An Experimental Study of Fluid Displacements and Effects of Inner Pipe Vibration in an Eccentric and Vertical Annulus
(Master thesis, 2021)Well abandonment operations can be expensive and time consuming, and thousands of wells will need to be permanently plugged and abandoned off the coast of Norway in the coming years. One potential cost-cutting measure ... -
An experimental study of unsupported pipe buckling in live well intervention
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)In this experimental study, unsupported pipe experiments are conducted. Information regarding intervention operation, focusing on snubbing operations in live well interventions and unsupported buckling during these operations, ... -
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 Overview and Discussion of MPD Systems used in Offshore Operations
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Globally, established fields are reaching maturity and easily accessible reserves have already been exploited. The remaining reserves are generally more difficult to drill and attempting to drill them using conventional ... -
Analysis for model verification of Torque, Drag and Hydraulic Modules in Oliasoft Welldesign Software
(Master thesis, 2022)Drilling through the subsurface is a complicated process that frequently results in technical challenges. Understanding and anticipating drilling problems, as well as their causes and planning remedies, are essential for ... -
Analysis of flame propagation using an imaging technique BOS (Background Oriented Schlieren) and PIV (Particle Imaging Velocimetry).
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)An experimental and simulation work has been conducted to study premixed flame propagation using imaging technique BOS (background oriented schlieren) and PIV (particle imaging velocimetry). Flame images obtained from ... -
Analysis of lost circulation on the Norwegian Continental Shelf
(Master thesis, 2021)Lost circulation (downhole losses of drilling fluid) is defined by the absence or reduction of drilling fluid pumped through the drill string while drilling the wells, which filtrates the formation instead of flowing up ... -
Analysis of pore pressure measurements in exploration wells in the Norwegian North Sea
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-12)The aim of this thesis was to examine the pore pressure measurements in the Norwegian North Sea. To study the possibility of the overpressure being an indicator that can increase the probability of hydrocarbon discoveries ... -
Analysis of Wired Drill Pipe Data and Cuttings Transport
(Master thesis, 2023)The prime objective of all oil and gas companies are to conduct various activities in a safe and cost-efficient manner, while also paying attention to the long-term integrity of the wells. To overcome challenges with reduced ... -
Analysis of Wired Drill Pipe data while using the Controlled Mud Level technology
(Master thesis, 2021)Managed Pressure Drilling (MPD) methods are used to drill wells with narrow pressure margins in a safe, efficient, and economical way. Controlled Mud Level (CML) is a dual-gradient MPD technique which is found effective ... -
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 ... -
