    • Analysing Complex Oil Well Problems through Case-Based Reasoning 

      Abdollahi, Jafar (Doktoravhandlinger ved NTNU, 1503-8181; 2007:225, Doctoral thesis, 2007)
      The history of oil well engineering applications has revealed that the frequent operational problems are still common in oil well practice. Well blowouts, stuck pipes, well leakages are examples of the repeated problems ...

    • Diagnosing Root Causes and Generating Graphical Explanations by Integrating Temporal Causal Reasoning and CBR 

      Nikpour, Hoda; Aamodt, Agnar; Skalle, Pål (Journal article; Peer reviewed, 2017)
      This study proposes a methodology to diagnose the root causes of failures in the domain of oil well drilling. The idea is to combine a Bayesian network, which is generated based on an expert knowledge, with situation-specific ...

    • Downhole failures revealed through ontology engineering 

      Skalle, Pål; Aamodt, Agnar (Peer reviewed; Journal article, 2020)
      Frequency of failures occurring during offshore oil-well drilling do not diminish over time, probably due to increased operational complexity. The volume and frequency of information generated during the drilling process ...
