Abstract
A method of processing seismic data wherein seismic data signals having a first part which shows a slow variation in offset and a second part which shows a slow variation in midpoint, is modelled using a model which allows the two parts to be separated. The individual parts may be reconstructed from the model. One of the parts corresponds to offset dependent noise and can be effectively removed from the seismic data.
Claims15
A method of processing a plurality of input seismic data samples having a plurality of midpoints and a plurality of offsets, comprising:
- selecting a sample of each of the input seismic data samples;
- defining at least one modelling function having at least one model parameter and comprising a first part which is substantially independent of the offsets of the input seismic data samples and a second part which is substantially independent of the midpoints of the input seismic data samples;
- and selecting the at least one model parameter of the at least one modelling function such that the at least one modelling function represents a best fit to the selected sample of the input seismic data samples.
