Enhanced oil recovery from Sandstones and Carbonates with “Smart Water”
(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, ... -
Enhanced oil recovery in limestone. Chemical effects of seawater injection on the rock surface at different temperatures
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)The fluid location, flow and distribution in a reservoir rock are to a large extent governed by the wetting condition of the rock. These factors influence oil and gas production, water flood recovery and the performance ... -
EOR in chalk: Optimized oil recovery with modified seawater
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The effect of using seawater or modified seawater as a wettability modifier in chalk has been previously investigated at higher temperatures. This work has shown that “smart water” improves the oil recovery due to ... -
Evaluating Flowing Conditions of Faults and Fractures from Well Testing and Interpretation: A Study Based on Reservoir Simulation
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)The scope of the thesis was inspired by the studies of CO2 storage in saline aquifers containing faults conducted at IRIS within the ENOS project1. In storage site evaluations, assessing and preventing leakage from the ... -
Evaluating provenance techniques in the hydrocarbon industry: Compositional quantification of modern sands from known tectonic settings as analog for the correlation of hydrocarbon bearing rocks in ancient geological settings.
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Major and trace element analyses show different compositions between the sediments of the Karmøy southeast shoreline and the sediments of northern Randaberg. Also supported form petrographic analyses, the Karmøy samples ... -
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 a method of placing cross-sectional barriers during permanent plugging of wells
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)When oil and gas wells reach the end of their production life, they need to be permanently plugged and abandoned. The requirements for a permanent barrier state that it must cover the entire cross-section of the wellbore, ... -
Evaluation of Alkaline Sodium Silicate Gel for Reservoir In-Depth Profile Modifications to Enhance Water Sweep Efficiency in Sandstone Reservoirs
(PhD thesis UiS;221, Doctoral thesis, 2014-03)Alkaline sodium silicate (Na-silicate) is addressed to be applied for in-depth water conformance control in sandstone reservoirs containing high permeability layers. The main factors affecting the gel time, strength ... -
Evaluation of artificial lift methods on the Gyda field
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009)Since a production peak in 1995 the oil production on the Gyda field has decreased. Water cut is increasing and reservoir pressure is decreasing. This thesis is a study of the artificial lift methods being evaluated to ... -
Evaluation of Cellulose Nanocrystals as a Green "Smart Water" Additive in Enhanced Oil Recovery from Sandstone Reservoirs
(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 ... -
