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 ... -
Modeling of Safety Functions in Quantitative Risk Analysis
Nguyen, Thien Duy (Master thesis, 2012)Quantitative risk analysis in the offshore industry is mandated by the Norwegian legislation. A literature survey is carried out, related to the current legislation from the Norwegian Petroleum Safety Authority (PSA) and ... -
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 ...
