    • Spectral characteristics of high latitude raw 40MHz cosmic noise signals 

      Hall, Chris (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-07)
      Cosmic noise at 40 MHz is measured at Ny-Ålesund (79◦ N, 12◦ E) using a relative ionospheric opacity meter (“riometer”). A riometer is normally used to determine the degree to which cosmic noise is absorbed by the intervening ionosphere, giving an indication of ionization of the atmosphere at altitudes lower than generally monitored by other instruments. The usual course is to determine a ...

    • Modeling of seismic amplitude anomalies associated with CO2 underground storage 

      Nordahl, Janita Louise (Master thesis; Mastergradsoppgave, 2015-06-01)
      Higher amounts of CO2 in the atmosphere has contributed to finding techniques to mitigate the emissions of CO2. One of those techniques is Carbon Capture and Storage (CCS). CO2 can be stored in subsurface reservoirs over time. Monitoring and modeling of reservoirs is important to avoid leakage and to predict how the CO2 could migrate. Modeling is also useful when the seismic interpreter has problems, ...

This thesis focuses on the possibilities of storing CO2 in a reservoir of Middle Triassic-Middle Jurassic age in The Nordkapp Basin, The Southern Barents ...
    • Evaluation of probability of failure of static equipment in pressurized mud systems on an offshore drilling installation 

      Rød, Bjarte (Master thesis; Mastergradsoppgave, 2015-06-01)
      Degradation of pressurized topside static mud equipment is a very complex process. Inspection is a helpful tool to monitor degradation and helps reduce the number of critical failures. If it is left undetected and unchecked, it can lead to leakage resulting in accidents. To set up an effective inspection program, the concepts of Risk-Based Inspection (RBI) can be utilized. RBI helps to develop an ...
