    • A heavy tailed statistical model applied in anti-collision calculations for petroleum wells 

      Gjerde, Tony (Master thesis, 2008)
      Anti-collision calculations are done during the planning of a new petroleum well. These calculations are required in order to control the risk of having a well-collision, which is an unwanted event at any cost. The risk ...

    • Positioning and position error of petroleum wells 

      Gjerde, Tony; Eidsvik, Jo; Nyrnes, Erik; Bruun, Bjørn (Journal article; Peer reviewed, 2011)
      We present a new model for the estimation of positional uncertainty of petroleum wells. The model uses a heavy tailed normal inverse Gaussian distribution for the errors in Earth's magnetic field reference values. These ...
