  • Forming a geological model
    Patent number: 9164188
    Abstract: A method of forming a geological model of a region of the earth includes obtaining seismic data relating to the region, the seismic data including seismic traveltime uncertainty. A seismic velocity model of the region may also be provided and includes velocity uncertainty. Three dimensional positions of a plurality of points of the region can then be determined. The three dimensional positional uncertainties of at least some of the points can be calculated from the traveltime uncertainty and the velocity uncertainty. This can be combined with the positions to form a geological model.
    Type: Grant
    Filed: April 11, 2013
    Date of Patent: October 20, 2015
    Assignee: Statoil Petroleum AS
    Inventors: Bjorn Tornstein Bruun, Erik Nyrnes, Jo Eidsvik

  • Forming a geological model
    Patent number: 8442770
    Abstract: A method of forming a geological model of a region of the earth includes obtaining seismic data relating to the region, the seismic data including seismic traveltime uncertainty. A seismic velocity model of the region may also be provided and includes velocity uncertainty. Ray tracing may be performed on the seismic data using the velocity model to determine the three dimensional positions of a plurality of points of the region. The three dimensional positional uncertainties (7-12) of at least some of the points can be calculated from the traveltime uncertainty, the velocity uncertainty, and uncertainty in the ray propagation direction. This can be combined with the positions determined by the ray tracing to form a geological model.
