Weight Margins and Flexibility in Offshore Rigs
(Master thesis, 2013)The subject of this paper is the use of weight margins in the design and fabrication of large offshore oilrigs. Margins are a way of increasing the freedom of choice of the designers and a method of increasing the overall ... -
Weightless Neural Network-Based Detection and Diagnosis of Visual Faults in Photovoltaic Modules
(Peer reviewed; Journal article, 2023)The present study introduces a novel approach employing weightless neural networks (WNN) for the detection and diagnosis of visual faults in photovoltaic (PV) modules. WNN leverages random access memory (RAM) devices to ... -
Weinberg’s 3HDM potential with spontaneous CP violation
(Peer reviewed; Journal article, 2023)We study the potential of Weinberg’s Z2 × Z2-symmetric three-Higgs-doublet model. The potential is designed to accommodate CP violation in the scalar sector within a gauge theory, while at the same time allowing for natural ... -
Welding mechanism and welding quality in extrusion welding
(Master thesis, 2010)A short theoretical foundation is presented that covers; heat treatment of aluminium to T6 condition, a brief overview of conditions that affect extrusion welding in aluminium and a few well-known methods for mechanical ... -
Welding on Power Pylons in Aluminium
(Master thesis, 2016)This master thesis has investigated the behaviour of aluminium cylinders subjected to compression for both unwelded and welded cross sections. Three different combinations of material and geometry has been tested in the ... -
WELDSIM Simulations of Alu-Steel Butt Welds Produced Using the Hybrid Metal Extrusion and Bonding (HYB) Process
(Master thesis, 2020)Hybrid metal extrusion and bonding (HYB), er en fast fase sammenføynings prosess. Først utviklet for sveising av aluminium. Men også kapabel til å sveise ulike metaller. Prosessen bruker tilføring av materiale ved hjelp ... -
Well Control Aspects of Riserless Drilling
(Master thesis, 2013)This master thesis has investigated feasibility of effective well control in riserless drilling. An attempt was undertaken to design a realistic model of riserless well using advanced multiphase simulation tool and evaluate ... -
Well Control Optimization by Coupling Smart Proxy Models with Genetic Algorithm
(Master thesis, 2021)Generally, optimal well controls to maximize net present value (NPV) are obtained by coupling of numerical reservoir simulation with an optimization algorithm. This approach requires a significant number of numerical ... -
Well Control Optimization in Waterflooding Using Genetic Algorithm Coupled with Machine Learning Models
(Master thesis, 2020)Generally, optimum well controls to maximize net present value (NPV) in a waterflooding operation are obtained from a numerical reservoir simulation in combination with an optimization algorithm. This procedure is often ... -
Well control with Controlled Mud Pressure: Reviewing AGR’s well control procedures for the CMP system, analyzing and comparing with conventional well-control procedures, possible impact of technology.
(Master thesis, 2011)Dual Gradient Drilling (DGD) are a portfolio of drilling systems that in various ways pumpreturns from the well through a mud return line (MRL) from the seafloor, or somewhere between the seafloor and the rig floor. Two ... -
Well control with Low Riser Return System
(Master thesis, 2011)A response to the increasingly more challenging prospects to drill, due to depletion of old reservoirs and increasing water depths, is the Low Riser Return System (LRRS). The LRRS is a system designed to manage the wellbore ... -
Well Integrity Assessment: Challenges related to Human and Organizational Factors - The case study of Veslefrikk
(Master thesis, 2015)Well integrity affects safety, humans, the environment, production, reputations and assets value. The concept of well integrity in relation to human and organizational factors have gained considerable attention in the ... -
Well Integrity behind casing during well operation.Alternative sealing materials to cement
(Master thesis, 2013)Maintaining well integrity during all well operations has become a major concern for operators worldwide. The maintenance of an increasingly aging well stock and the higher cost associated with new wells makes well integrity ... -
Well Log and Seismic Data Interpretation: Rock Physics Study of Poorly Consolidated Sandstones in The North Sea
(Master thesis, 2012)We use rock physics models for poorly consolidated rocks to diagnose reservoir sandstones in the Alvheim Field, North Sea. Geological factors that will control the rock physics and seismic properties include clay content, ... -
WELL LOG ZONATION AND CORRECTION BASED ON VARIATIONS IN AMPLITUDE AND LAYER THICKNESS
(Master thesis, 2011)Well log zonation is the usual practice to carry out well log analysis. Definition of bed boundaries at a very detailed level is difficult and time-consuming, and therefore some data is frequently untapped, especially when ... -
Well Path Optimization on a CO2 EOR Project
(Master thesis, 2019)Optimering er eit heller nytt emne i petroleumsindustrien, men har i det siste sett auka interesse. Innanfor EOR, eller Enhanced Oil Recovery, kan optimeringstilnærmingar bli implementert for meir fordelaktige brønnbanar. ... -
"Well Placement for maximum production in the Norwegian Sea": Case Study: Norne C-segment Oil Field
(Master thesis, 2012)In petroleum fields, the essence of well placement is to develop and maintain petroleum reservoirs in order to achieve maximum production for economic benefit. Maximum production can be achieved with more oil wells, but ... -
