Evaluation of silicate and polymer systems for disproportionate permeability reduction in oil reservoirs
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)The main objective of this work is to screen and evaluate various commercially existing polymers and silicate systems mixed with crosslinkers and/or activators for their gel-forming capabilities for the water management ... -
Evaluation of strategies for fracture modeling: A case study at Teapot Dome, Wyoming
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)The characterization of fractured reservoirs is complex. Fracture modeling is often based on very limited well data and therefore is subject to high uncertainty. Typically, the standard modeling workflow uses interpolation ... -
Evaluation of the compositional changes during flooding of reactive fluids using scanning electron microscopy, nano-secondary ion mass spectrometry, x-ray diffraction, and whole-rock geochemistry
(Journal article; Peer reviewed, 2015-05)Outcrop chalk of late Campanian age (Gulpen Formation) from Liège (Belgium) was flooded with MgCl2 in a triaxial cell for 516 days under reservoir conditions to understand how the non-equilibrium nature of the fluids altered ... -
Evaluation of the primary cement operation on the production casing in the Ekofisk field and the Eldfisk field
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)The foremost goal of primary cementing is to provide zonal isolation in a well. Cementing of the casing/liner set right above the reservoir on the Ekofisk and Eldfisk fields are associated with a lot of challenges. ... -
Evaluation of the “Command Take-Over Procedure” in automated well control
(Master thesis, 2014-06-13)The growing need for new technology in the pursuit of oil is creating new challenges related to well control. Drilling in HPHT (High Pressure High Temperature) reservoirs, arctic areas, and depleted zones might imply ... -
Evaluation of using Smart Water to enhance oil recovery from Norwegian Continental Shelf sandstone reservoirs.
(Master thesis, 2016-06-09)Recently, the scale of studies on smart water – one of EOR method - has increased. From decades, water flooding is one of the most used methods to increase oil recovery. However, more effective in sandstone reservoirs is ... -
Evaluation of WAG injection at Ekofisk
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)In the North Sea many fields are water flooded. Subsequent to water flooding large amounts of water flood residual oil will be left in reservoirs. The challenge is how to improve the oil recovery. On the Ekofisk field such ... -
Evidence for tectonic control deposition of the Brent Group, northern North Sea
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Detailed examination of well-constrained three-dimensional seismic data introduces the role of tectonics in controlling the nature of syn-rift sequences on the hanging wall of faulted blocks, typical Late Jurassic structural ... -
Evolution of porosity and permeability in chalk as an effect of variations in non-carbonate minerals and testing temperature
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)Pressure decline during oil recovery from chalk reservoirs exhibit increase in effective stress and this in turn leads to reservoir compaction causing seabed subsidence. Although, there is positive impact of compaction on ... -
Evolution of the southern Llanos basin
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The Llanos basin, located in the eastern region of Colombia, South America, is a foreland basin between the Eastern Cordillera (Colombian Andes) and the Guyana Precambrian shield. This Andean foreland basin is the latest ... -
Evolution of wetting index over time in mixed wet Kansas chalk using triaxial cells
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Magnesium chloride effects have been widely studied in short and long-term core flooding experiments through outcrop chalk cores. Three main changes are induced by this reactive brine: ion exchange, dissolution of calcite ... -
Examination of Dynamic Stress and Conductivity in the Eldfisk Chalk Field
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-05-26)This thesis work has been conducted in cooperation with ConocoPhillips Norway and looks at the stress development in the Eldfisk chalk reservoir. High injection pressures due to the relatively low permeabilities of chalk ... -
Experimental and numerical simulation of the recovery of oil and the effect of light oil components on CO2 flooding mechanism using sandstone reservoir.
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-29)Carbon dioxide (CO2) flooding is considered as an efficacious method of EOR. It is a complicated process as it involves phase behavior. In order to master the performance of CO2 flooding, a comprehensive investigation of ... -
Experimental and Theoretical Modelling of CO2 Injectivity : Effect of Fines Migration and Salt Precipitation
(PhD thesis UiS;, Doctoral thesis, 2017-11)Adequate well injectivity is required to inject large volumes of CO2 at acceptable rates through a minimum number of wells. Mineral dissolution and salt precipitation could impair CO2 injectivity and reduce the quality and ... -
