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. ... -
Investigation of temperature- and pressure effects on drilling fluid properties and related downhole torque and drag calculations
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Increasing temperature and pressure with depth, affects the properties of drilling fluid. The effect of temperature and pressure on the density and viscosity of drilling fluid is of great importance. This is because, among ... -
Investigation of the transport mechanism of the cutting transport in drilling horizontal wells using high speed camera and PIV for analysis
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Dynamical feature of particle dunes is investigated in a horizontal drilling well. Apparently, it is quite challenging to transport the cuttings in horizontal section of the well because the cuttings tend to settle down ... -
Investigation of transient scenarios in underbalanced drilling
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)When drilling underbalanced wells, the standard way consists to drill with a very low mud weight in order to obtain a well pressure lower than pore pressure. The flow of the fluids from the reservoir up to the tubing is ... -
Investigations of a drilling operation by using a simplified gas-liquid mathematical model
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-05-22)There was a strong wish to investigate the physics of fluid flow involved in drilling operations where nitrogen injection is used to lower the hydrostatic pressure. This work is based on a reduced version of the full ... -
Kalavryta and Kerpini Fault Block: Investigation into correlation and nature of sub-horizontal layers; Corinth Graben, Greece.
(Master thesis, 2015-06)The Gulf of Corinth is located in West-Central Greece and is the result of a Pliocene-Recent, asymmetric extensional rift system. The region offers an excellent opportunity to study rotated fault blocks and the various ... -
Key criteria for successful LNG market development to replace LPG in the Scandinavian market.
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)The main goal of the thesis is to perform the comparative study of LNG and LPG markets and to examine key factors for successful LNG implementation on the Scandinavian market on competition with LPG. It was found that the ... -
Laboratory evaluation of sodium silicate for zonal isolation
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)A common problem for maturing oil fields is excessive water production. Ultimate oil recovery could be increased considerably by implementing an appropriate water production management. Solutions for managing excess water ... -
