    • Wet Drilled Cuttings Bed Rheology 

      Pedrosa, Camilo; Saasen, Arild; Lund, Bjørnar; Ytrehus, Jan David (Peer reviewed; Journal article, 2021)
      The cuttings transport efficiency of various drilling fluids has been studied in several approaches. This is an important aspect, since hole cleaning is often a bottleneck in well construction. The studies so far have ...

    • Wet-granular rheology to measure cuttings-bed strength 

      Pedrosa, Camilo; Ytrehus, Jan David; Aschl, Timothy; Lund, Bjørnar; Saasen, Arild (Peer reviewed; Journal article, 2021)
      Drilled cuttings-bed formation is a natural process during wellbore drilling operations, although it is not desired. To optimally remove the drilled cuttings out of the wellbore it is important to break the formed beds. ...

    • Whirling dynamics of a drill-string with fluid–structure interaction 

      Volpi, Lucas; Cayeux, Eric; Time, Rune Wiggo (Peer reviewed; Journal article, 2023)
      Fluid–structure interaction models for drill-string vibrations are often of reduced order. However, both the structure and the surrounding fluid are non-linear, which can lead to complex coupled dynamic. In this paper, a ...

    • Zonal Isolation Material for Low-Temperature Shallow-Depth Application: Evaluation of Early Properties Development 

      Agista, Madhan Nur; Khalifeh, Mahmoud; Saasen, Arild; Yogarajah, Elakneswaran (Peer reviewed; Journal article, 2023)
      Shallow-depth cementing presents unique challenges due to its low temperature and low pore pressure characteristic. The curing process of the cementitious material is typically prolonged at low temperatures resulting in a ...
