EAGE 2014 saw us do some of our first presentations on DUG Broad: our ghostbuster! The presentations were immensely popular with delegates waiting in the aisles, wanting to know more. DUG Broad is DownUnder GeoSolutions’ physics-based weapon against ghost reflections. Using a unique design window architecture, we account for the variability in receiver depth, source depth, obliquity, sea state, and SNR. An initial modelled signature is optimised to match the observed signature within each design window.
It is critical that the exact location of the notches is known in order to calculate an inverse operator for the accurate correction of the variable phase and amplitude distortion present throughout any given dataset.
So when you want broadband processing you can trust, who you gonna call?
