    • Wall Temperature Analyses of Sandwiches Sections Using Infrared Thermography to Evaluate Micro-Annuli size 

      Rosero, Robert (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-15)
      This study mainly focuses on the detection and characterization of micro-annuli at the interface of cement and casing, usually caused by changes in pressure, temperature, or volume change of zonal isolation material. For ...
    • 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 Design With an Environmental Focus 

      Karlsen, Denise (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-08)
      The decisions made during well planning have mainly been focused on safety, cost efficiency and applicability of the design. As the climate have been getting more attention the past years, environment is now high up on the ...
    • 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 ...
