SEISMIC ATTRIBUTES FOR STRUCTURAL ANALYSIS

摘要

Embodiments of methods and systems for analysis of geological structures using seismic attributes are described. In some embodiments, a method includes computing a similarity function using one or more seismic attributes at a location within the geological structure along an I direction and a J direction; computing a total optimal similarity function in at least one plane defined by the I and J directions; computing a minimum possible value of the total similarity function for a defined range of rotations; and calculating a discontinuity measure based at least partially on the minimum possible value of the total similarity function.
