3D-modellering av løsmasser og potensiell kvikkleire i Orkdalen ved bruk av Leapfrog Geo
(Master thesis, 2023)Store deler av Orkdalen ligger under marin grense, hvor det potensielt kan forekomme kvikkleire. Uklarheter vedrørende dalens løsmassefordeling og utbredelse av kvikkleire medførte at Orkland kommune i 2021 initierte et ... -
4D rock physics and dynamic RPTs for sandstones
(Master thesis, 2010)We discriminate between static and dynamic rock physics templates, static RPTs relates the elastic properties of acoustic impedance and Vp-Vs ratio of the reservoir at fixed time in its history where dynamic RPTs relate ... -
4D seismic modelling on the Fangst reservoir onthe Heidrun Field: A quantitative approach of the fluid and saturation changes, and the relation to 4D-seismic
(Master thesis, 2011)Based on the pre production base surveys shot in 1986 and 1991, several repeated seismic surveys have been shot with the aim to monitor the fluid flow on the Heidrun Field offshore Mid-Norway. This is to better define ... -
4D tolkning av gassmigrasjon i grunne sandlag: sammenlignet med reservoar simulering
(Master thesis, 2011)The work done in this Master thesis is focused on an area influenced by an underground blow-out from Saga Petroleum ASAs 2/4-14 well. 2D seismic site surveys acquired before, during and after the blow-out took place have ... -
A better Horizon Auto Tracker - Powered by Machine Learning
(Master thesis, 2018)Computer-assisted horizon interpretation on 3D seismic data has been commercially available for almost 15 years. The process is generally referred to as 3D horizon autotracking and is a powerful method when interpreting ... -
A Case Study of How MPD Techniques Can Be Used to Adapt to Uncertain Pore and Fracture Pressure Gradients
(Master thesis, 2014)This thesis aims to identify the potential and limitations of using Managed Pressure Drilling (MPD) in deepwater fields where narrow and unpredictable mud weight windows are encountered. A significant effort has been done ... -
A Comparative Analysis of Rheological Characteristics of Polymer Solutions Exposed to Temperature and Stress Over Time
(Master thesis, 2017)A series of experiments with thixotropic fluids composed of polymers and salt, with various temperatures and in circulation was carried out to examine how it influenced the current polymers decompositioning. The results ... -
A Comparative Simulation Study of Chemical EOR Methodologies (Alkaline, Surfactant and/or Polymer) Applied to Norne Field E-Segment
(Master thesis, 2011)Primary and Secondary Recovery techniques together are able to recover only about 35-50% of oil from the reservoir. This leaves a significant amount of oil remaining in the reservoir. The residual oil left after the water ... -
A Comparative Simulation Study of Chemical EOR Methods Applied to the Norne E-Segment Using Eclipse 100
(Master thesis, 2014)Secondary recovery techniques such as waterflooding are often used to maintain pressure during depletion. Still, unfavorable mobility ratios, reservoir heterogeneity and strong capillary forces may cause a waterflood alone ... -
A Comparison of Analytical and Experimental Procedures to Verify a Lumped Drill String Element Model
(Master thesis, 2016)A study of axial vibrations in a vertical drill string is conducted using a spring-mass-damper model with n coupled elements. The main motivation behind this is to describe the axial vibrations using a simple mathematical ... -
