Triaxial behavior of a stabilized and a highly porous oil well cement paste at different saturation and drainage conditions
(Peer reviewed; Journal article, 2022)Well cement is the most common barrier material in wells for geothermal and hydrocarbon production. As cements are exposed to hydrostatic loads and periods of deviatoric loading in wellbore environments, it is important ... -
Tuning the interfacial sites between copper and metal oxides (Zn, Zr, In) for CO2 hydrogenation to methanol
(Peer reviewed; Journal article, 2021)The influence of different metal oxides (ZnO, ZrO2, In2O3) in CO2 hydrogenation to methanol over Cu-based catalysts was studied. The catalysts were characterized using x-ray diffraction (XRD), thermal gravimetric analysis ... -
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 ... -
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 ...
