Abstract
Seismic data collected by a group of seismic receivers is received, and properties of coherent noise for plural modes of the coherent noise based on the received seismic data are computed to produce a model of the coherent noise for the plural modes. Using the model, the coherent noise is simulated to generate a synthetic noise.
Claims20
A method executed by a computer, comprising:
- receiving seismic data collected by a group of seismic receivers;
- computing properties of coherent noise for plural modes of the coherent noise, based on the received seismic data, to produce a model of the coherent noise for the plural modes;
- and
- simulating the coherent noise using the model to generate a synthetic noise.
1 more element
An article comprising at least one computer-readable storage medium containing instructions that when executed cause a computer to:
- receive seismic data collected by a group of seismic receivers;
- compute properties of coherent noise for plural modes of the coherent noise, based on the received seismic data, to produce a model of the coherent noise for the plural modes;
- and
- simulate the coherent noise using the model to generate a synthetic noise.
1 more element
A computer comprising:
- a storage to store seismic data, and
- a processor to:
- determine parameters of a model of coherent noise according to the seismic data, wherein the parameters include sets of parameters for plural modes of the coherent noise;
- perform simulation, using the model and the associated sets of parameters for the plural modes, to produce synthetic noise;
- and
- subtract the synthetic noise from seismic data.
