Abstract
Seismic data from the Niger Delta is used to test processing sequences involved in
prestack and poststack amplitude and frequency analysis of marine seismic data. Water
bottom reverberations are found to present a formidable challenge in poststack frequency
and amplitude analysis. However, reflectors with anomalously high amplitudes show low
frequency content both in deconvolved poststack data and in the near offsets of prestack
data with no deconvolution, which agrees with results in the literature. Lack of detailed
knowledge of the lithology prevents investigation of the physical nature of the amplitude
and frequency variations.
