Investigation of torsional drillstring motion using finite element model
(Master thesis, 2021)In the thesis , a four degree of freedom dynamic drill string model suitable for prediction of self-excited torsional vibrations is modeled using the finite element method. The drill string equation of motion subjected to ... -
Reinforcement Learning for Automated Power Grid Operation: Can a machine be trained to operate a power grid?
(Master thesis, 2021)The increasingly high demand and amount of renewable energy sources in the power grid have added more complexity to power grid operations. The electrical power system must ensure that the generated power and the consumed ... -
Low- versus high-resolution assessment of reservoir compartmentalization in the Wisting field, Norwegian Barents Sea.
(Master thesis, 2021)Wisting is Norway’s northernmost oil field under development. With ~500 mmboe in shallow marine to fluvial Upper Triassic to Middle Jurassic reservoirs, which are highly faulted and just 250-300 m below sea bottom, this ... -

(Master thesis, 2021) -
Investigating the Effect of Injection Rate and Oil Viscosity on Oil Recovery during Waterflooding
(Master thesis, 2021)For over a century, waterflooding of oil reservoirs have been performed to improve oil recovery for two reasons: to provide pressure support to the reservoir and to displace the oil entrapped in the pores of the rock. ... -
Machine Learning techniques for Prediction of Rock Properties from Reservoir Well Logs
(Master thesis, 2021)Estimation of reservoir parameters is important in reservoir evaluation and estimation of petroleum volume. Reservoir parameters such as oil saturation, water saturation and porosity are derived from petrophysical logs or ... -
Predicting appointment attendance at an outpatient clinic
(Master thesis, 2021)Abstract Background and aim: No-show, refers to patients who do not show up in the scheduled appointment, which is a serious problem for many years in the hospital. Also, the no-show rates differ in countries because of ... -
A study of machine learning models application for porosity prediction using petrophysical well logs. Case Study: The Brent Group – Statfjord field
(Master thesis, 2021)The use of machine learning algorithms for predictive analytics is making a growing impact in the field of petroleum geosciences. With the increasing cost and time-related factors for obtaining accurate porosity measurements ... -
Optimization of a smart water composition for Enhanced Oil Recovery study by wettability alteration in carbonates at high temperature.
(Master thesis, 2021)Seawater due to its wettability modifying qualities has proved to be an excellent injection fluid in chalk. At high temperature seawater alter wettability towards more water-wet conditions thus improving the overall oil ... -
Machine learning based shale volume prediction from the Norwegian North Sea
(Master thesis, 2021)Petroleum geosciences, like other fields, has entered the era of new advanced technologies to handle problems related to complex massive data sets and decision making. The growing quantity of subsurface datasets has created ... -
Geometrical and kinematical analysis of an extensional fault-propagation fold in the Wisting Field, Norwegian Barents Sea
(Master thesis, 2021)The Wisting field is located on the Bjarmeland Platform northeast of the Maud Basin and adjacent to the Hoop Fault Complex. It is Norway’s northernmost oilfield to be developed. 3D high resolution P-Cable seismic data from ... -
Halokinesis influence on the Triassic deposition and the evolution of minibasins in the Central North Sea
(Master thesis, 2021)The main focus of this study is to improve the understanding about the lateral variation of the Zechstein Group and the impact on the Triassic sedimentary minibasins. The study area is located approximately 225 km south-west ... -
Causal Inference of Interwell Connectivity
(Master thesis, 2021)Interwell connectivity is a measure of the degree to which information is translated between wells in a reservoir. The translated information may include changes in pressure, fluid flow, or other physical properties. This ... -
Topology Optimization Using the Lattice Boltzmann Method
(Master thesis, 2021)Human design is limited by our ideas of geometries. Topology optimization is a tool to cross that barrier and improve design especially for applications that are irrevocable once they are in use. This thesis presents a ... -
Tertiary Tectonostratigraphic Evolution of the Veslemøy High and Central Part of the Sørvestsnaget Basin
(Master thesis, 2021)Previous geologically works in Sørvestsnaget Basin and Veslemøy High region, suggest that Tertiary reservoirs in the western Barents Sea are promising, but not yet properly understood laterally, with the influence of ... -
Machine and Deep Learning for Lithofacies Classification from Well Logs in the North Sea.
