    • Annular frictional pressure losses for drilling fluids 

      Saasen, Arild; Ytrehus, Jan David; Lund, Bjørnar (Peer reviewed; Journal article, 2020)
      In the paper it is demonstrated how a Herschel-Bulkley fluid model, where the parameters are selected from relevant shear rate range of the flow and are parametrically independent, can be used for pressure loss calculations. ...

    • Viscosity Models for Drilling Fluids: Herschel-Bulkley Parameters and Their Use 

      Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2020)
      An evaluation is presented of the practical usage of the Herschel-Bulkley viscosity model for drilling fluids. If data from automatic viscosity measurements exist, the parameters should be selected from relevant shear rate ...
