Abstract
A system, which may be and/or may include a computer system (1, 100), and method (3) for 910 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.
Claims20
A method for identifying a fault patch from a seismic data volume comprising:
- defining an initial active surface in the seismic data volume;
- identifying one or more active surfaces by minimizing the value of a function for energy;
- tracking back the active surfaces to find a set of control points;
- and
- producing the fault patch formed by the set of control points.
A method for identifying a fault patch from a seismic dataset, the method comprising:
- obtaining a faultiness sections from the seismic dataset;
- constructing an initial surface from a plurality of fault lineaments;
- and
- deriving the fault patch from the faultiness sections and the initial surface.
The method of claim. 8, wherein obtaining the faultiness section comprises extracting said faultiness section from the seismic dataset of a faultiness data type.
A system for identifying a fault patch position from a seismic dataset, the system comprising:
- a seismic data volume;
- a fault identification module to receive a selection of multiple fault curves from the seismic data volume;
- and
- a processor adapted to execute the fault identification module to identify one or more active surfaces, to track back the active surfaces to find a set of control points, and to produce the fault patch position formed by the set of control points.
