    • Particle scale reservoir mechanics 

      Li, Liming (Doktoravhandlinger ved NTNU, 1503-8181; 116, Doctoral thesis, 2002)
      When a petroleum reservoir is produced, the mechanical state of stress is changing, which leads to alteration of rock mechanical behaviour, of fluid flow, and of geophysical parameters. Numerical schemes have been developed ...
    • The engineering of petroleum streams 

      Hoda, Mohammad Faizul (Doctoral thesis, 2002)
      In a multidisciplinary petroleum industry using a wide variety of engineering software, consistent and easy transfer of quantitative data related to petroleum streams is a major issue. Making it more difficult is the lack ...

      Bhatt, Alpana (Dr. ingeniøravhandling, 0809-103X; 2002:129, Doctoral thesis, 2002)
      In this dissertation we have developed multiple networks systems (multinets or committee machines, CM) for predicting reservoir properties e.g. porosity, permeability, partial fluid saturation and for identifying lithofacies ...
    • Groundwater quality of crystalline bedrock aquifers in Norway 

      Frengstad, Bjørn (Dr. ingeniøravhandling, 0809-103X; 2002:53, Doctoral thesis, 2002)
      In cooperation with the Geological Survey of Norway, the Norwegian Radiation Protection Authority, and local health authorities, 1604 groundwater samples collected from Precambrian and Palaeozoic crystalline bedrock aquifers ...
    • Acoustic emission measurements in petroleum-related rock mechanics 

      Unander, Tor Erling (Doktoravhandlinger ved NTNU, 1503-8181; 77, Doctoral thesis, 2002)
      Acoustic emission activity in rock has usually been studied in crystalline rock, which reflects that rock mechanics has also mostly been occupied with such rocks in relations to seismology, mining and tunneling. On the ...
    • Modeling compositionally-sensitive reservoirs 

      Singh, Kameshwar (Doktoravhandlinger ved NTNU, 1503-8181; 59, Doctoral thesis, 2002)
      This research work provides guidelines for choosing the PVT model (black-oil or EOS compositional) for full-field reservoir simulation of volatile/near-critical oil and gas condensate fluid systems produced by depletion ...
    • Methodological framework and design methodology for developing underwater manipulation systems 

      Solvang, Bjørn (Dr. ingeniøravhandling, 0809-103X; 2003:35, Doctoral thesis, 2003)
      Until recently, underwater manipulation tasks have been conducted by human divers alone or in co-operation with ROVs equipped with one or two manipulator arms. Divers are flexible and can perform a lot of different work ...
