An agenda for the future of Arctic snow research: the view from Svalbard
(Journal article; Peer reviewed, 2023)The Arctic region is warming at over twice the mean rate of the Northern Hemisphere and nearly four times faster than the globe since 1979. The local rate of warming is even higher in the European archipelago of Svalbard. ... -
Iterative Ensemble Smoothers for Data Assimilation in Coupled Nonlinear Multiscale Models
(Journal article; Peer reviewed, 2024)This paper identifies and explains particular differences and properties of adjoint-free iterative ensemble methods initially developed for parameter estimation in petroleum models. The aim is to demonstrate the methods’ ... -
Integrity Experiments for Geological Carbon Storage (GCS) in Depleted Hydrocarbon Reservoirs: Wellbore Components under Cyclic CO2 Injection Conditions
(Journal article; Peer reviewed, 2024)Integrity of wellbores and near wellbore processes are crucial issues in geological carbon storage (GCS) projects as they both define the confinement and injectivity of CO2. For the proper confinement of CO2, any flow of ... -
Quantum maximum power point tracking (QMPPT) for optimal solar energy extraction
(Journal article; Peer reviewed, 2024)Solar energy is key to achieving a more environmentally responsible future. One way to exploit it is to use semiconductor technology through solar panels to generate clean, sustainable, and controllable energy. However, ... -
Robust Optimization Using the Mean Model with Bias Correction
(Journal article; Peer reviewed, 2024)Optimization of the expected outcome for subsurface reservoir management when the properties of the subsurface model are uncertain can be costly, especially when the outcomes are predicted using a numerical reservoir flow ... -
Using the Quemada rheology model for drilling fluids - practical considerations
(Journal article; Peer reviewed, 2024)A mathematical description of the Quemada rheological model is given, focusing on realistic drilling fluids. The purpose of the work described is to derive results that are required for robust, accurate, and efficient ... -
Metaheuristic algorithms and their applications in wireless sensor networks: review, open issues, and challenges
(Journal article; Peer reviewed, 2024)Metaheuristic algorithms have wide applicability, particularly in wireless sensor networks (WSNs), due to their superior skill in solving and optimizing many issues in different domains. However, WSNs suffer from several ... -
Autonomous UAV Exploration and Mapping in Uncharted Terrain Through Boundary-Driven Strategy
(Journal article; Peer reviewed, 2024)Unmanned Aerial Vehicles (UAVs) play a crucial role in exploring unpredictable terrains, such as accident sites and search zones. These robots require autonomous navigation and precise path planning to operate safely and ... -
Feature extraction and pattern recognition in time-lapse pressure transient responses
(Journal article; Peer reviewed, 2024)Monitoring of modern wells equipped with permanent downhole gauges and flowmeters provides large datasets of pressure, temperature and flowrate measurements. On a limited scale, selected events from these datasets are ... -
Overview of how the Calculation of Dynamic Temperature of Drilling Fluids is Closely Linked with Rheology
(Journal article; Peer reviewed, 2024)Based on many years of work with the calculation of dynamic temperature of drilling fluids during operations, a pedagogic overview of how the calculation of heat transfer and temperature is closely linked with fluid flow ... -
Operational Strategies of Two-Spool Micro Gas Turbine With Alternative Fuels: A Performance Assessment
(Peer reviewed; Journal article, 2024)Micro gas turbines (mGT) have not yet succeeded in conquering the small-scale combined heat and power (CHP) market. One reason is that their electrical efficiency is not high enough to maintain a cost-effective operation. ... -
Insights into the effects of anthropogenic activities on oil reservoir microbiome and metabolic potential
(Peer reviewed; Journal article, 2023)Microbial communities have long been observed in oil reservoirs, where the subsurface conditions are major drivers shaping their structure and functions. Furthermore, anthropogenic activities such as water flooding during ... -
Calculating Bayesian model evidence for porous-media flow using a multilevel estimator
(Peer reviewed; Journal article, 2024)We consider calculation of the Bayesian model evidence, which is an essential component in realistic uncertainty quantification. The main motivation is large-scale porous-media-flow problems, where plain Monte-Carlo (MC) ... -
