  • Method of combining directional seismic attributes using a supervised learning approach
    Patent number: 6735526
    Abstract: A method of combining directional seismic attributes using a supervised learning approach which may include extracting seismic information from acquired data in a direction along the spatial direction of a body of interest. The method is applicable both to onshore and offshore exploration and provides a more reliable means of detecting, separating and identifying geological features, for example gas chimneys, faults, layers, and any other type of geological objects with a spatial direction and shape. The method is also suited for the detection of reservoir changes by the use of time lapse seismic techniques.
