Simulation of Oil Production from Homogenous North Sea Reservoirs with Inflow Control using OLGA/Rocx
Sund, Sveinung Martinius; Iversen, Thomas Berg; Hansen, Magnus S.; Bohlin, Jørgen; Vøllestad, Ole Kristian; Furuvik, Nora Cecilie Ivarsdatter; Halvorsen, Britt (Journal article; Peer reviewed, 2017)Advances in drilling technology have made long, horizontal wells the preferred method to extract oil from reservoirs in the Norwegian Sector. Early water or gas breakthrough is a passive inflow control devices (ICD) are ... -
Simulation of Simplified Model for Reaction Kinetics in Biomass Gasification
Agu, Cornelius Emeka; Thapa, Rajan Kumar; Halvorsen, Britt (Conference object; Peer reviewed, 2015-11-25)Due to complexity in interactions between solid particles and between particles and carrier fluid, modeling of biomass gasification kinetics has been shown to be very challenging. Some commercial packages such as Barracuda ... -
Statistical diagnosis of a gas-solid fluidized bed using Electrical Capacitance Tomography
Rautenbach, Christo; Melaaen, Morten Christian; Halvorsen, Britt (Journal article; Peer reviewed, 2012)Fluidization experiments were performed using several particle size distributions of spherical glass particles, ranging from Geldart B to D. An Electrical Capacitance Tomography (ECT) tomograph was utilised in the present ... -
The influence of the experimental span of Time-resolved X-ray tomography on dynamic parameters in a fluidized bed
Rautenbach, Christo; Melaaen, Morten Christian; Halvorsen, Britt; Mudde, Robert F. (Journal article; Peer reviewed, 2011)Fluidized beds have presented some problems to experimentalists in the past due to their opaque nature [1]. This problem has however been overcome by non-intrusive nor invasive measurement techniques. X-rays or Gamma rays ... -
Velocity and turbulence measurements of oil-water flow in horizontal and slightly inclined pipes using PIV
Kumara, W.A.S.; Halvorsen, Britt; Melaaen, Morten Christian (Chapter; Peer reviewed, 2009)Oil-water flows in horizontal and slightly inclined pipes are investigated using Particle Image Velocimetry (PIV). PIV offers a powerful non-invasive tool to study such flow fields. The experiments are conducted in a 15 m ...
