Abstract
A technique includes receiving sensor data; sorting the data into a gather representation that corresponds to a plurality of shots of an energy source; and determining a signal cone based at least in part on at least one characteristic of the gather representation. The technique includes processing the sensor data in a processor-based machine to attenuate noise to generate data representing a signal based at least in part on the determined signal cone and the gather representation.
Claims16
A method comprising:
- receiving sensor data;
- sorting the sensor data into a gather representation that corresponds to a plurality of shots of an energy source;
- determining a signal cone based at least in part on an additional travel path between traces for different shots of the plurality of shots by the energy source;
- and
- processing the sensor data in a processor-based machine to attenuate noise to generate data representing a signal based at least in part on the determined signal cone and the gather representation.
An article comprising a non-transitory computer readable storage medium to store instructions that when executed by a computer cause the computer to:
- receive sensor data;
- sort the sensor data into a gather representation corresponding to a plurality of shots of an energy source;
- determine a signal cone based at least in part on an additional travel path between traces for different shots of the plurality of shots by the energy source;
- and
- attenuate noise to generate data representing a signal based at least in part on the determined signal cone and the gather representation.
A system comprising:
- an interface to receive sensor data;
- and
- a processor adapted to:
- sort the sensor data into a gather representation corresponding to a plurality of shots by an energy source;
- determine a signal cone based at least in part on at least one characteristic of the gather representation;
- attenuate noise to generate data representing a signal based at least in part on the determined signal cone and the gather representation;
- construct a model of the noise based on the gather representation corresponding to the plurality of shots by the energy source;
- and
- use the model to attenuate the noise in another gather representation.
