Chapter 8 – Understanding Sample Data
Enwenode Onajite, in Seismic Data Analysis Techniques in Hydrocarbon Exploration, 2014
During seismic data acquisition, as the acoustic wave (seismic signal) radiates through the subsurface, the amplitude of the seismic signal decreases due to spherical divergence and also higher frequencies within the seismic signal are attenuated due to absorption. By restoring these high frequencies, deconvolution can improve the vertical resolution of the seismic signal by producing a broad bandwidth with high frequencies and relatively compressed wavelet. This chapter of “Seismic Data Analysis Techniques in Hydrocarbon Exploration” explains the concepts of deconvolution and various deconvolution techniques used in the oil industry to improve the frequency content of the data. All concepts are illustrated using seismic data and diagram for easy comprehension and pleasant reading.
