Adaptive horizon tracking

A computer executable algorithm adapted to propagate a boundary surface of a seed that is placed within a first region of interest of a visual representation of a 3D seismic data so as to follow a probable contour of a non-continuous data representation of at least part of said first region of interest, wherein said algorithm is executable to:

• (i) generate at least one characteristic parameter for a plurality of candidate events of said 3D seismic data within a predefined gate region located forward of said propagating boundary surface;
• (ii) generate and assign a probability characteristic for said plurality of candidate events based on said at least one characteristic parameter;
• (iii) determine a plurality of events of at least part of at least a second region of interest located substantially parallel to and conformant with at least part of said first region of interest;
• and
• (iv) propagate said boundary surface through said non-continuous data representation utilizing at least one constraint linking said propagating boundary surface and said plurality of events of at least part of said at least one second region of interest.
