Drilling and Well - Valve usage in changing environment
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Since the oil price experienced its drastic fall summer 2014, a leaner and more cost effective oil and gas production have been an important element for oil and gas companies. This is why this paper in cooperation with ... -
Experimental Study of Particle Dynamics in Circular Channel Flow
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)The study of liquid-particle interaction is the vital importance in many industries, especially for the petroleum well drilling and hole-cleaning operations. The data obtained from laboratory-scale experiments, simulations, ... -
Optimizing carbonate core restoration procedures - Effect of crude oil saturation and mild cleaning
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Wettability has a big impact on how much we can recover by water flooding a reservoir, and there is a commercial potential for improvement done through alteration of the wettability. Studies have been conducted and shown ... -
Synthesis, characterization, and activity of bimetallic Ni-Fe hydrotalcite-derived catalysts in dry reforming of methane
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)The extensive amount of carbon dioxide (CO2) emitted into atmosphere is arguably considered to be the main reason for global climate change due to the greenhouse effect. For decades, considerable efforts have been devoted ... -
Stochastic thermodynamic production model for shale gas reservoirs
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Most operating companies use Decline Curve Analysis (DCA) for their production forecast on Shale Gas assets (Mongalvy, Chaput and Agarwal, 2011). DCA method is based in empirical analysis and the theoretical background ... -
Adsorption of silica nanoparticles in chalk and sandstone and it effect of fluid/rock interactions.
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)This study addresses the adsorption of Silica nanoparticles (NPs) and its effect on fluid/rock interactions in chalk and sandstone reservoirs. The first part of this thesis addresses the kinetic adsorption behaviour of ... -
Digital Image Analysis for Petrophysical Evaluation
