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 ... -
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 ... -

Effect of barium and strontium on low salinity waterflooding
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-27)Much work has been done on the subject of low salinity waterflooding (LSWF) as a potential enhanced oil recovery method. It has been shown many times that reducing the salinity of the injected brine could have a positive ... -
Enhanced oil recovery (EOR) by "smart water" in carbonates reservoir
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-05-30)Characterization of the reservoir limestone cores has to be specified to obtain possible solution (designed water) based EOR technique to enhance the oil production. In this project a parametric study was performed to ... -
Evaluating the potential of low-salinity water flooding to enhance the oil recovery in limestone reservoir
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)In this project, the potential of low salinity brine to enhance the oil recovery has been studied. Four flooding tests were conducted both on limestone cores containing anhydrite and chalk core containing no sulfate. -
Evaluation of low salinity injection EOR potential in Johan Sverdrup Field
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017)Low salinity waterflooding is an EOR method that doesn’t get mentioned as much as other EOR methods in the current oil industry, but its recognition has been raised in the last few years and BP is also using their own low ... -
Evaluation of using Smart Water to enhance oil recovery from Norwegian Continental Shelf sandstone reservoirs.
(Master thesis, 2016-06-09)Recently, the scale of studies on smart water – one of EOR method - has increased. From decades, water flooding is one of the most used methods to increase oil recovery. However, more effective in sandstone reservoirs is ... -
Geochemical modeling of low salinity core flooding
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Extensive research the last decades has shown that lowering the salinity and ionic compostion of injection water can improve thre oil recovery. The mechanisms causing low salinity water to give favorable reservoir conditions ... -
Influence of Silica Based Nanofluid on the Physical Properties, IFT, and CO2 Diffusion in a Carbonated Water - n-decane system: An Experimental and Numerical Study
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Carbonated water injection (CWI) for enhanced oil recovery (EOR) overcomes mobility issues, macroscopic bypassing and sweep efficiency limitation of conventional CO2 injection. It might also lead to reconnection of trapped ... -
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 ... -
Mechanism of primary and secondary oil flooding for recovery from chalk by low
(Master thesis, 2014-06-16)This research work is performed with the intention to bring the contribution in the ongoing discussion of implementing the low salinity brines as the injection fluid in carbonate reservoirs. The work contains theoretical ... -
Mechanism of primary and secondary oil flooding for recovery from sandstone by low salinity water
(Master thesis, 2014-06-16)Low salinity water flooding (LSW) as an enhanced oil recovery (EOR) method has been discussed by many researchers, but consistent approved mechanism is still not found. The main reason of lack of clear understanding of the ... -
Micro- and nano-analyses of fracture-filling after flooding on-shore chalk with different IOR fluids
(Masteroppgave/UIS-TN-IER/2018;, Master thesis, 2018-06-22)Water injection into the Ekofisk-reservoir was introduced in 1987 to enhance oil recovery (EOR) dissolution and precipitation by exposing chalk to various brines at reservoir conditions, which further increased deformation ... -
Raman spectroscopy applied to enhanced oil recovery research
(Master thesis, 2015-06-09)It is well established that aqueous chemistry affects the mechanical strength of chalk. Seawater tends to weaken chalk at reservoir temperatures and consequently the recovery rate. As more than 50 % of the oil in existing ... -
