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 ... -
Upscaling The Dissolution Process of CO2 into Formation Brine Using the OPM-flow simulator
(Master thesis, 2024)Som verden forblir sterkt avhengig av fossile brensler som sin primære energikilde, har det oppstått økt bekymring for utslipp av menneskeskapte karbondioksid i atmosfæren. Disse utslippene bidrar betydelig til den pågående ... -
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
(Master thesis, 2023)Det er et stort fokus på digitalisering i den norske olje- og gassindustrien, med et kontinuerlig trykk på utvikling og implementering av nye digitale løsninger for å øke produktiviteten og effektiviteten av operasjoner. ... -
Use of Lithofacies and Ichnofacies in Interpreting the Nise Formation
(Master thesis, 2020)Niseformasjonen ble avsatt på den midt-norske kontinentalsokkelen fra Santon til Campan. Niseformasjonens avsetningsmiljø har lenge vært preget av ulike tolkninger, som har plassert formasjonen fra “åpen sjø” til dypere ... -
The Use of Mathematical Programming to Determine Optimal Production and Drilling Schedule in an Offshore Oil Field, A Case Study From the Barents Sea
(Chapter, 2021)A field with two neighboring reservoirs was discovered in the Barents Sea in 2013 and 2014. After a successful extended well test of an appraisal well in 2018 and initial field planning tasks, a preliminary drilling and ... -
Use of Realistic Geomodels and Synthetic Ultra-Deep Directional Resistivity Inversion in the Pre-job Planning of a Horizontal Oil Production Well
(Master thesis, 2016)The aim of this thesis is to test a workflow to improve subsurface understanding by building and updating realistic geomodels for a horizontal well in the Norwegian Continental Shelf (NCS). The focus is on pre-job planning ... -
Use of remote sensing methodology in assessing landslide susceptibility at the upstream catchment of Tamakoshi 3 hydroelectric project, Nepal
(Master thesis, 2011)Identification and evaluation of potential large scale landslides within the catchment of a hydropower project is vital to secure the dam, reservoir and downstream areas. Digital Elevation Models (DEMs) used in a Geographical ... -
Use of Tracer Particles for Tracking Fluid Interfaces in Primary Cementing
(Chapter, 2019)In this study, a new approach for detailed tracking of the interface between well fluid and cement by using particles is investigated. This can improve the quality of annular cementing of CO2 wells and thus the storage ... -
Use of Underwater Hyperspectral Imagery for geological characterization of the seabed
(Master thesis, 2014)This master s thesis presents an optical mapping method, Hyperspectral Imaging (HI) and its application to marine geological mapping - Underwater Hyperspectral Imaging (UHI). UHI uses similar technology as terrestrial HI ... -
Using Acoustic Emission to monitor sand production
(Master thesis, 2023)Denne oppgaven tar for seg oppgraderinger av sandinjeksjons-systemet i flow-loop systemet, og utviklingen av et Python-program for å analysere kornstørrelser hos sand. Målet er å forbedre ytelsen og påliteligheten til ... -
Using combinatorics to compute fluid routing alternatives in a hydrocarbon production network
(Journal article; Peer reviewed, 2017)Typically, hydrocarbon production networks have several fluid routing alternatives that are applied by opening and closing on–off valves. This usually sends the wells’ fluids through a specific pipeline, pump or compressor, ... -
Using DWT to monitor the borehole condition while tripping to optimize and increase tripping speed and monitoring of EMW while tripping to see any changes in pressure downhole.
(Master thesis, 2022)Drilling operations are the most expensive in oil and gas industry. One of the main contests in drilling is about tripping with considering pressure windows. While tripping in and out, there can be rise or fall in bottom ...
