  • Shearwater’s SHarp processing technology comprises a suite of advanced broadband modules that reveal the important sub-surface information at enhanced resolution.

    Data bandwidth is extended and acquisition effects, including bubble energy, source directionality and interference from sea-surface reflections, are removed using the latest algorithms for source signature estimation, de-signature and de-ghosting, and which may be applied to legacy, conventional or broadband-acquired data. 

    Directional signature estimation is carried out via inversion of near-field hydrophone data and utilizes an accurate representation of the physics of propagation within the vicinity of the array using measured geometry and incorporating complexities of bubble motion and source ghost formation. De-ghosting at the receiver-side utilizes a sophisticated inversion algorithm that can handle an arbitrary cable profile (flat, curved, linearly slanted) and which estimates and continually corrects for uncertainties that arise due to rough sea-surface profile and deviations in streamer depth. Derivation and application of precision de-signature and de-ghosting operators on a shot-by-shot basis yields data of the highest clarity and with the widest possible bandwidth. 

The SHarp broadband tool-box includes:

Far field signature estimation from near field hydrophones

Directional source de-signature and de-ghosting

Directional de-bubble for accurate low frequency amplitude and phase

Directional receiver de-ghosting

Receiver de-ghosting in calm and rough sea states

De-ghosting for flat, linear slant or curved cables

Dual sensor combination
