    • Understanding Leakage Rates in Permanently Abandoned Wells by Studying Natural Hydrocarbon Seepages 

      Tveit, Mari Røstvig (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)
      Permanent plug and abandonment (PP&A) of wells is steadily becoming more important on the Norwegian Continental Shelf (NCS), as a large number of fields are approaching end of their productive life. Combining operational, ...
    • Understanding steady shear flow viscometric functions of IOR polymers 

      Lozhkina, Anastasiia (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)
      Nowadays, oil still remains the main source of energy. And every day the demand on oil is growing and growing. New task arises in front of the people: how to extract more oil from the reservoir? Here comes the Improved ...
    • Water flooding of Eldfisk reservoir cores 

      Cherif, Yosra (Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)
      Enhanced Oil Recovery (EOR) and the effect of the aqueous chemistry on the mechanical strength of chalk have been extensively studied over the years. This is simply because the stability of the reservoir system is affected ...
    • Water Injection in Wisting - importance of barrier management 

      Monsen, Stina Lima (Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-07)
      A preselected Wisting well injector design has been used as a basis for this study. Because of the challenges following an ultra shallow reservoir and an almost negligible stress contrast between the reservoir and cap rock, ...
    • Well Barrier Restoration Across Dual Cemented Liners 

      Skoge, Charlotte (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)
      In the past years there has been an increased focus on decommissioning of wells in the NCS. Decommissioning of wells introduces significant investments with no financial returns and has for those reasons historically had ...
    • Well Modelling of H2S Production on a Field in the North Sea 

      Mburu, Andrew (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)
      Hydrogen sulphide production can prove to be a very costly affair for exploration and production companies. Failure to implement efficient H2S control and mediation strategies can lead to a decrease in production assets, ...
    • Wellbore Collapse Failure Criteria and Drilling Optimization 

      Tranggono, Hadi (Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)
      Design and planning in drilling a well are a key for successful before to execute drilling operation. A good understanding of wellbore stability, design mud, casing, cementing, BHA & drillstring, drilling bit, hole cleaning ...
