    • Cuttings Transport in Inclined Sections 

      Kosberg, Birgitte Ruud (Master thesis, 2017)
      Mud rheology is a key parameter in hole cleaning efficiency. Field data suggests that oil-based drilling fluids perform better compared to water based drilling fluids in the field, even with identical rheological properties, ...
    • Effect of Preconditioning and Ageing on Rheological Properties of Model Drilling Fluids 

      Werner, Benjamin; Lund, Bjørnar; Kosberg, Birgitte; Johansen, Espen; Giil, Gunnar Lia; Ytrehus, Jan David (Chapter, 2017)
      Many drilling fluids are thixotropic, meaning that viscosity decreases with time when subjected to shear. Other fluids may show anti-thixotropic (rheopectic) behavior, i.e. viscosity increase with time when subjected to ...
    • Experimental study of the use of tracing particles for interface tracking in primary cementing in an eccentric hele–shaw cell 

      Taheri, Amir; Ytrehus, Jan David; Lund, Bjørnar; Torsæter, Malin (Peer reviewed; Journal article, 2021)
      We present the results of the displacement flows of different Newtonian and Herschel–Bulkley non-Newtonian fluids in a new-developed eccentric Hele–Shaw cell with dynamic similarly to real field wellbore annulus during ...
    • Flow properties of water-based drilling fluids 

      Kristensen, Aleksander (Master thesis, 2013)
      The objective of this master thesis was to investigate the flow properties of water based drilling fluids, utilizing measurements in both the micro and macro scale. The research was performed on two realistic drilling ...
    • 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 performance comparison of oil-based and water-based drilling fluids 

      Sayindla, Sneha; Lund, Bjørnar; Ytrehus, Jan David; Saasen, Arild (Journal article, 2017)
      Cuttings transport is a topic of great interest in the oil and gas drilling industry. Insufficient cuttings transport leads to several expensive problems. Knowledge and selection of the drilling fluids is one of the important ...
    • Properties of Dense Barite Sediments from Water-Based Drilling Fluids Oscillatory Viscosity Measurements of Wet Barite Powder 

      Werner, Benjamin; Pedrosa, Camilo; Skorpa, Ragnhild; Ytrehus, Jan David; Vrålstad, Torbjørn; Saasen, Arild (Journal article; Peer reviewed, 2021)
    • Use of concentric hele-shaw cell for the study of displacement flow and interface tracking in primary cementing 

      Taheri, Amir; Ytrehus, Jan David; Lund, Bjørnar; Torsæter, Malin (Peer reviewed; Journal article, 2021)
      We present our new designed concentric Hele-Shaw cell geometry with dynamic similarity to a real field wellbore annulus during primary cementing, and then, the results of displacement flow of Newtonian and yield-stress ...
    • Use of Tracer Particles for Tracking Fluid Interfaces in Primary Cementing 

      Taheri, Amir; Ytrehus, Jan David; Taghipour, Ali; Lund, Bjørnar; Lavrov, Alexandre; Torsæter, Malin (Chapter, 2019)
      In this study, a new approach for detailed tracking of the interface between well fluid and cement by using particles is investigated. This can improve the quality of annular cementing of CO2 wells and thus the storage ...
    • 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 (Journal article; Peer reviewed, 2021)
