Multi-z horizon auto-tracking

A system comprising:

• a processor;
• and
• a memory having processor-readable instructions stored therein, which, when executed by the processor, cause the processor to perform a plurality of functions, including functions to:
• obtain seed data for each of a plurality of surfaces of a multi-Z horizon within a seismic volume;
• generate a data hull for each surface based on the obtained seed data;
• determine a tracking region within the seismic volume, based on the generated data hull;
• automatically track each surface of the multi-Z horizon through the tracking region;
• determine whether or not one or more of the plurality of surfaces violate at least one geological boundary rule associated with the plurality of surfaces;
• and
• when it is determined that one or more surfaces violate the at least one geological boundary rule, truncate the one or more of surfaces such that each surface of the multi-Z horizon honors the at least one geological boundary rule within the seismic volume.
