ABSTRACT:
A method of rapidly generating horizon maps from a three dimensional volume of seismic traces is disclosed. During batch processing of the digital data representing trace wavelets, "1"'s or "0"'s are determined for each seismic trace of the volume. A "1" at a depth of a trace indicates that a horizon exists at that depth and at other depths of "1"'s of adjacent traces which are within a predetermined depth. In a real time mode, an explorationist selects a seed point thereby identifying a "1" on a particular trace at a particular depth. An automatic scanning procedure finds all other "1"'s at depths of adjacent traces. Each found "1" of adjacent traces is redesignated a seed point and the process is continued until no more "1"'s can be found. A horizon map is created from the depths of each found "1". A record is maintained of parent and child bits whereby seed bits are designated as parent bits and each found bit is designated a child bit. Such parent-child information is useful in editing of horizon maps created by the method. Numerical attributes of the wavelets at the depths of the 1 bits are stored as a function of the depths of the bits, thereby reducing required storage space.
