating annulus
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)An investigation of multiphase dispersed system dynamics in rotating annulus is described. The investigation was based on measuring rheological constant (viscosity) of two-phase flowing system. The flow was obtained between ... -
Effect of barium and strontium on low salinity waterflooding
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-27)Much work has been done on the subject of low salinity waterflooding (LSWF) as a potential enhanced oil recovery method. It has been shown many times that reducing the salinity of the injected brine could have a positive ... -
Effect of IFT on gravity segregation in mixed wet reservoir
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The effects of water-oil interfacial tension (IFT) on gravity segregation and its implication on oil recovery have been investigated by numerical simulations and steady state upscaling. Eclipse surfactant model was used ... -
Emulsions For Enhanced Oil Recovery EOR
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)______Oil recovery projects have become a valuable source in oil industry in the recent years due to market challenges and economic stability. This is a typical practice that have been applied in oil and gas reservoirs to ... -
Evaluating Flowing Conditions of Faults and Fractures from Well Testing and Interpretation: A Study Based on Reservoir Simulation
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)The scope of the thesis was inspired by the studies of CO2 storage in saline aquifers containing faults conducted at IRIS within the ENOS project1. In storage site evaluations, assessing and preventing leakage from the ... -
Evaluating the potential of low-salinity water flooding to enhance the oil recovery in limestone reservoir
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)In this project, the potential of low salinity brine to enhance the oil recovery has been studied. Four flooding tests were conducted both on limestone cores containing anhydrite and chalk core containing no sulfate. -
Evaluation of low salinity injection EOR potential in Johan Sverdrup Field
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017)Low salinity waterflooding is an EOR method that doesn’t get mentioned as much as other EOR methods in the current oil industry, but its recognition has been raised in the last few years and BP is also using their own low ... -
Evaluation of silicate and polymer systems for disproportionate permeability reduction in oil reservoirs
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)The main objective of this work is to screen and evaluate various commercially existing polymers and silicate systems mixed with crosslinkers and/or activators for their gel-forming capabilities for the water management ... -
Evaluation of using Smart Water to enhance oil recovery from Norwegian Continental Shelf sandstone reservoirs.
(Master thesis, 2016-06-09)Recently, the scale of studies on smart water – one of EOR method - has increased. From decades, water flooding is one of the most used methods to increase oil recovery. However, more effective in sandstone reservoirs is ... -
Evaluation of WAG injection at Ekofisk
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)In the North Sea many fields are water flooded. Subsequent to water flooding large amounts of water flood residual oil will be left in reservoirs. The challenge is how to improve the oil recovery. On the Ekofisk field such ... -
Evolution of porosity and permeability in chalk as an effect of variations in non-carbonate minerals and testing temperature
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)Pressure decline during oil recovery from chalk reservoirs exhibit increase in effective stress and this in turn leads to reservoir compaction causing seabed subsidence. Although, there is positive impact of compaction on ... -
Examination of Dynamic Stress and Conductivity in the Eldfisk Chalk Field
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-05-26)This thesis work has been conducted in cooperation with ConocoPhillips Norway and looks at the stress development in the Eldfisk chalk reservoir. High injection pressures due to the relatively low permeabilities of chalk ... -
Experimental study of low salinity EOR effects from the Varg field
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The extra oil recovery obtained when flooding a sandstone reservoir with low saline water is called low salinity (LowSal) effect. The term salinity refers to amount (and type) of salt that makes up the ionic composition ... -
Field-scale simulation modeling of disproportional permeability reduction impact on oil recovery
