Up- and downgoing borehole wavefield retrieval using single component borehole and reflection data
(Journal article; Peer reviewed, 2018)A standard procedure in processing vertical seismic profile (VSP) data is the separation of up- and downgoing wavefields. We show that these wavefields in boreholes can be retrieved using only single-component data, given ... -
Up-scaling of Polymer Flooding with regards to Geologic Heterogeneities
(Master thesis, 2014)Up-scaling of reservoir model is required to save computational time and costs in the industry. Due to numerical dispersion caused by enlarged grid size and reduced reservoir heterogeneity during up-scaling process, the ... -
Updated in situ rock stresses in Norway based on recent estimations and measurements
(Chapter, 2019)This paper presents the current in situ rock stresses in Norway. Information about the stress state was obtained by estimations from focal mechanism, borehole breakout and drilling-induced fractures, and via overcoring and ... -
Updated Norwegian In Situ Rock Stress Database
(Master thesis, 2018)This thesis presents an updated Norwegian in situ rock stress database and collected in situ rock stress data. In situ rock stresses are the stresses that are present in the ground before any disturbance. Knowledge of in ... -
Upper Jurassic Syn-Riftand Lower CretaceousPost-Rift Exploration Potential
(Master thesis, 2010)The master thesis area is located in the North Viking Graben, in blocks 30/7, 10 and11. The NVG05 3D dataset also covers several UK blocks in quadrant 3. TheNorwegian side has been the main focus since the probability for ... -
Upper paleocene ultramafic igneous rocks offshore mid-Norway: Re-interpretation of the vestbrona formation as a sill complex
(Journal article; Peer reviewed, 2017)Continental breakup between NW Europe and Greenland (~56 Ma) ago was associated with widespread magmatism. Silica undersaturated alkaline porphyritic igneous rocks of a similar age have previously been dredged near the ... -
Upper Paleozoic Carbonate Buildups of the Timan-Pechora Basin, the Sverdrup Basin and the Barents Sea as Potential Reservoirs of the Arctic
(Master thesis, 2014)The main objective of this work was to study the three Arctic Provinces: the Timan-Pechora Basin, the Sverdrup Basin and the Barents Sea, and make a comparison between them with a focus on the Paleozoic sediments and their ... -
Upscaling Elastic Parameters on Complex Geometry Grids
(Master thesis, 2013)Statoil and collaborating partners have recently been able to develop a general upscaling technique that takes into account the complex geology and geometry of rocks. Accordingly, it has now become possible to predict ... -
Upscaling of Finely Layered Media in the Presence of Tilted Transverse Isotropy. Application on Well-Log Data.
(Master thesis, 2014)The primary focus of this project is to analyze the effect of tilt angle on effective medium properties in a tilted transversely isotropic (TTI) medium. A well log has been divided into nine blocks, where eight is vertical ... -
UPSCALING OF WELL LOG DATA FOR A TRANSVERSE ISOTROPIC EFFECTIVE MEDIUM
(Master thesis, 2013)We develop two methods to determine; (1) net to gross and hydrocarbon saturation in a mixture of sand and shale. (2) effective properties versus tilt in sand. Backus (1962) and Schoenberg and Muir (1989) averaging are used ... -
Upscaling polymer flooding using MRST
(Master thesis, 2016)Reservoir simulation models are widely used as a decision making tool in oil and gas industry. Modern technologies allow creating very detailed high-resolution models to represent the properties of a reservoir system as ... -
Use of a Punching Technique with Small Samples to Investigate Temperature Dependent Shale Strength
(Master thesis, 2010)Shale makes up more than 70% of drilled formations, and about 90 % of all wellbore stability problems occur when drilling in shale. Drilling with water based mud in deep waters and high deviation, extended reach drilling ... -
Use of a Punching Technique with Small Samples to Investigate Temperature Dependent Shale Strength
(Master thesis, 2010)A flexible pipe consists of several layers of steel and fluid barriers, where the fluid barriers keep the inside (steel) of the flexible pipe dry. Unfortunately, the most frequently damaged component of the flexible pipe ... -
Use of concentric hele-shaw cell for the study of displacement flow and interface tracking in primary cementing
(Peer reviewed; Journal article, 2021)We present our new designed concentric Hele-Shaw cell geometry with dynamic similarity to a real field wellbore annulus during primary cementing, and then, the results of displacement flow of Newtonian and yield-stress ... -
Use of High Energy Laser for Underground Excavation in Hard Rock
(Master thesis, 2020)Bruk av laser er en ny potensiell metode for driving av undergrunnsanlegg. Når høyenergi laser treffer overflaten til en bergart vil det føre til temperaturøkning i bergarten. Dette vil føre til smelting av bergarten i en ... -
Use of Indentation Tests to Study the Rock Breaking Mechanisms Induced by a TBM Disc Cutter
(Master thesis, 2015)Since the introduction of mechanical tunnel excavation technology, there has been conducted numerous theoretical, empirical and experimental studies to explain the interaction between rock and mechanical cutting tools. ... -
Use of KPI as a strategic tool in the implementation of new digital solutions
