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 ... -
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 ... -
Low salinity effect after sea water flooding in sandstone reservoirs
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Clays are the main wetting minerals and have permanently negative surface charges. The negative charges must be balanced by; active cat ions, polar components or H+. pH changes is observed in the effluent by flooding in ... -
LWSF simulation at larger scale
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Low salinity water flooding is a field of science that is new and need more research to find a definite theory of what happens. There have not been done many modeling studies on this field. The objective of my thesis ... -
Mathematical modeling of water-rock chemistry during water injection and its impact on the composition and porosity of chalk

Modeling of dirty sands and clay zones with poor production characteristics
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The Statfjord field is one of the oldest and largest oil and gas producing fields on the Norwegian continental shelf. It is currently at its late life production period with pressure depletion as the main production ... -
Modelling of gas production from tight shale formations: An innovative approach
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)Shale gas is one of the most rapidly growing forms of natural gas. Unconventional natural gas deposits are difficult to characterize overall, but in general are often lower in resource concentration and more dispersed over ... -
Modelling of water-oil flow in reservoirs including effects from gravity, capillary pressure and water rock chemistry
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-07-01)In this work we use mass balance equations to arrive at a classical description of the Buckley-Leverett equation for two phase flow in a one dimensional porous medium. Through the use of explicit numerical techniques we ... -
Models for water flooding, imbibition and coupled fracture-matrix flow in a fractured reservoir
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)The study of reservoir performance during waterflooding is important to reservoir engineers. Numerous analytical, semi-analytical and numerical flow models with different assumptions have been submitted over the years, ... -
Numerical simulation of co-current and counter-current imbibition
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Spontaneous imbibition (SI) is a very important mechanism for oil recovery in naturally fractured reservoirs. Several studies have indicated that counter-current oil production is much slower and give lower ultimate oil ... -
Numerical simulation of surfactant flooding in mixed wet reservoirs
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Surfactants have been considered for enhanced oil recovery either by reduction of oil–water interfacial tension (IFT) or through wettability alteration. This study reveals the effect that reduced interfacial tension has ... -
Permeability modeling of Lavrans field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Permeability has been calculated for three exploration wells from the “Smørbukk” field, from the mid – Norwegian Sea. Permeability from logs, cores and cross plots have been derived and compared with permeability from well ... -
Reservoir Characterization of the Skagerrak Formation
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)A petrophyscial evaluation has been generated for three wells penetrating the Skagerrak Formation in the Sleip ner Øst field, the Gungne field, and the Loke field in the Central North Sea, Figure 5 - 1. ... -
