    • 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 ...

    • Automated MPD level in the oil and gas industry and development possibility 

      Majeed, Qassim Hameed (Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)
      Automation is introduced to the industrial field long time ago, but still in its first steps in the oil and gas industry. There are many reasons led to this slow of automation in this industry. These reasons related to the ...

    • Automatic MPD & downhole temperature estimation and temperature effect on density 

      Liu, Jieyin (Master thesis, 2015-06-15)
      Hydraulic model is the ‘brain’ of an automated managed pressure drilling (MPD) control system. It requires knowledgeable people to set up and tune before operation starts. Glenn-Ole Kaasa’s simplified dynamic wellbore model ...

    • P&A in Arctic conditons 

      Mehari, Elsa Taeme (Master thesis, 2014-06-30)
      All oil and gas wells will require plugging and abandonment (p&a) at some point in their operating life. Considering the challenging nature of the Arctic weather, its remoteness and lack of infrastructures, and its ice ...

    • Rate of penetration optimization using moving horizon estimation 

      Sui, Dan; Aadnøy, Bernt Sigve (Journal article; Peer reviewed, 2016)
      Increase of drilling safety and reduction of drilling operation costs, especially improvement of drilling efficiency, are two important considerations in the oil and gas industry. The rate of penetration (ROP, alternatively ...

    • Reliability Based Casing Design 

      Eleonu, Ositadinma Tochi (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)
      It is a well-known fact that wells are increasingly becoming extremely expensive and difficult to drill as well as develop due to increasing water depth, temperatures, and pressures. All these result in an increasing load ...

    • Wellbore stability and rock mechanics study on the Ula field 

      Immerstein, Tonje (Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-20)
      In the years to come more challenging drilling conditions will occur when the last reserves need to be collected. More directional drilling will be used and good wellbore conditions will be necessary to make this possible. ...
