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 ... -

(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)The Kerpini Fault Block is located in the southern part of the Gulf of Corinth rift system. The rift system consists of several east-west orientated half-grabens with associated syn-rift sediments. Kerpini Fault Block is ... -
Geological mapping of the south-central Gulf of Corinth coastal fault system - Greece
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)This thesis is related to geological mapping of the south-central Gulf of Corinth (Greece), providing an interpretation for the major fault systems towards the east and the west of much studied coastal fault segments: ... -
Geophysical analysis in the Grane Area
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)Conventional seismic stack are not very efficient to delineate the hydrocarbon bearing interval within the Lower Heimdal sandstones in the Grane area, as the reflectivity of top Lower Heimdal are subtle. This becomes more ... -
Geopolymering av norite
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-07-29)This thesis on ‘’Geopolymerization of Norite’’ has been a study of plugging materials for plug and abandonment operations, and the different requirements for plug and abandonment operations based on Norsok D-010 standard. ... -
Global weak solutions for a compressible gas-liquid model with well-formation interaction
(Journal article; Peer reviewed, 2011-10)Abstract. The objective of this work is to explore a compressible gas-liquid model designed for modeling of well °ow processes. We build into the model well-reservoir interaction by allowing °ow of gas between well and ... -
Global weak solutions for a gas liquid model with external forces and general pressure law
(Journal article; Peer reviewed, 2011)In this work we show existence of global weak solutions for a two-phase gas-liquid model where the gas phase is represented by a general isothermal pressure law, whereas the liquid is assumed to be incompressible. To make ... -
Gravel packing methods in long blank sections with near vertical regime in openhole
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)Gravel packing is a well-known method in sand control where stabilizing the formation with gravel prevents the production of formation sand. Longer and more complex completion operations are making the business of ... -
Hafnium isotope geochemistry on detrital zircons in Mesozoic succession of the Barents Sea to enhance the provenance knowledge of potential Hydrocarbon reservoir succession.
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-02-13)Technological advances have led to the development of various methods that allows us to more accurately pinpoint the timing of geological events using geochronology. One of the most established and acknowledged techniques ... -
Heat Recovery Mechanism for Non Condensable Geothermal Fractured Reservoirs by CO2 Injection and Well Heat Insulating
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)In this thesis we analyzed the potential use of operating geothermal plants with water and CO2 as working fluids using a geothermal simulator TOUGH2 module EOS1 and EOS2, respectively. We also studied the sensitivities of ... -
Heat transfer measurements in stirred, cylindrical cells containing ethylene oxide (EO) and tetra hydro furan (THF) hydrate – water solutions at temperatures between 1 – 4 °C as function of amounts and volume of hydrates present in the solutions.
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-30)It is believed that heat transfer plays a major role in hydrate formation, and is also dependent on the hydrate concentration. Heat transfer during hydrate growth is an important process, which deserves a great depth of ... -
Heave effects on Drill String during connections
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)During the make-up and break-out of the connections, the drill string is wedged in the rotary table and the top of the drill string follows the platform heave movement as the bit is off bottom. This oscillation may be ... -
