A method of estimating thickness of a geological layer includes selecting seismic reflection field data from a subsurface depth interval of interest; providing a plurality of geological models having different layer thicknesses and providing respective model responses from the plurality of geological models; comparing a frequency spectrum of the seismic reflection field data with each of the frequency spectra of the model responses to derive comparison data associated with the different layer thicknesses of the models; and deriving from the comparison data a model layer thickness that is indicative of the thickness of the geological layer.
