    • Analysis of the de-rated Burst and Collapse Resistance of a Locally Worn Tubing by using the Finite Element Method and API models 

      Eriksen, Jan Vidar (Master thesis, 2017-06-15)
      A well integrity survey performed by the Petroleum Safety Authority showed that tubing related problems are a major issue on the Norwegian Continental Shelf. Caliper log runs carried out by ConocoPhillips revealed that the ...

    • Borehole stability on Yme 

      Vikeså, Dan Ole (Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)
      The main object of this thesis it to perform an in-situ stress and borehole stability evaluation of the wells in the Yme field. The Inversion technique was used find the maximum and minimum horizontal stresses. The ...

    • Finite element method simulation and modeling of tubing wear 

      Vu, Therese (Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)
      This thesis presents finite element method (FEM) based on tubing wear simulation studies. Based on wear depth observed from field data, several scenarios were simulated. These are shut-in, production and gas injection. ...

    • Well collapse modeling & Norne & Heidrun well instability sensitivity studies 

      Buan, Irene (Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)
      Well collapse is a typical wellbore instability problem in brittle shale and unconsolidated formations. In this thesis, the thermal, chemical, mechanical, hydraulic, elastic and transient effects on the well collapse ...
