    • Deepwater drilling problems 

      Kolade, Olawale (Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009)
      Several problems encountered in the deepwater makes it very difficult in terms of accessibility for drilling. In this work, the major problems in the deepwater are identified, and discussed from different perspectives. ...

    • Depleted reservoir drilling : a study of the Ula field in the North Sea 

      Jokela, Tommy (Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)
      Ula is an oil field operated by BP in the southern part of the Norwegian North Sea. As the field matures depleted intervals are drilled to access remaining reserves. Drilling in highly mature fields is challenging, both ...

    • Drilling optimization : drill bit performance optimization using DROPS simulator ( Ekofisk/Eldfisk Field) 

      Oteri, Vincent Akpojevwe (Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)
      Two drilled Wells: Well A and Well B were analysed under the following input data; drilling parameter, survey data, lithology data and bit information using DROPS simulator to showcase the bit performance optimization ...

    • Drilling problems in depleted reservoirs 

      Kartevoll, Morten (Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)
      New oil and gas wells are becoming more challenging to drill. New technology and better understanding of new and existing reservoirs become available, pushing the envelope of what is technically possible and economically ...

    • Dynamics of multiphase dispersed systems in rotating annulus 

      Shchekotov, Dmitry (Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)
      An investigation of multiphase dispersed system dynamics in rotating annulus is described. The investigation was based on measuring rheological constant (viscosity) of two-phase flowing system. The flow was obtained between ...

    • Effect of core cleaning solvents on wettability restoration and oil recovery by spontaneous imbibition in surface reactive, low permeable limestone reservoir cores 

      Aksulu, Hakan (Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)
      The success of oil recovery, by water flooding, in naturally fractured, low permeable limestone reservoirs strictly depends on imbibition of injected water into the reservoir matrix block. Prerequisite of imbibition process ...
