    • Cementing Geothermal Steam Wells 

      Haavik, Inger Lill (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)
      Cementing wells with severe temperatures and/or pressures has become a common matter over the years. Running casing and designing the cement job is very difficult with temperatures above 150°C (300°F) which is a common ...

    • Design of Johan Sverdrup water injectors – unlocking the 9 5/8” liner cement job 

      Holme, Andreas (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-14)
      For the injection wells on Johan Sverdrup, cementing operations concerning the 9 5/8’’ liners are extraordinarily critical. Complications like equipment malfunction, losses, and lost rotation, both during circulation and ...

    • Development and Characterization of Norite-Based Cementitious Binder from an Ilmenite Mine Waste Stream 

      Khalifeh, Mahmoud; Saasen, Arild; Larsen, Helge Bøvik; Hodne, Helge (Journal article; Peer reviewed, 2017-08)
      Norite is a major type of solid waste generated during the production of ilmenite. This study focuses on the usability of norite as a solid precursor of alkali-activated cement. Sensitivity analysis was performed to find ...

    • Evaluation of Downhole Tubing Disposal for Permanent Plug and Abandonment 

      Holsen, Andreas (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)
      A new method called Downhole Tubing Disposal developed by Oilfield Innovations for performing rigless permanent plug and abandonment is presented. Instead of pulling the production tubing, the tubing is weakened with ...

    • An Investigation of Sustained Casing Pressure Occurring on the NCS 

      Rød, Kristian Ottestad (Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-12-15)
      Reports from the Gulf of Mexico (GoM) show that thousands of wells exhibit sustained casing pressure (SCP), however the extent of this phenomena and its driving factors have yet to be studied in detail on the Norwegian ...

    • Materials for optimized P&A performance: Potential utilization of geopolymers 

      Khalifeh, Mahmoud (PhD thesis UiS;292, Doctoral thesis, 2016-05)
      When a well reaches the end of its life-cycle, it must be permanently plugged and abandoned. Plug and abandonment (P&A) can easily contribute with 25% of the total drilling costs of exploration wells offshore Norway. The ...

    • Optimize the HydraArchimedes cement insurance tool 

      Rongve, Vegard (Masteroppgave/UIS-TN-IØRP/2018;, Master thesis, 2018-06)
      The HydraArchimedesTM tool is called a cement insurance tool because of its ability to squeeze cement out through casing perforations by rotating the tool inside a casing, thereby creating a rock-to-rock barrier. It is ...

    • Rheological performance of cementitious materials used in well cementing 

      Hodne, Helge (PhD thesis UiS;, Doctoral thesis, 2007-12-14)

    • Using plasma technology to remove scale from production tubing 

      Mohamad, Saresh (Master thesis, 2016-06)
      With its wide application in areas such as electronics, the car-, machine- and tool-making industries, energy technology, the optics industry, and textile, environmental, and medical technology, plasma technology is ...
