    • Development of an improved Nanoparticle-modified Water Based Drilling Fluid 

      Stanislaw, Wrobel (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)
      The objective was to improve conventional water based drilling fluid systems by the addition of nanoparticles. Experiments were conducted to evaluate whether addition of nanoparticles to the drilling fluid could improve ...

    • Heave effects on Drill String during connections 

      Cespedes, Marco Antonio Guzman (Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)
      During the make-up and break-out of the connections, the drill string is wedged in the rotary table and the top of the drill string follows the platform heave movement as the bit is off bottom. This oscillation may be ...

    • Hook load measurement correction with non-uniform movement 

      Erzuah, Samuel (Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)
      In the recent years, oil and gas exploration and production are being carried out in extremely harsh and challenging environmental conditions. Hence, accurate prediction of the hook load is essential in order to minimise ...

    • Torque and Drag Friction Model: Implemented Friction Factor Dependency of Temperature 

      Brekke, Alexander (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)
      We investigated the friction factor dependency of temperature. “Friction factor” is a parameter in the calculations of torque and drag. Increased well reach is dependent on accurate torque and drag modeling. We proposed ...
