6. To understand deconvolution, we need a model of the recorded seismic trace. Now discuss the validity of the following model: The recorded trace can be represented as the convolution of the earth’s impulse response with the seismic wavelet. This wavelet consists of various components, including the source signature and the receiver impulse response. The earth’s impulse response is its response to a spike input. This impulse response consists of primary reflections (the reflectivity series) plus all possible multiples. Ideally, deconvolution should compress the wavelet as well as eliminate all multiples so that only the earth reflectivity series remains behind.
