At the junctions of the gas-sand layer and the oil-sand layer in this example, the reflections from the two layers tend to interfere, thereby making them practically indistinguishable. This lack of resolution tends to occur whenever layer boundaries are closer to each other than , where is the dominant wavelength of the illuminating seismic signal (Widess, 1973[1]). Deconvolution often improves results in such cases. It is best to apply deconvolution first and then to determine any desired seismic attributes.
