Fluid flow properties of the Wilhelmøya Subgroup, a potential unconventional CO2 storage unit in central Spitsbergen
(Journal article; Peer reviewed, 2018-11)The Upper Triassic to Middle Jurassic Wilhelmøya Subgroup forms one of the more suitable reservoir units on the Norwegian Arctic archipelago of Svalbard. The target siliciclastic storage unit, which is encountered at approx. ... -
Fluid Migration Characterization of Full-scale Annulus Cement Sections Using Pressure-Pulse-Decay Measurements
(Peer reviewed; Journal article, 2021)Fluid migration behind casings is a well integrity problem that can result in sustained casing pressure, undetected leaks to the environment, and potentially very challenging remediation attempts. Understanding the geometric ... -
Fluid-Rock Interactions for CO2 Geological Storage in Chalk
(Master thesis, 2022)CCS has been recognized as an effective strategy to limit the temperature rise to 1.5 °C by 2050 under the Paris Agreement. As a result, more than 50 CCS pilot or large-scale projects have been commissioned in recent ... -
Fluid-sensitive migration mechanisms predict association between metastasis and high interstitial fluid pressure in pancreatic cancer
(Peer reviewed; Journal article, 2022)A remarkable feature in pancreatic cancer is the propensity to metastasize early, even for small, early stage cancers. We use a computer-based pancreatic model to simulate tumor progression behavior where fluid-sensitive ... -
Footprints of spontaneous fluid redistribution on capillary pressure in porous rock
(Journal article; Peer reviewed, 2017-05)Pore-scale imaging of two-phase flow in porous media shows that pore filling occurs as cooperative events with accompanying spontaneous fluid redistribution in other parts of the pore space. We present a level set method ... -
Formulation Development of Drilling Fluids with DOE Mixture Model Design Technique.
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-09)The aim of this thesis study is to investigate the effect of three components of a formulation of an oil-based drilling fluid, and how the variation of the percentage of each component affects the rheological behavior of ... -
Formulation of New Drilling Fluids and Characterization in HPHT
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)During the well construction process, a properly designed and formulated drilling fluid is vital in order to successfully drill a well. In HPHT wells, both WBM and OBM properties are significantly affected, specially the ... -
Forstå og håndtere utfordringer knyttet til sandkontroll for utvinning av olje
(Bachelor thesis, 2023)In the petroleum industry, sand production is a prominent technical and economic challenge that may lead to severe implications such as well abandonment and casing erosion. This challenge is particularly pronounced in ... -
Friction coefficcient in wells with black sticky stuff and scale
