Modeling of relative permeabilities including dynamic wettability transition zones
(Peer reviewed; Journal article, 2021)Wettability is a pore-scale property that impacts the relative movement and distribution of fluids in a porous medium. There are reservoir fluids that provoke the surface within pores to undergo a wettability change. This ... -
Monitoring of a reverse cement job in a high-temperature geothermal environment
(Journal article; Peer reviewed, 2021)Cementing operations in wellbores, especially for long casings, are often challenging and prone to deficiencies when not properly planned and executed. While exploring for and exploiting of geothermal resources at temperatures ... -
Monolithic and splitting solution schemes for fully coupled quasi-static thermo-poroelasticity with nonlinear convective transport
(Peer reviewed; Journal article, 2020)This paper concerns monolithic and splitting-based iterative procedures for the coupled nonlinear thermo-poroelasticity model problem. The thermo-poroelastic model problem we consider is formulated as a three-field system ... -
Multi-agent informed path planning using the probability hypothesis density
(Peer reviewed; Journal article, 2020)An Informed Path Planning algorithm for multiple agents is presented. It can be used to efficiently utilize available agents when surveying large areas, when total coverage is unattainable. Internally the algorithm has a ... -
Multilevel Assimilation of Inverted Seismic Data With Correction for Multilevel Modeling Error
(Journal article; Peer reviewed, 2021)With large amounts of simultaneous data, like inverted seismic data in reservoir modeling, negative effects of Monte Carlo errors in straightforward ensemble-based data assimilation (DA) are enhanced, typically resulting ... -
Novel iterative ensemble smoothers derived from a class of generalized cost functions
(Peer reviewed; Journal article, 2021)Iterative ensemble smoothers (IES) are among the state-of-the-art approaches to solving history matching problems. From an optimization-theoretic point of view, these algorithms can be derived by solving certain stochastic ... -
A numerical study of flow field and particle deposition in nasal channels with deviant geometry
(Peer reviewed; Journal article, 2021)Deviant geometry of nasal channels results in significant changes to nasal aerodynamics that alter flow resistance, sensation, and the ability to filter aerosols. The invasive, operative modification of nasal geometry might ... -
An old game, new experience: exploring the effect of players’ personal gameplay history on game experience.
(Journal article; Peer reviewed, 2022)This experimental study explores how game experience differs between players with different gameplay histories within the same game universe. We are interested in how prolonged engagement with a game series affects the ... -
On the Organisation of Translation—An Inter- and Transdisciplinary Approach to Developing Design Options for CO2 Storage Monitoring Systems
(Peer reviewed; Journal article, 2022)Interdisciplinary and transdisciplinary collaboration has become a common practice in technology development projects. Rarely, however, the integration (and translation) of knowledge from different disciplines and different ... -
On the use of criteria based on the SMART acronym to assess quality of performance indicators for safety management in process industries
(Peer reviewed; Journal article, 2021)Management of safety, and barriers in particular, includes using information expressing performance, i.e. use of safety performance indicators. For this information to be useful, the indicators should demonstrate adequate ... -
On the use of the vision zero principle and the ALARP principle for production loss in the oil and gas industry
(Peer reviewed; Journal article, 2019)In the oil and gas industry, there is a strong focus on reducing production loss, and in the last decade the industry has adopted Vision Zero as a governing principle, to meet this goal. A previous paper has concluded that, ... -
An Overall Furnace Model for the Silicomanganese Process
(Journal article; Peer reviewed, 2021)Controlling and optimizing smelting processes in submerged-arc furnaces are complicated by the limited amount of information available regarding the internal conditions. Computer models can help to bridge this knowledge ... -
Overview of the Potential of Energy Harvesting Sources in Electric Vehicles
(Peer reviewed; Journal article, 2023)Energy harvesting, a cutting-edge technology that captures wasted energy from vehicles, constitutes a means to improve the efficiency of electric vehicles. Dissipated energy can be converted into electricity using regenerative ... -
p-Kernel Stein Variational Gradient Descent for Data Assimilation and History Matching
(Journal article; Peer reviewed, 2021)A Bayesian method of inference known as “Stein variational gradient descent” was recently implemented for data assimilation problems, under the heading of “mapping particle filter”. In this manuscript, the algorithm is ... -
Participatory Design of VR Scenarios for Exposure Therapy
(Chapter, 2019)Virtual reality (VR) applications for exposure therapy predominantly use computer-generated imagery to create controlled environments in which users can be exposed to their fears. Creating 3D animations, however, is demanding ... -
Patient use and experience with online access to electronic health records in Norway: Results from an online survey
(Peer reviewed; Journal article, 2020)Background: The electronic health record (EHR) has been fully established in all Norwegian hospitals. Patient-accessible electronic health records (PAEHRs) are available to citizens aged 16 years and older through the ... -
