Abstract

Conventional flat streamer seismic data normally have a narrow frequency bandwidth. However, we can enhance the bandwidth using deghosting technology to compensate for ghost notches during the processing of such data. Premigration deghosting is thereby a key step in broadband processing. In this paper, we demonstrate the effectiveness of broadband processing in enhancing the usable bandwidth of the data by reducing the ghost notches using a case study of conventionally acquired 2D seismic data from offshore Philippines.
