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 circulation loss study
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-07)Circulation losses could occur during any operation that involves pumping into a well. As of today, it is recognized as one of the most costly drilling problems. In some situation it might ... -
Experimental Design and Setup of Circulation Flow Loop - Using Particle Image Velocimetry
(Master thesis, 2017-07-25)Mud left static in a well over a longer period of time can begin to gel up or form filter cakes along the formation wall and in washout zones, which can be difficult to remove. Therefore, proper mud mobilization and removal ... -
Experimental investigation at heavy light interface mixture of Reelwell ERD
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-13)Due to longer offset and large surface area exposure in a reservoir, extended reach drilling (ERD) is a method which is both cost effective and a well potential during the production phase. However, the present ERD method ... -
Experimental Investigation of Mixing and Separation Mechanisms of Oil-Water System
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)The behaviour of oil-water mixtures/emulsions is of great importance for a variety of industries and sciences. Specially in oil and gas industry, it can be encountered at different stages while drilling, production, storage, ... -
Experimental investigation of polymer flow through water- and oil-wet porous media
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The majority of the research conducted on polymer behavior in porous media is either for single phase flow or water-wet cores. The effect of wettability on polymer behavior in porous media is the main focus of this work. ... -
Experimental investigation of the potential of UCA and NMR for the detection of particle sedimentation in drilling fluids
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Both ultrasound and Nuclear Magnetic Resonance (NMR) have previously been investigated for the potential of monitoring barite sag in drilling fluids. The Ultrasonic Cement Analyzer (UCA) registers the speed of ultrasound ... -
Experimental lost circulation and performance simulation studies of 60/40, 70/30, 80/20 and 90/10 OBMs
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)Lost circulation has been and still is a cost factor for the drilling industry. By using lost circulation material in drilling fluid, it is possible to mitigate unnecessary loss of drilling fluid. This thesis presents ... -
Experimental study of low salinity EOR effects from the Varg field
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The extra oil recovery obtained when flooding a sandstone reservoir with low saline water is called low salinity (LowSal) effect. The term salinity refers to amount (and type) of salt that makes up the ionic composition ... -
Experimental Study on Automatic Evaluation of Drilling Fluid Properties
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)The drilling fluid has several important functions such as transporting cuttings out of the well and being a primary barrier during the drilling operation. When drilling challenging wells in the present and future, factors ... -
