      The challenging conditions in the deep water Arctic (>100) demands solutions that still have to be develop in order to successfully operate. In terms of production units the FPSO seems like the most likely solution to ...

    • Challenges related to drilling further north in the Norwegian Arctic 

      Lars, Løkling (Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)
      The world’s energy demands are increasing rapidly and the oil & gas industry is forced to search for new acreages for exploration and production. The Arctic is expected to contain a vast amount of the remaining undiscovered ...

    • Challenges related to magnetics and navigation within directional drilling 

      Kular, Sandeep Singh (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)
      Magnetic distortion of magnetometer readings affects the accuracy and efficiency of the wellbore positioning operations, which in turn degrades the industrial viability of the magnetic measurements while drilling survey ...

    • Challenges with Arctic and harsh environment exploration and production 

      Holien, Bjørn Karlsen (Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-15)
      As the world energy needs rises combined with declining reserves in producing hydrocarbon field’s new areas for exploration is needed. A study performed by the U.S. Geological Survey in 2008 estimated that 22% of the ...

    • Characterization and performance of 70/30 and 90/10 OBM mud systems 

      Khaing, Su Wai Aung (Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)
      Drilling fluid is an essential part of drilling operation. The main functions of the drilling fluid are to transport cutting, to maintain well pressure and cooling formation and drill-bit. The detail knowledge of drilling ...

    • Characterization and performance study of OBM at various oil-water ratios 

      Sharman, Thomas (Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015)
      Drilling fluids are an essential part of the drilling operation. One of the main functions of a properly maintained drilling fluid is to suspend cuttings, as well as weighting materials, in static conditions. Insufficient ...
