      Vikra, Sigurd Eikemo (Masteroppgave/UIS-TN-IPT/2008;, Master thesis, 2008)
      By using real-time data from INTEQ`s CoPilot Real-Time Drilling Optimalization a search for dependable indications of the degree of the bit wear was done. This would improve decision making procedures for when to pull the ...
    • Calculation of forces acting on a rotary steerable liner drilling system 

      Røsbak, André I. (Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)
      Torque and drag calculations performed on a new liner drilling design indicate that a very high grade drillpipe, up to S-135, is required in order to satisfy the requirements which both axial and torsional loading place ...
    • Casing design evaluation for water injectors at Valhall 

      Norum, Espen (Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)
      The Valhall field is the largest field that BP operates on the Norwegian Continental Shelf, and is one of the most well known high porosity chalk fields in the Southern part of the North Sea. During many years of oil ...
    • Creep behavior and loading rate dependency of chalks 

      Nnaemeka, Uwaezuoke (Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)
      ‘‘Mechanically high porosity chalks behave as frictional materials, but with an end-cap reflecting pore collapse failure, and the mechanical properties of chalk are strongly dependent on the type of fluid in the pores’’ ...
    • The influence of pore pressure on rock-fluid interaction 

      Mba, Chinweike Julius (Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)
