Adsorption of Polar Oil Components onto Chalk: Impact of Silica content on Initial Wetting
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-07-30)The wetting state of reservoir rocks, particularly naturally fractured chalk, is fundamental in the efficient application of advanced oil recovery methods by injection of water. In the subsurface crude oil/brine/rock system, ... -
Adsorption of silica nanoparticles in chalk and sandstone and it effect of fluid/rock interactions.
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)This study addresses the adsorption of Silica nanoparticles (NPs) and its effect on fluid/rock interactions in chalk and sandstone reservoirs. The first part of this thesis addresses the kinetic adsorption behaviour of ... -
Analysis of the Antibiotic Ampicillin in Activated Sludge: Method Development and Adsorption Studies
(Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-06)The presence of antibiotics in wastewater treatment plants is a concern, both because of potential release to natural water systems, and connected to the spread of antibiotic resistance genes. In this thesis, the focus is ... -
Effect of Various Silica Nanofluids: Reduction of Fines Migrations and Surface Modification of Berea Sandstone
(Journal article; Peer reviewed, 2017-11)Abstract: This work is aimed at addressing surface modification of berea sandstone by silica nanofluids (NFs). Three types of nanofluids were used: silica/deionized water (DIW), silica in DIW with a stabilizer fluid ... -
Investigation of mechanical property of aplite-based geopolymer for plug and abandonment
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Historically and up to date, ordinary Portland cement (OPC) or a slight variation is the most widely used material for permanent Plug & Abandonment operation. However, there are several challenges related to cement usage. ... -
Modelling of gas production from tight shale formations: An innovative approach
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)Shale gas is one of the most rapidly growing forms of natural gas. Unconventional natural gas deposits are difficult to characterize overall, but in general are often lower in resource concentration and more dispersed over ... -
Reservoir wetting in sandstone reservoirs, adsorption of polar basic oil components onto quartz and feldspar minerals.
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)For more than a decade the mechanism behind flooding with low salinity water have been studied and well documented as increased oil recovery method (EOR) in sandstone reservoirs. Recently Austad et. al. proposed a new ... -
Shale Gas Production - Modelling With Non-linear Flow Mechanisms
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Unconventional shale gas reservoirs are well known as a low permeable reservoirs so production study from such reservoirs is very complex. In recent years, by introducing new techniques such as of massive fracture and ... -
Smart Water injection into sandstone reservoirs for EOR - Optimal mineral sample preparation and influence of feldspar minerals
(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 ... -
Stochastic thermodynamic production model for shale gas reservoirs
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Most operating companies use Decline Curve Analysis (DCA) for their production forecast on Shale Gas assets (Mongalvy, Chaput and Agarwal, 2011). DCA method is based in empirical analysis and the theoretical background ... -
Time to failure of electric cables in seawater
(Masteroppgave/UIS-TN-IMBM/2018;, Master thesis, 2018-06-15)In this paper, the standardized insulation resistance test in water for predicting the service life of low-voltage cables is investigated. The basic explanations for determining thermal ageing and estimating the service ... -
