Unravelling key controls on the rift climax to post-rift fill of marine rift basins: insights from 3D seismic analysis of the Lower Cretaceous of the Hammerfest Basin, SW Barents Sea
(Journal article, 2017-10)In this study, we investigate key factors controlling the rift climax to post-rift marine basin fill. We use two- and three-dimensional seismic data in combination with sedimentological core descriptions from the Hammerfest ... -
Use of a transient model for studying kick migration velocities and build-up pressures in a closed well
(Chapter, 2021)The objective of the paper is to show that using pressure build-up curves for estimating kick migration velocities can be unreliable. This will be demonstrated by using a transient flow model where different flow patterns ... -
Using Artificial Neural Networks to Gather Intelligence on a Fully Operational Heat Pump System in an Existing Building Cluster
(Peer reviewed; Journal article, 2023)The use of heat pumps for heating and cooling of buildings is increasing, offering an efficient and eco-friendly thermal energy supply. However, their complexity and system integration require attention to detail, and minor ... -
Validation study of water weakening research from outcrop chalks performed on Eldfisk reservoir cores
(Peer reviewed; Journal article, 2020-11)Seawater injection for Enhanced Oil Recovery (EOR) purposes can increase the hydrocarbon recovery factor in carbonate reservoirs but are also responsible for weakening their mechanical strength. This study investigates the ... -

Vibration-assisted annular fluid displacement for rig-less well abandonment operations
(Peer reviewed; Journal article, 2022-06)Through-tubing abandonment is the operation where the production tubing is cut or punched and cemented inside the production casing. This can establish a full cross-sectional barrier or isolation in wells where the cement ... -
Viscosity Models for Drilling Fluids: Herschel-Bulkley Parameters and Their Use
(Peer reviewed; Journal article, 2020-10)An evaluation is presented of the practical usage of the Herschel-Bulkley viscosity model for drilling fluids. If data from automatic viscosity measurements exist, the parameters should be selected from relevant shear rate ... -
Wet Drilled Cuttings Bed Rheology
(Peer reviewed; Journal article, 2021)The cuttings transport efficiency of various drilling fluids has been studied in several approaches. This is an important aspect, since hole cleaning is often a bottleneck in well construction. The studies so far have ... -
Wet-granular rheology to measure cuttings-bed strength
(Peer reviewed; Journal article, 2021)Drilled cuttings-bed formation is a natural process during wellbore drilling operations, although it is not desired. To optimally remove the drilled cuttings out of the wellbore it is important to break the formed beds. ... -
Whirling dynamics of a drill-string with fluid–structure interaction
(Peer reviewed; Journal article, 2023)Fluid–structure interaction models for drill-string vibrations are often of reduced order. However, both the structure and the surrounding fluid are non-linear, which can lead to complex coupled dynamic. In this paper, a ... -
Zonal Isolation Material for Low-Temperature Shallow-Depth Application: Evaluation of Early Properties Development
(Peer reviewed; Journal article, 2023)Shallow-depth cementing presents unique challenges due to its low temperature and low pore pressure characteristic. The curing process of the cementitious material is typically prolonged at low temperatures resulting in a ...
