A system, which may be and/or may include a computer system (1, 100), and method (3) for identifying a fault patch position from a seismic data volume (103). The system and method may include defining an initial active surface (310) in the seismic data volume (103); identifying (914) one or more active surfaces by minimizing the value of a function for energy; tracking back (916) the active surfaces to find a set of control points; and producing (918) the fault patch position formed by the set of control points.
