An Experimental Study of Vibration Assisted Displacement in a Horizontal Annulus for Enabling Through Tubing Abandonment
(Master thesis, 2021)Traditionally, Permanent Plug and Abandonment (PP&A) operations has been carried out by pulling casing and tubing using either Mobil Offshore Drilling Unit (MODU) or Fixed Platform Drilling (FPD). The costs can run up to ... -
An Experimental Study of “Heavy over Light” Density-Unstable Displacement of Newtonian Fluids in a Vertical Annular Geometry of Interest to Reverse Circulation Cementing
(Master thesis, 2021)When an oil well is constructed it is important to cement the casing in place.The cement’s main objectives is to support the casing and ensure zonal isola-tion to prevent leakage of reservoir fluids to the surface. Primary ... -
An Experimental Study on the Rise and Absorption of CO2 Bubbles in Newtonian and non-Newtonian Fluids
(Master thesis, 2023)CO2 released from combustion of carbon or hydrocarbons has the potential to be stored in oceans or water based systems. Optimizing this process requires collecting comprehensive data with varying parameters to gain a deeper ... -
An Experimental Study on Thermophysical Parameters of Production Wells and their Applications
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Transient pressure and temperature behavior in a wellbore develops as hot fluids from the reservoir move upward, exchanging heat with the surrounding formation. Because of heat exchange between the production fluid and ... -
An exploration of combinatorics and combinatorial geometry from a pedagogical perspective
(Master thesis, 2023)This thesis explores combinatorics and combinatorial geometry and how it can be used in the classroom, with a particular focus on using these sorts of tasks with younger students. There are 4 different types of combinations ... -
An exploratory case study on the opportunities of how Artificial Intelligence can contribute to reduce the communication gap and streamline the distribution of resources.
(Master thesis, 2022)Executing a project successfully requires companies to initiate the right processes and implement the correct tools. Project management depends on good planning to achieve its strategic goals. It is necessary to have ... -

An exponential time-differencing method for monotonic relaxation systems
(Journal article; Peer reviewed, 2014)We present first and second-order accurate exponential time differencing methods for a special class of stiff ODEs, denoted as monotonic relaxation ODEs. Some desirable accuracy and robustness properties of our methods are ... -
An Improved Basis for Estimating Riser Leak and Damage Frequencies
(Masteroppgave/UIS-TN-ISØP/2019;, Master thesis, 2019-07-03)In the petroleum industry, risers are widely used to transport fluids and gases. Risers are intended to be critical integral components as they are subjected to numerous failure factors, where in case of a leak, a highly ... -
An improved cement slurry formulation for oil and geothermal wells
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Properly designed cement slurry and good cement job are crucial factors for integrity during a well‘s life cycle. For this, cement must be able to prevent migration of formation fluids, support the well construction and ... -
An Improved Correlation Approach to Predict Viscosity of Crude Oil Systems on the NCS
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)An accurate estimation of viscosity values is imperative for an optimal production and transport design of hydrocarbon fluids. Based on this requirement, cost efficient and reliable empirical correlation models are highly ... -
