Applications of condition monitoring for the subsea industry
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)With the increased interest in developing offshore fields by subsea completions, also comes the need for minimizing the non-productive time of these systems caused by unexpected failures and lengthy repairs. Maintenance ... -
Applications of machine learning in petroleum system characterization using mud gas data
(Master thesis, 2022)Mud gas data are continuous measurements of the different compounds of the gas released from the formation while drilling. While these data are cheap and extensive, as they are always recorded for safety reasons, they are ... -
Applied well integrity
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)Extended reach drilling is the result of industry focus to exploit fields efficiently with a minimum financial and environmental impact. Two of the ERD pioneer fields are Wytch Farm in UK and Statfjord on the Norwegian ... -
Applying a machine learning method for cumulative fatigue damage estimation of the IEA 15MW wind turbine with monopile support structures
(Peer reviewed; Journal article, 2023)Offshore support structures are critical for offshore bottom-fixed wind turbines, as they bear nearly all the mass and loading of wind turbine systems. In addition, the support structures are generally subjected to a harsh ... -
Applying dual gradient drilling in complex wells, challenges and benefits
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06)Dual gradient drilling is a manage pressure drilling technique that may extend viability of deep and ultra- deep water drilling and production, in a manner that may be classified as safe or safer, than what can be achieved ... -
Applying GARCH in value-at-risk estimation of market risk
(Master thesis, 2017-06-14)This thesis tests the correlation between four commodities and eight stocks of companies consuming or producing the commodities. The commodities include oil, gas, salmon and aluminum, while the stocks are Statoil, Seadrill, ... -
Applying Geological Process Modeling to a turbidite system in the northern North Sea
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)In recent years, several mathematical methods, especially those based on geostatistics, have been used in reservoir characterization. The reliability of the static models derived from these techniques depends on available ... -
Applying machine learning and deep learning algorithms to classify patients using EEG signals.
(Master thesis, 2023)This thesis investigates the potential of Event-Related Potentials (ERPs) for subject-group classification. The ERPs data from five distinct subject groups are analyzed to evaluate the discriminatory power of ERPs in ... -
Appraisal campaign selection based on the maximum value of sequential information
(Peer reviewed; Journal article, 2021-09)Field development projects generally demand large investments which are subject to geological uncertainty, hence projects can benefit from geological information obtained from appraisal wells before large capital commitment. ... -
Appraisal of riser concepts for FPSO in Deepwater
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-30)With oil and gas reserves moving into deeper waters Floating Production Units (FPUs) have been widely used for production purpose. Selection of FPU for deepwater field development is a complicated task is mainly governed ... -
An approach for optimization of controllable drilling parameters for motorized bottom hole assembly in a specific formation
(Peer reviewed; Journal article, 2023)This study focuses on optimizing drilling parameters when using Positive Displacement Motors (PDMs). In drilling operations involving mud motors, weight-on-bit (WOB) alterations lead to variations in the system's parasitic ... -
An Approach to Determine Optimal Bow Configuration of Polar Ships under Combined Ice and Calm-Water Conditions
(Peer reviewed; Journal article, 2021-06)Selecting an optimal bow configuration is critical to the preliminary design of polar ships. This paper proposes an approach to determine the optimal bow of polar ships based on present numerical simulation and available ... -
