  • Method of processing seismic data
    Patent number: 5309406
    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.
