Abstract
Seismic data may be imaged using or recognizing substantially only primary reflections. Imaging seismic data may include for example integrating a plurality of seismic data points that have substantially similar arrival directions, for example, to a modeled primary ray. Seismic data points may be imaged that for example substantially meet a set of predetermined conditions, for example, conditions substantially unique to primaries, which may include for example arrival direction and angle of reflection.
Claims25
A method of imaging seismic data, the method comprising:
- accepting seismic data points;
- and
- integrating a plurality of the seismic data points if the seismic data points have substantially similar arrival directions and travel times to that of a corresponding modeled primary ray.
A method of imaging seismic data, the method comprising:
- accepting seismic data;
- and
- imaging seismic data points that substantially meet a set of predetermined conditions, wherein the set of predetermined conditions includes at least arrival direction and angle of reflection.
A system comprising:
- a memory to store data corresponding to seismic data points;
- and
- a processor to accept seismic data points;
- and integrate a plurality of the seismic data points if the data corresponding to the seismic data points include substantially similar arrival directions and travel times to that of a corresponding modeled primary ray.
A system comprising:
- a memory to store seismic data;
- and
- a processor to accept the seismic data;
- and image seismic data points having seismic data that substantially meet a set of predetermined conditions, wherein the set of predetermined conditions includes at least arrival direction and angle of reflection.
