Study of the dynamic behaviour in a multiphase flow system when bubbles of CO2 or Air passes through the interface of two immiscible liquids.
(Master thesis, 2022)The behavior of bubbles at the interface between oil/water is studied. The test are done with Silicon Oil 10 cS as the overlaying liquid and aqueous solutions underneath. Polyanionic Cellulose (PAC) were implemented and ... -
Assessment of offshore thermochemical cuttings cleaner as a potential viable technology towards drilling and wells operations decarbonization.
(Master thesis, 2022)The energy industry- particularly the oil and gas- is facing unprecedented times to supply global energy resources to drive economic progression and reduce greenhouse gas emissions to limit global warming. As alternative ... -
Application of non-linear dynamics (SINDy) method of drill string model by machine learning.
(Master thesis, 2022)Numerous data floods research in various fields. Quickly grasping the laws of data and finding out equations are of great significance to the study of system characteristics and control systems. The goal of this thesis is ... -
Offshore Electrification - An overview of technologies, risks and costs associated to the Norwegian Continental Shelf
(Master thesis, 2022)The concentration of greenhouse gases in the atmosphere is increasing rapidly because of burning fossil fuels. To reduce future emissions, the electrification of offshore oil and gas installations is discussed. The ... -
FIELD-SCALE GENERALITY OF THE MACHINE LEARNING MODELS
(Master thesis, 2022)Drilling performance is directly related to fundamental aspects such as drilling variables that can affect the performance of the operation, the well stability, efficiency of drilling equipment, use of new technologies and ... -
Analyze Gelling Properties for Time-Dependent Non-Newtonian Fluids
(Master thesis, 2022)Drilling fluids are visco-elastic materials. This means that they behave as a viscous fluid when subject to sufficient shear stress and like an elastic solid when they are in near static conditions. Both properties are ... -

Underground Storage of Natural Gas in Aquifers by Using CO2 as Cushion Gas
(Master thesis, 2022)To satisfy energy demands, the natural gas supply must be smoothed. This aim can be accomplished by means of underground natural gas storage. They provide large-scale seasonal storage of natural gas. To maintain reservoir ... -
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 ... -
Comparison Between a Numerical Model and an Analytical Model for Drag Prediction
(Master thesis, 2022)High torque and drag create problems in directional wells. Directional wells have increased in inclination and length over the years, whereas the extended reach wells (ERW) are particularly prone to torque and drag ... -
Portfolio Optimization of Investment in Hydrocarbon, Renewable, and CCS

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 ... -

Fluid-Rock Interactions for CO2 Geological Storage in Chalk
(Master thesis, 2022)CCS has been recognized as an effective strategy to limit the temperature rise to 1.5 °C by 2050 under the Paris Agreement. As a result, more than 50 CCS pilot or large-scale projects have been commissioned in recent ... -
A pore-to-core scale investigation of hysteresis for CO2 storage processes using a discrete-domain method
(Master thesis, 2022)In this thesis we have studied a discrete-domain method that is implemented to demonstrate the immiscible, two-phase displacements of two fluids, namely CO2 and water (or brine) in an originally water-saturated reservoir ... -
Wellbore stability analysis for an extended-reach well on Ekofisk

Simulation Study and Modelling Improvements for the Bullheading Process
(Master thesis, 2022)In a bullheading operation, selecting the right pumping rate is vital to the job's success. A too low pumping rate may not displace the undesired fluid back into the formation, and a too-high rate generates high surface ... -
Estimation of the Free Rotating Hook Load for WOB Estimation
(Master thesis, 2022)Today’s drilling industry emphasizes safety and deeper drilling while reducing drilling costs. Low rate of penetration (ROP) and non-productive time are two main reasons for reduced drilling efficiency. Machine Learning ... -
Reservoir simulation of measurements with an innovative tool to detect oil-water-contact
(Master thesis, 2022)Hydrotell is developing a tool which will measure the pressure difference between oil phase and water phase in reservoirs with hydraulic conductivity. This pressure difference is then used to locate the free water level ...
