Twisted Elliptic Cylinder of Uncertainty: An Alternative Method to Calculate the Anti-Collision Safety Factor
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-12-04)A precise anti-collision analysis is becoming even more important in the past few years, with the increasing amount of wells being drilled in highly congested fields. The costs associated with the production fields have ... -
Uncertainty analysis of Supervised machine learning predictions applied to Lithology classification
(Master thesis, 2022)Geosteering is the technique of guiding directional drilling to remain within the pay zone. This process demands a thorough survey of the lithological properties of the surrounding geo- logical strata. Since logging while ... -
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 ... -
Understanding Leakage Rates in Permanently Abandoned Wells by Studying Natural Hydrocarbon Seepages
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Permanent plug and abandonment (PP&A) of wells is steadily becoming more important on the Norwegian Continental Shelf (NCS), as a large number of fields are approaching end of their productive life. Combining operational, ... -
Undersøking av egenskapene til Polyanionisk Cellulose blandet med vann som sirkulerer gjennom en strømningssløyfe
(Bachelor thesis, 2021)Denne oppgaven er strukturert i to hoveddeler. Den første delen omhandler noen fundamentale roller borevæske har under boring. Det er i hovedsak fokusert på sirkulasjonssystemet i en boreoperasjon, hovedegenskapene til ... -
Use of the Quemada Model for Modelling Viscous Behaviour of Drilling Fluids.
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-15)Drilling fluids are essential for drilling operations and serve many important functions. To maintain control of the wellbore, while ensuring sufficient cutting transportation, good understanding of the rheological properties ... -
Using ceramic discs to evaluate fluid loss and formation damage
(Bachelor thesis, 2021)To prevent kicks and possible blowout of the well, the pressure from the drilling fluid must be kept above the pore pressure of the formation. This differential pressure forces the fluid into the porous formation, which ... -
Utvikling av ny tetthets - hastighet og kompresjon - skjærbølgehastighetsmodell basert på NCS-feltdata: Empirisk og kunstig neuronettverksbasert
(Bachelor thesis, 2021)Denne oppgaven presenterer utviklingen av nye tetthet- og hastighets- regresjonsmodeller (enkel- og multivariate-baserte) og artificial neural network (ANN) basert modellering ved bruk av data hentet fra Barentshavet, ... -

Value of Digitizing Well Interventions and its impact on business and working processes
(Master thesis, 2021)The oil and gas industry continuously enters a phase with new challenges and new ways of thinking, the rise of a digitalization revolution can be the key answer to creating new opportunities to overcome the industry's ... -
Value of Information Analysis in CO2 Sequestration Projects
(Master thesis, 2021)As one of the main risks related to CO2 storage is leakage, it is important to consider the impact of the reservoir uncertainties on the long-term CO2 migration and leakage which affecting the decisions in CO2 storage ... -
Valuing abandonment decisions: Maximizing an oil and gas fields Net Present Value
(Master thesis, 2021)The oil and gas sector in the North Sea is mature and consists primarily of brownfields that have passed their peak production or are close to the end of their lives. Many of these fields will have to be abandoned in the ... -
Wall Temperature Analyses of Sandwiches Sections Using Infrared Thermography to Evaluate Micro-Annuli size
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-15)This study mainly focuses on the detection and characterization of micro-annuli at the interface of cement and casing, usually caused by changes in pressure, temperature, or volume change of zonal isolation material. For ... -
Water flooding of Eldfisk reservoir cores
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)Enhanced Oil Recovery (EOR) and the effect of the aqueous chemistry on the mechanical strength of chalk have been extensively studied over the years. This is simply because the stability of the reservoir system is affected ... -
Water Injection in Wisting - importance of barrier management
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-07)A preselected Wisting well injector design has been used as a basis for this study. Because of the challenges following an ultra shallow reservoir and an almost negligible stress contrast between the reservoir and cap rock, ... -
Well Barrier Restoration Across Dual Cemented Liners
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)In the past years there has been an increased focus on decommissioning of wells in the NCS. Decommissioning of wells introduces significant investments with no financial returns and has for those reasons historically had ... -
