oa Broadband Processing of Conventional Marine Streamer Data from Offshore West Africa

In towed streamer marine seismic acquisition, data is typically recorded over a bandwidth of 2-250Hz. This is represented by a wavelet of finite width with side lobes in the time domain when zero phased. This ideal wavelet is distorted by two major factors: the source and receiver-side ghosts and absorption due to various propagation effects (Q). This paper presents two case studies of a deghosting, broadband processing workflow on conventionally acquired (single sensor, flat streamer) data from offshore West Africa.
