    • NCS Drilling Data Based ROP Modelling and its Application 

      Alsenwar, Malik (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)
      Predicting the ROP (rate of penetration) before drilling is essential to improve the overall drilling efficiency and thereby reduce the non-productive time and costs. For this, good ROP model is required. Several ROP models ...

    • ROP modelling and analysis 

      Husvæg, Morten Adamsen (Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-11)
      A total of six techniques are developed to model ROP for a new well. The techniques attain coefficients or specific values from a close-by already drilled well. Using these and drilling parameters, the proposed method ...

    • Torque & drag analyses of North Sea Wells using new 3D model. 

      Tveitdal, Terje (Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)
      Excessive drill string torque and drag is one of the major limitations of extended-reach and horizontal drilling. The torque and drag models are used in the planning phase and during the drilling of a well, as a tool used ...

    • Upscaling of gas relative permeability during pressure depletion 

      Grepstad, Kristian (Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)
      Pressure depletion of an oil reservoir will result in release of dissolved gas when the bubble point of the oil is reached in the reservoir. This liberated gas will segregate upwards in the reservoir with low mobility until ...
