    • Well control analysis in conventional and riserless reelwell method 

      Utheim, Marit (Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-10)
      The oil industry is nowadays facing several problems as hydrocarbon reserves are declining and challenging areas are forced to explore. Deepwater drilling is one of these challenging areas as increased target depth results ...

    • Well control and training scenarios 

      Hamarhaug, Marianne (Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)
      Well control is needed during drilling operations to maintain a stable and safe well. Moving towards deeper wells with higher pressures and temperatures makes the operational working window smaller and more complicated ...

    • Well control considerations in Arctic drilling 

      Kjær, Linn Kristin (Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-13)
      As the petroleum industry is in a constant move north for new exploration and production areas, both challenges and opportunities are many. The vast majority of the northern hemisphere are characterized by low temperatures, ...

    • Well control during extended reach drilling - conventional drilling compared to the reelwell drilling method 

      Veisene, Audun Tufte (Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-15)
      Well control is always of great importance during well operations. The main purpose of well control is to keep downhole pressures in the operating window between pore and fracture pressure. In the case of a well control ...

    • Well control procedures and simulations 

      Litlehamar, Harald (Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)
      A brief introduction is given to a range of well control procedures. It was found that many of the procedures rely on a set of simplifying assumptions. This is particularly true in the hand calculations for designing a ...

    • Well design considerations for CO2 injection at Prelude 

      Haugstad, Stig Bjoeran (Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011-06-15)
      The global economy is set to grow four-fold by 2050, promising economic benefits and a higher standard of living for millions. At the same time the global community is uniting in an effort to combat global warming. Achieving ...

    • Well engineering simulation (WellPlanTM) challenges and uncertainties in drilling engineering 

      Vazquez Taboada, José (Student paper, others, 2014-05-20)
      The report work on this laboratory simulation, will be simulated a Drilling Operation to identify the challenges that this operation carries, and how to mitigated them. Nowadays, the high demand by Operators to drill ...

    • 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 acids in crude oil and application of enzyme for wettability alteration 

      Halvorsen, Magnus (Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)
      The objective of the project is defined in two phases. The first phase is to study the effect of oil composition and carboxylic acids in the crude oil on the wetting condition and wettability alteration process using ...

    • 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 ...
