(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)Macondo blowout also known as the Deep Water Horizon incident has been one of the biggest oil field disaster in history. It has also become an effective case study for the Health Safety and Environmental aspects of the ... -
Gas condensate field performance theory vs practice
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012-06)This report presents a study on how to represent wells in numerical simulation of a coarse-gridded, full-field study of a lean gas condensate reservoir. A "black oil" (formation volume factor representation of fluid ... -
Gas Hydrate Growth Kinetics ; Experimental Study Related to Effects of Heat Transfer
(PhD thesis UiS;335, Doctoral thesis, 2017-02-16)Gas hydrate thermodynamics and phase equilibria is already well established. However, some knowledge gaps still need to be filled in gas hydrate growth kinetics, in relation to new gas hydrate based technologies in gas ... -
Gas Hydrate Growth Kinetics: A Parametric Study
(Journal article; Peer reviewed, 2016-12)Abstract: Gas hydrate growth kinetics was studied at a pressure of 90 bars to investigate the effect of temperature, initial water content, stirring rate, and reactor size in stirred semi-batch autoclave reactors. The ... -
Gas in overburden on Ekofisk
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)The Ekofisk field is a large producing oil and gas field located in the southern part of the Norwegian sector of the North Sea. The production started in 1971. During the production, the reservoir has been decompressed ... -
Gas lift simulation and experiments in conjunction with the Lyapkov P. D. methodic
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-13)The present Master’s thesis reports the study of continuous gas lift for a production oil well. The objective of the present work is a better understanding of processes occurring in a gas lift well, as well as optimization ... -
Genuine two-phase flow dynamics with a free interface separating gas-liquid mixture from gas
(Journal article; Peer reviewed, 2013)This paper deals with a two-phase compressible gas-liquid model relevant for modeling of gas-kick flow scenarios in oil wells. To make the model more realistic we include a natural pressure-dependent well-formation ... -
