Abstract

Precise mapping of channel sands within Daman and Mahuva formations along with deeper prospects within trap and below in the Northern part of Mumbai offshore Basin was very difficult with the existing processed dataset. Therefore, to improve the existing data an attempt has been made by re-processing the data from pre-stack stage and subsequent improvement through spectral whitening / balancing on migrated data. Spectral Whitening sometimes called balancing or broadening is a process usually applied to improve the resolution and appearance of seismic data. This case study deals with reprocessing aspects and significant role of spectral whitening in broadening the band width which helped in mapping of channel sands as envisaged.
