    • Well P&A Tubing Compaction Method Evaluation and Modelling 

      Assaf, Osama (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-07-13)
      The number of aged fields in the North Sea is increasing, and in few years, and there will be a significant increase in number of wells that need to be permanently plugged and due to low oil prices and other reasons, there ...

    • Well stability in shale formations 

      Tariq, Abdullah (Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)
      Well instability in shale formations has been a very major problem due to physiochemical interactions between drilling fluid and formation. In this thesis, chemical, thermal and diffusion effects on the well collapse ...

    • 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. ...

    • Wellhead Fatigue Analysis : Surface casing cement boundary condition for subsea wellhead fatigue analytical models 

      Reinås, Lorents (;163, Doctoral thesis, 2012-05-31)
      Material fatigue is a failure mode that has been known to researchers and engineers since the 19th century. Catastrophic accidents have happened due to fatigue failures of structures, machinery and transport vehicles. ...

    • Wettability alteration in carbonates: the effect of water-soluble carboxylic acids in crude oil 

      Fathi, Seyed Jafar; Austad, Tor; Strand, Skule; Puntervold, Tina (Journal article; Peer reviewed; Doctoral thesis, 2010)
      Acidic components in crude oil influence the wetting condition through their effect on electrostatic interactions with the mineral surfaces. In this paper, we have extracted water-soluble acids from a crude oil with a high ...

    • Wettability in chalk, effect of initial water saturation on the adsorption of polar oil components 

      Wakwaya, Abdi (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)
      Experimental study of wettability alteration was aimed at three laboratory designated chalk material, collected from the same reservoir block, at different initial water saturations (0%, 10%, and 40%). Crude oil sample ...
