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 ... -

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
(Bachelor thesis, 2022)Scale buildup is a common problem in oil and gas producing wells all over the world. It gives difficulties to both the production of oil and gas, as well as well intervention operations. The buildup of scale generates more ... -
The Fundamental Principles and Standard Evaluation for Fluid Loss and Possible Extensions of Test Methodology to Assess Consequences for Formation Damage
(Peer reviewed; Journal article, 2021-04)Industry testing procedures such as ANSI/API 13B-1 describe a method for measuring fluid loss and studying filter-cake formation against a medium of either a filter paper or a porous disc, without giving information about ... -
Fundamentals and physical principles for drilled cuttings transport – Cuttings bed sedimentation and erosion
(Peer reviewed; Journal article, 2021)The increasing necessity of challenging wellbore structures and drilling optimization for improved hole cuttings cleaning has been growing along time. As a result, operator companies have been researching and applying ... -
Further Development and Testing of an Autonomous Drilling Rig and Control Algorithms for Improved Drilling Performance
