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 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. -
