Effect of water-extractable carboxylic acids in crude oil on wettability in carbonates
Fathi, Seyed Jafar; Austad, Tor; Strand, Skule (Journal article, 2011)The acidic components of the crude oil have a profound effect on the initial wetting conditions and possible wettability alteration by seawater in carbonates. In this work, three types of crude oils with different ... -
The effects of pH, time and temperature on the stability and viscosity of cellulose nanocrystal (CNC) dispersions: implications for use in enhanced oil recovery
Molnes, Silje; Paso, Kristofer Gunnar; Strand, Skule; Syverud, Kristin (Journal article; Peer reviewed, 2017-08)Cellulose nanocrystals (CNC) are currently being investigated as potential additives for enhanced oil recovery (EOR). Presented in this paper is a study investigating the effects of different physical and chemical environments ... -
Enhanced oil recovery from Sandstones and Carbonates with “Smart Water”
Torrijos, Ivan Dario Pinerez (PhD thesis UiS;341, Doctoral thesis, 2017-03-31)According to the International Energy Agency crude oil is expected to contribute approximately with 26% of the world’s energy supply by 2040. In a per year basis, new oil discoveries have dropped to a 60-year low in 2015, ... -
Evaluation of Cellulose Nanocrystals as a Green "Smart Water" Additive in Enhanced Oil Recovery from Sandstone Reservoirs
Molnes, Silje Nedland (PhD thesis UiS;348, Doctoral thesis, 2017-06-15)Petroleum reservoir production is frequently supported by using flooding fluids, and offshore this fluid will very often be seawater. The efficiency of this water injection is affected by various factors, such as the ... -
Evaluation of low salinity injection EOR potential in Johan Sverdrup Field
Fang, Wei (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.
Piotrowska, Natalia (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 ... -
Smart Water injection into sandstone reservoirs for enhanced oil recovery - Influence of oil components on sandstone wetting
Kinn, Magnus (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Both fluid flow and Smart Water EOR process in reservoirs are affected by the reservoir wetting. In order to study the wettability effect of polar organic components present in crude oil, the adsorption of acidic and basic ... -
Smart Water injection to enhance oil recovery in carbonate reservoirs – Acid number and base number adsorption onto chalk
Gaybaliyev, Heydar (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)Water-Based Enhanced Oil recovery (EOR) by injecting "Smart Water" in Carbonate Reservoirs have shown promising results. The success of EOR-process waterflooding by “Smart Water” is dictated by the initial wetting condition ... -
“Smart water” as a wettability modifier in chalk: The effect of salinity and ionic composition
Fathi, Seyed Jafar; Austad, Tor; Strand, Skule (Doctoral thesis; Journal article; Peer reviewed, 2010)Seawater can improve the water wetness of chalk at high temperatures, which improves the oil displacement by spontaneous imbibition of water. It is experimentally verified that the interaction between Ca2+, Mg2+, and SO42− ... -
Water-based enhanced oil recovery (EOR) by “Smart Water”: optimal ionic composition for EOR in carbonates
Fathi, Seyed Jafar; Austad, Tor; Strand, Skule (Journal article; Peer reviewed; Doctoral thesis, 2011)The composition of the injecting brine has a profound effect on the efficiency of water-based enhanced oil recovery (EOR) methods. Recently, we observed that not only is the concentration of the active ions Ca2+, Mg2+, ... -
Wettability alteration in carbonates: the effect of water-soluble carboxylic acids in crude oil
Fathi, Seyed Jafar; Austad, Tor; Strand, Skule; Puntervold, Tina (Journal article; Peer reviewed; Doctoral thesis, 2010)Acidic components in crude oil influence the wetting condition through their effect on electrostatic interactions with the mineral surfaces. In this paper, we have extracted water-soluble acids from a crude oil with a high ... -
Wettability in chalk, effect of initial water saturation on the adsorption of polar oil components
Wakwaya, Abdi (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Experimental study of wettability alteration was aimed at three laboratory designated chalk material, collected from the same reservoir block, at different initial water saturations (0%, 10%, and 40%). Crude oil sample ...
