A Literature Review and Transport Modelling of Nanoparticles for Enhanced Oil Recovery
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Nanotechnology has been envisioned to transform every sector of industries, particularly in the petroleum industry. Numerous researches, especially on nano-EOR, have been done in the past few years and shown promising ... -
A mathematical model for spontaneous imbibition as a recovery mechanism
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-04)Spontaneous imbibition is a process where the wetting fluid displaces the non-wetting fluid in a porous medium by means of capillary forces. Spontaneous imbibition plays a significant role in the recovery of hydrocarbons, ... -
A mechanical study of the effect of sulphate
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)In this study the presence of sulphate in seawater was examined from a mechanical point of view. As test material an outcrop chalk from the Hallembaye area in Belgium called Liegé was used. This is a high porosity outcrop ... -
A new double porosity fractal model for well test analysis with transient interporosity transfer for petroleum and geothermal systems
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-06)A new double porosity model for Naturally Fractured Reservoirs (NFRs) assuming fractal fracture network behavior and its solution is presented. Primary porosity is idealized as Euclidian matrix blocks (slabs or spheres) ... -
A Study of a Mathematical Model for Cancer Cell Growth in a Gel
(Master thesis, 2017-06-15)In this thesis, a mathematical model describing gel contraction is derived and studied. The mathematical model describes the process where cells are compressing the gel, and the model is therefore used to study the cell ... -
A Study of Interplay Between Capillary and Gravitational Forces with Application to Oil Recovery in Naturally Fractured Reservoirs
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Built on literature views and formulation of oil recovery characteristics, three cases of numerical simulation have been performed on core scale which are gravity drainage(GD) individually, capillary pressure driven ... -
A study of pressure decay in a closed CO2-water system
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Analytical and semi-analytical solutions to the diffusion equation have been obtained in an effort to model pressure decay in a closed CO2-water system. Various boundary conditions that include different physical effects ... -
A study of the diffusion coefficient term in counter current imbibition and its effect on production
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)It is believed that most reservoirs have at least some degree of fractures and spontaneous imbibition is considered to be one of the most important recovery processes in fractured reservoirs. The imbibiton process can be ... -
A study of two-phase drift-flux modeling in wells and corresponding slip relations
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)It was desired to investigate the two-phase drift-fl ux model's behavior in both steady-state and transient settings and shed some light on required slip relations. A numerical MATLAB model of the one-dimensional two-phase ... -
Adsorption of quinoline onto illite at high temperature in relation to low salinity water flooding in sandstone reservoirs
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Laboratory tests, as well as field tests, have shown that low salinity water flooding in sandstone reservoirs can improve the water wetness of the rock and thereby increase the oil recovery. Many mechanisms have been ... -
Alternative production scenarios of the Gyda field
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The Gyda field has been on stream since June 1990. Water injection commenced Feb. 1991. Currently Gyda is suffering from high water cuts. Having in mind that water injection is very costly, environmentally pollutant and ... -
An experimental study of low salinity EOR effects on a core from the Yme field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The best known proposed mechanisms for low salinity effect are fines migration, pH increase, double layer expansion and multicomponent ionic exchange (MIE). Even though many mechanisms have been proposed, none of them have ... -
An Improved Correlation Approach to Predict Viscosity of Crude Oil Systems on the NCS
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)An accurate estimation of viscosity values is imperative for an optimal production and transport design of hydrocarbon fluids. Based on this requirement, cost efficient and reliable empirical correlation models are highly ... -

Clay minerals in sandstone reservoirs: implications for "smart water" injection
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)Clay minerals as ubuquitous in sandstone reservoirs, yet many of their effects are not well understood. This literature study examines the relationship between the most common clay minerals and smart water injection in ... -
CO2-foaming agent retention in fractured chalk models: Experiments and simulations
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Injection of CO2-gas can improve the oil recovery. In naturally fractured reservoirs such as chalk, injection of CO2-gas can result in early gas breakthrough because the gas can use the fractures as pathways from the ... -
Compositional simulations of producing oil-gas ratio behaviour in low permeable gas condensate reservoir
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-11)Gas condensate flow behaviour below the dew point in low permeable formations can make accurate fluid sampling a difficult challenge. The objective of this study was to investigate the producing oil-gas ratio behaviour ... -
