Intepretation, modelling, and halokinetic evolution of salt diapirs in the Nordkapp Basin
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)The Nordkapp Basin provides one of the examples of salt diapirism in the southwestern Barents Sea, becoming an area of interest for hydrocarbon exploration during the last 30 years. Several exploration wells have been ... -
Interactions between CO2 and cap rock during CO2 storage
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Geological sequestration and storage of carbon dioxide is a viable method for mitigating anthropogenic emissions of fossil fuels into the atmosphere. Geochemical reactions play an important role in CO2 storage environments ... -
Interactions between CO2 and rock in heterogeneous reservoirs during CO2 storage
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Reactive transport simulations of CO2 storage in heterogeneous reservoirs are performed using the PHREEQC software by Parkhurst and Apello. When CO2 dissolves in the pore water carbonic acid is formed. These aqueous species ... -
Intermittent Water Injection on Top of Continuous CO2 Injection to Co-Optimize Oil Recovery and CO2-Storage
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)The objective of this project is to maximize oil recovery and the CO2 stored during CO2-EOR. To reach that goal there are two important things to be achieved: gas production rate reduction and the oil production rate ... -
Interpretation of Upper Jurassic sandstone in the area between Statfjord and Tordis field, Northern North Sea
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)The study area is located in the half graben between the Statfjord field and the Vigdis development on the Tampen Spur, northern North Sea. The petroleum systems in the central and northern North Sea are mainly Jurassic-sourced. ... -
INVERSION methods to determine the in-situ stresses
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-12)The challenges pose by the uncertainty in the in-situ stress measurement in the petroleum and mining industries are enormous. A handy computer tool to estimate the magnitude and direction of the horizontal in-situ stresses ... -
Investigation of Corrosion in Geothermal Wells - A Qualitative Risk Assessment
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)The petroleum industry uses a variety of qualitative risk assessment methods for maintaining well integrity, such as well barrier schematics and barrier diagrams. Identifying barriers and using well barrier schematics are ... -
Investigation of gas composition on production performance of J-shaped gas-lift well
(Master thesis, 2014-06-16)The J-shaped gas-lift well showed complex dynamic phenomena. The downward inclination of the J-shaped well introduces periodic waves over time as a result of mixing gas and liquid. This behavior introduces periodic ... -
Investigation of Leakage Paths in Well Abandonment
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)A large number of wells will have to be abandoned at the NCS and around the world. NORSOK D-010 states that a well that is permanently abandoned shall be abandoned with an eternal perspective and with zero leakage [1]. ... -
Investigation of mechanical property of aplite-based geopolymer for plug and abandonment
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Historically and up to date, ordinary Portland cement (OPC) or a slight variation is the most widely used material for permanent Plug & Abandonment operation. However, there are several challenges related to cement usage. ... -
