Real-Time Minimization of Mechanical Specific Energy with Multivariable Extremum Seeking
(Peer reviewed; Journal article, 2021)Drilling more efficiently and with less non-productive time (NPT) is one of the key enablers to reduce field development costs. In this work, we investigate the application of a data-driven optimization method called ... -
The Role of Micro Gas Turbines in Energy Transition
(Peer reviewed; Journal article, 2022)In the progressively rising decentralized energy market, micro gas turbines (MGT) are seen with great potential owing to their low emissions, fuel flexibility, and low maintenance. The current transformation in the landscape ... -
A study of blockage effects at the wind turbine and wind farm scales
(Peer reviewed; Journal article, 2021-09)The paper provides novel insights into the physics behind the wind turbine and wind farm blockages as well as their effects on the energy yield based on the momentum and energy balance. The current work presents blockage ... -
Surface Complexation Modelling of Wettability Alteration during Carbonated Water Flooding
(Peer reviewed; Journal article, 2022)CO2 capture and utilization is an effective tool in reducing greenhouse gas emissions and hence, combating global warming. In the present study, surface complexation modeling (SCM) with the geochemistry solver, PHREEQ-C, ... -
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 ... -
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 ...
