Evaluation of experimental methods to determine wettability
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Two methods to evaluate the wettability of carbonates have been investigated: Aqueous cationic surfactant solutions contact angles on oil-wet calcite crystals, and imbibition time of surfactant drops into oil-wet ... -
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. ... -
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 ... -
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 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 Wood' theory within buckling
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010) -
Fracture propagation modeling
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)In oil and gas production, hydraulic fracturing is often performed to increase the productivity of hydrocarbon reservoirs. During drilling operation, when the differential well pressure exceeds the strength of the ... -
Genuine two-phase flow dynamics with a free interface separating gas-liquid mixture from gas
(Journal article; Peer reviewed, 2013)This paper deals with a two-phase compressible gas-liquid model relevant for modeling of gas-kick flow scenarios in oil wells. To make the model more realistic we include a natural pressure-dependent well-formation ... -
Global weak solutions for a gas liquid model with external forces and general pressure law
(Journal article; Peer reviewed, 2011)In this work we show existence of global weak solutions for a two-phase gas-liquid model where the gas phase is represented by a general isothermal pressure law, whereas the liquid is assumed to be incompressible. To make ... -
Hole cleaning and hydraulics
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Cuttings transport and efficient hole cleaning remains a vital challenge when planning and drilling vertical, deviated, high angle and extended reach wells. Optimization of cuttings transport depends on so many factors- ... -
Identification of local environmental, geographical or cultural factors that may influence offshore operations and maintenance processes.
(Masteroppgave/UIS-TN-IØRP/2014;, Master thesis, 2014-06-16)The oil and gas industry has evolved for centuries. The development of the society and the rapid grow of global economy require energy as a driven force for the engine of global economy plays a significant role in providing ... -
Importance of fault communication for predicted Snorre performance
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009) -
Mathematical modeling of water-rock chemistry during water injection and its impact on the composition and porosity of chalk
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010) -
The mechanical behavior of chalk under laboratory conditions simulating reservoir operations
(PhD thesis UiS;, Doctoral thesis, 2010-06-08)This work has been carried out with the chalk mechanics research society at the University of Stavanger. The PhD thesis is thus a continuation to the long line of experimental chalk research carried out honoring the ... -
Numerical simulation of surfactant flooding in mixed wet reservoirs
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Surfactants have been considered for enhanced oil recovery either by reduction of oil–water interfacial tension (IFT) or through wettability alteration. This study reveals the effect that reduced interfacial tension has ... -
Particle settling in non-Newtonian drilling fluids
(PhD thesis UiS;80, Doctoral thesis, 2009-12-14)Particle settling is relevant for several aspects of drilling and completion operations, and is directly related to safety and operational efficiency. The primary function of particles added to drilling fluids is to ... -
Real time production monitoring with prediction and validation
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009)This Master of Science studies Optimum Online’s real time estimated production at the Ekofisk Field. Information from offshore process sensors are used to validate the individual well estimates and to detect any deviation ... -
Rheological characterization of borate crosslinked fluids using oscillatory measurements
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Fracturing fluid has a very important role in hydraulic fracturing treatment. Viscosity of hydraulic fracturing fluid affects transporting, suspending, and deposition of proppant, as well as flow back after treatment. ... -
