• Application of 3-D Analytical Model for Wellbore Friction Calculation in Actual wells 

      Ismayilov, Orkhan (Master thesis, 2012)
      With the increasing number of drilled ultra-extended reach wells and complex geometry wells, the drilling limitation caused by excessive torque and drag forces must be further investigated. The wellbore friction being a ...
    • Dual gradient drilling simulations 

      Sigurjonsson, Kjartan Örn (Master thesis, 2012)
      The system studied in this thesis is called the Low Rise Return system and uses a partly filled marine drilling riser with a variable mud level which is used control the bottom holes pressure.Initially main components of ...
    • EXPERIMENTAL STUDY OF DRILLING MUD RHEOLOGY AND ITS EFFECT ON CUTTINGS TRANSPORT 

      Ezekiel, Ekerette Elijah (Master thesis, 2012)
      To determine the carrying capacity of the drilling fluid, also determine the settling velocities of the drilling cuttlings. To produce the Reynold's number experimentally.
    • Influence of Casing Shoe Depth on Sustained Casing Pressure 

      Eikås, Inger Kamilla (Master thesis, 2012)
      In 2006 the Petroleum Safety Authority Norway (PSA) performed a well integrity survey. The survey indicated that about 20 % of wells on the Norwegian Continental shelf (NCS) may suffer from well integrity issues. Most of ...
    • Model for Kick Tolerance 

      Acosta, Carla (Master thesis, 2012)
      Kick Tolerance is an important factor in the industry, that allows drilling engineers to establish several parameters in the development phase of a well, such as casing depths, open hole lengths, etc. It can also be ...
    • Rheological characterization of Polyanionic Cellulose solutions with application to drilling fluids and cuttings transport modeling 

      Busch, Alexander; Myrseth, Velaug; Khatibi, Milad; Skjetne, Paal; Hovda, Sigve; Johansen, Stein Tore (Journal article; Peer reviewed, 2018)
      In petroleum drilling, aqueous Polyanionic Cellulose solutions (PAC) are often used as a drilling fluid model system in experimental laboratory studies to investigate cuttings transport. Cuttings transport refers to the ...
