Ensemble learning in the estimation of flow types and velocities of individual phases in multiphase flow using non-intrusive accelerometers' and process pressure data
Yan, Ru; Viumdal, Håkon; Fjalestad, Kjetil; Mylvaganam, Saba (Chapter, 2022)Multiphase flows with oil/ gas/ water are common in oil and gas industries. Accurately identifying flow types and estimating flow velocities of the individual phases are crucial for different purposes, such as observing ... -
Optimization of lift gas allocation in a gas lifted oil field as non-linear optimization problem.
Sharma, Roshan; Fjalestad, Kjetil; Glemmestad, Bjørn (Journal article; Peer reviewed, 2012)Proper allocation and distribution of lift gas is necessary for maximizing total oil production from a field with gas lifted oil wells. When the supply of the lift gas is limited, the total available gas should be optimally ... -
Velocity Monitoring of Phases in Oil/Gas/Water Multiphase Flow
Rahman, Abdur (Master thesis, 2023)Machine learning and deep learning techniques have gained significant attention in recent years for enhancing the precision and efficiency of velocity estimation in multiphase flow. This thesis aims to achieve three ...
