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 ...
