• Hydraulic Behavior in Cased and Open Hole Sections in Highly Deviated Wellbores 

      Ytrehus, Jan David; Lund, Bjørnar; Taghipour, Ali; Kosberg, Birgitte Ruud; Carazza, Luca; Gyland, Knud Richard; Saasen, Arild (Chapter, 2019)
      In this paper we present results from flow loop experiments with an oil-based drilling fluid with micronized barite as weight materials. The use of micronized barite allows using lower viscosity drilling fluid, providing ...
    • Oil-based drilling fluid's cuttings bed removal properties for deviated wellbores 

      Ytrehus, Jan David; Lund, Bjørnar; Taghipour, Ali; Carazza, Luca; Gyland, Knud Richard; Saasen, Arild (Peer reviewed; Journal article, 2021)
      Results from cuttings transport tests in the laboratory using different field-applied oil-based drilling fluids with similar weight and varying viscosities are presented in this paper. The fluids are designed for highly ...
