Polysulphate as Smart Water Additive for Improved Oil Recovery from Carbonate Reservoirs
Algazban, Saja (Master thesis, 2022) -
Polysulphate: A New Enhanced Oil Recovery Additive to Maximize the Oil Recovery From Carbonate Reservoirs at High Temperature
Khan, Md Ashraful Islam; Piñerez Torrijos, Iván Darío; Aldeen, Saja H.; Puntervold, Tina; Strand, Skule (Peer reviewed; Journal article, 2022)Seawater (SW) injection is an enhanced oil recovery (EOR) success in the North Sea carbonate reservoirs due to wettability alteration toward a more water-wet state. This process is triggered by the difference in composition ... -
Production of Smart Water by Acid Flooding in Chalk Cores: Oil Recovery Effects at Intermediate Temperature
Lindanger, Markus (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)Considering that most carbonates are of low water wetness, it is of great interest to inject a brine that can alter the wettability to enhance oil production. Smart Water injection has therefore become the most meaningful ... -
Production of Smart Water by Acid Flooding in Chalk: Temperature Limitation at Slightly Water-Wet Conditions
Andreassen, Erlend (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)Seawater has proven to be an excellent injection fluid in chalk due to its ability to alter the wettability towards more water-wet conditions at high temperatures. This chemically induced wettability alteration improves ... -
Reproducing wettability in sandstone reservoir core material in laboratory core restorations
Aslanidis, PANAGIOTIS; Strand, Skule; Piñerez Torrijos, Iván Darío; Puntervold, Tina (Peer reviewed; Journal article, 2021-09)Replicating initial reservoir wettability conditions in core restoration by core cleaning and fluid restoration in the laboratory is of great importance. There are several core cleaning and restoration protocols used in ... -
Smart Water EOR potential in Brazilian oilfields
Ferreira, Eliane (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)The fact that the petroleum industry still invest a lot of money on different oil recovery techniques indicates that there is an increasing demand for oil that needs to be met. Water flooding is a common secondary oil ... -
Smart Water injection into sandstone reservoirs for EOR - Optimal mineral sample preparation and influence of feldspar minerals
Hetland, Bente (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Smart Water is an injection brine that has been modified and designed for inducing wettability alteration to increase oil recovery in a reservoir. It is an cost effective and environmentally friendly EOR method that can ... -
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 ... -
The Effect of Adsorption of Crude Oil Polar Organic Components on Wettability and EOR Potential by Smart Water on Sandstone Cores
Fazilani, Novia (Master thesis, 2021)Reservoir wettability is widely acknowledged as one of the most influential parameters in oil recovery processes. The complexity of the underlying crude oil brine rock (CoBR) interactions at the interface boundaries acting ... -
The Effect of Injection Rate and Oil Viscosity on Oil Recovery by Waterflooding on Sandstone Cores
Souayeh, Iyad (Master thesis, 2021)With every passing day, the rise for developing and optimizing oil recovery methods and techniques grows, since the global demand for energy is increasing exponentially. Water flooding is still regarded as the most widely ... -
The effect of wettability on waterflooding and relative permeability at quite water-wet conditions in chalk core
Radenkovic, Katarina (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)The effect of performing waterflooding in chalk has been previously tested with a purpose of Enhanced Oil recovery. Regarding oil recovery processes, rock wettability is the key parameter determining transport of fluid ... -
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 ...
