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 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 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 ... -
Waterflooding of carbonate reservoirs : EOR by wettability alteration
Puntervold, Tina (PhD thesis UiS;50, Doctoral thesis, 2008-05-30)Oil production is generally divided into three stages, primary recovery, secondary recovery and tertiary recovery. In primary recovery, which is usually (but not necessarily) the first production stage, the natural energy ... -
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 ...
