Analysis of 3D post-stack data from offshore east Scotland
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012-06-29)This study concentrates on reprocessing a cube of post-stack 3D seismic data from offshore East Scotland to improve resolution of the data. The main application of the reprocessing is to allow for a better interpretation ... -
Analysis of borehole failure related to bedding plane
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Borehole instabilities during drilling are more common in shale formations than in most other rock formations. Shale make up more than 80% of sediments and rocks in siliciclastic environments and about three quarters of ... -
Analysis of drill-string based on case study of ultra-deep drilling on Kola Peninsula.
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)The topic of the following project is devoted to the theme of drilling of the ultra-deep wells and in particular to the optimization of the length of dual aluminum-steel drill string as a one of the concept which have been ... -
Analysis of drilled wells on the Norwegian Continental Shelf (NCS)
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Safe drilling operations are a result of integrated geo-mechanical engineering and drillstring mechanical engineering. Torque and drag modeling is used by the oil and gas industry in all phases of drilling a well: Planning, ... -
Analysis of Factors Contributing to Long Term Shallow Gas Migration to Seabed in Surface Casing Annulus
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-07)A common observation is a low rate gas bubbling from the outside of the 20” surface casing on wells located in the Haltenbanken area on Norwegian Continental Shore. This phenomenon is known as long term shallow gas migration ... -
Analysis of Gas Hydrate Growth Models
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-28)The kinetic behaviour of gas hydrate formation of pure methane have been studied and predicted based on different models. Experiments have been conducted at different temperatures and stirring rate, and the measured results ... -
Analysis of packer forces in vertical wells and frictionless sail sections
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)New discoveries could represent challenges in many ways such as high pressures and high temperatures. The reservoir contains corrosive liquids that are being produced to the surface. Since the casing is expensive to replace, ... -
