• On gray-box modeling for virtual flow metering 

      Hotvedt, Mathilde; Grimstad, Bjarne Andre; Ljungquist, Dag; Imsland, Lars Struen (Journal article; Peer reviewed, 2021)
      A virtual flow meter (VFM) enables continuous prediction of flow rates in petroleum production systems. The predicted flow rates may aid the daily control and optimization of a petroleum asset. Gray-box modeling is an ...
    • When is gray-box modeling advantageous for virtual flow metering? 

      Hotvedt, Mathilde; Grimstad, Bjarne André; Ljungquist, Dag; Imsland, Lars Struen (Peer reviewed; Journal article, 2022)
      Integration of physics and machine learning in virtual flow metering applications is known as gray-box modeling. The combination is believed to enhance multiphase flow rate predictions. However, the superiority of gray-box ...
