Restoration of annular zonal isolation using localized casing expansion (LCE) technology: Treatment of near-horizontal test sections containing a free-water channel
(Peer reviewed; Journal article, 2021-11)Fluid migration behind casings is a well integrity problem that can result in sustained casing pressure, undetected leaks to the environment, and potentially very difficult remediation attempts. Traditional methods for ... -
A review on geothermal wells: Well integrity issues
(Peer reviewed; Journal article, 2020-12)Geothermal energy is an important potential and a strategic area for developing activities regarding renewable energy and future studies. It involves a great potential and a main role in the worldwide energy sector, ... -
Rheology assessment and barite sag in a typical North Sea oil-based drilling fluid at HPHT conditions
(Peer reviewed; Journal article, 2023)The occurrence of barite sag in drilling fluids has relatively often been the cause for gas kicks in oilwell drilling. The subsequent absorption of gas into drilling fluid could lower the density and reduce the viscosity ... -
A solution for funding the development of technology in oilwell drilling
(Peer reviewed; Journal article, 2020-11)This article proposes a novel methodology to solve an existing gap in benchmark definition by the adoption of statistically defined benchmarks as references to test products or technical procedures. In a win–win partnership, ... -
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 ... -

(Peer reviewed; Journal article, 2020-03)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 ... -
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 ...
