An Analytical TOOLBOX for the Characterization of Chalks and Other Fine-Grained Rock Types within Enhanced Oil Recovery Research and Its Application—A Guideline
(Peer reviewed; Journal article, 2022-06)Analyses of fine-grained rocks like shales, cherts, and specifically chalk are challenging with regards to spatial resolution. We propose a “toolbox” to understand mineralogical alteration in chalk, especially those induced ... -
Efficient Optimization and Robust Value Quantification of Enhanced Oil Recovery Strategies
(PhD thesis UiS;, Doctoral thesis, 2022-06)With an increasing demand for hydrocarbon reservoir produces such as oil, etc., and difficulties in finding green oil fields, the use of Enhanced Oil Recovery (EOR) methods such as polymer, Smart water, and solvent flooding ... -
EOR by Seawater and “Smart Water” Flooding in High Temperature Sandstone Reservoirs
(PhD theses (TN-lER);508, Doctoral thesis, 2020-04)In the last decades, when the first treated injection water has resulted in incremental oil recovery, the activity to explore this technique has increased. And today, Smart Water flooding or low salinity flooding in sandstone ... -
Flow behavior of thermo-thickening associative polymers in porous media: effects of associative content, salinity, time, velocity, and temperature
(Peer reviewed; Journal article, 2022)Above a critical temperature, thermo-thickening associative polymers (TAPs) have a superior ability to decrease the mobility of the water phase, compared to traditional polymers for enhanced oil recovery. The ability to ... -
Investigation of a new application for cellulose nanocrystals: a study of the enhanced oil recovery potential by use of a green additive
(Journal article; Peer reviewed, 2018-02)Cellulose nanocrystals (CNC) were investigated for use in a potential new application, enhanced oil recovery. Core flooding experiments were performed on outcrop sandstone cores using CNC particles dispersed in low salinity ... -
Mineralogy and geochemistry of reservoir and non-reservoir chalk from the Norwegian continental shelf
(Peer reviewed; Journal article, 2021-05)A first and detailed study of the geochemistry and mineralogy characterizing the North Sea reservoir and non-reservoir chalk is provided in this work. The study is based on 185 cores from exploration and development wells ... -
Production of Smart Water by Acid Flooding in Chalk Cores: Oil Recovery Effects at Intermediate Temperature
(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
(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 ... -
Smart Water EOR potential in Brazilian oilfields
(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 ... -
Synthetic polymers for Enhanced Oil Recovery; Mechanical degradation, and alleviation thereof : Experimental study across scales in pipes, chokes, and porous media of regular HPAM, HPAM-ATBS co-polymers, and TAPs
(PhD thesis UiS;, Doctoral thesis, 2021-06)This thesis and the related work concern synthetic polymers for enhanced oil recovery, their ability to reduce the mobility of the water phase during oil recovery, and their predisposition to mechanically break when subjected ... -
Systematic atomic force microscopy and constraints for the determination of wettability and EOR research
(Masteroppgave/UIS-TN-IER/2020;, Master thesis, 2020-07)A highly attractive strategy within the hydrocarbon industry is improving the percentage of recovery from the reservoirs, called Improved Oil Recovery/Enhanced Oil Recovery (IOR/EOR). The Atomic Force Microscope (AFM) is ...
