Drilling Optimisation on the Norwegian Continental Shelf: Opportunities in Well Design Practice
(Master thesis, 2018-04-17)The purpose of this thesis was to attempt to provide evidence that Norway’s drilling fraternity is long overdue for a re-think in the way it drills wells. In so doing, the author has chosen to focus on slim well drilling ... -
Dry reforming of methane over Ni-Fe bimetallic catalyst
(Master thesis, 2021)Our climate is changing for the worse as the concentration of greenhouse gases in the atmosphere increases. Climate change is one of the most important challenges of our time. Emissions of greenhouse gases (GHG) have been ... -
Dynamic Acceptance Criteria for Periodic Testing of Downhole Safety Valves
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-06-15)Downhole Safety Valves (DHSVs) are periodically leak tested as part of the preventative maintenance program on an oil and gas producing facility. The last couple of years, the oil and gas industry on the Norwegian Continental ... -
Dynamic modelling of ram BOP
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018)As the closing time of Blowout Preventer rams is safety critical, this thesis proposes a dynamic model to calculate the closing time of a ram Blowout Preventer. The thesis work includes guidelines to recreate such a model ... -
ECD management and monitoring using High-Speed Wired Drill Pipe Telemetry in a Norwegian Offshore Well
(Master thesis, 2023)Mud weight, or as referred to in this paper as Equivalent Circulating Density, is a crucial element in sustaining wellbore stability and preventing drilling-related issues and has historically been difficult to monitor, ... -
Effect of 15nm SiO2 Nanoparticles on Enhanced Oil Recovery and Drilling Fluid: Experimental and Simulation studies
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Nanotechnology is among the most remarkable technology in the modern science, and due to unique and unrevealed abilities the tiny size of particles possesses, this technology has also been questioned in order to be worthy. ... -
Effect of Al2O3 nanoparticle, Silica Powder microparticle, and Fibers on the newly formulated geopolymer: Experimental and Modelling Studies.
(Master thesis, 2023)When the productivity of a reservoir becomes uneconomical, the final fate of the well is to be plugged and abandoned. NORSOK D-10 defines the well integrity criteria and sets criteria for cement properties to reduce the ... -
