• A Study of Possible Approaches for Considering Well Abandonment in the Well Design Stage 

      Haukelid, Vlad (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-13)
      There are many fields on Norwegian Continental Shelf (NCS) that approach end of their design life. Based on feasibility studies, life of some fields is prolonged while it is shortened for others. Since early days there ...
    • Life Cycle Well Integrity and Reliability 

      Haaland, Bjarne (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-11)
      This thesis presents a method for reliability based casing design. The method is inspired by the model described by Das et al. (2015) - A model for Well Reliability Analysis throughout the Life of a Well Using Barrier ...
    • P&A of Valhall DP wells 

      Njå, Nils Oskar Berg (Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)
      The original platforms on the Valhall field will have to be decommissioned due to integrity issues. The oldest drilling platform, Valhall DP, has 30 wells that must be P&A in order to remove the platform. This thesis ...
    • ROP optimization and modelling in directional drilling process 

      Kuznetcov, Artem (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-01)
      Rate of penetration (ROP) is one of the most critical parameters affecting virtually all drilling characteristics including technical, operational, economical, safety and other aspects of it. ROP evaluation may provide ...
