    • 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 ...

    • Centralization of casings in wells 

      Erland, Petter Indbjo (Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-03)
      Centralization of casings is very important in order to ensure a high quality well. Poor centralization of casing is often the main reason for bad cement jobs, which forces the operators to perform remedial cementing. This ...
