    • Fundamentals and physical principles for drilled cuttings transport – Cuttings bed sedimentation and erosion 

      Pedrosa, Camilo; Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2021)
      The increasing necessity of challenging wellbore structures and drilling optimization for improved hole cuttings cleaning has been growing along time. As a result, operator companies have been researching and applying ...

    • Hole cleaning and wet-granular rheology of rock cutting beds: Impact of drilling fluid composition 

      Pedrosa, Camilo; Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2022)
      Cuttings-beds formation is an issue that must be considered during all wellbore drilling operations. This problem increases at highly deviated or horizontal wells, where cuttings removal efficiency becomes one of the most ...

    • Measuring filter-cake cohesive strength and flowability 

      Klungtvedt, Karl Ronny; Pedrosa, Camilo; Saasen, Arild (Peer reviewed; Journal article, 2022)
      The filter-cake has a critical role in temporarily reducing the permeability of the wellbore to prevent issues such as lost circulation, formation damage, wellbore collapse and differential sticking. The filter-cake's ...

    • 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. ...
