... Multi-sensor streamers have many advantages over traditional hydrophone-only streamers. In particular, they provide a measure of the pressure gradient which allows for data driven broadband de-ghosting. This results in an improved subsurface image and allows the streamer to be towed deeper...

The key procedures incorporate simultaneous inversion of water velocity correction, clock drift, node and source positioning, processing of near-field hydrophone data, multicomponent rotation and noise elimination, and wavefield separation in 3D Radon space...

... and the sea-surface. For the inversion problem to be well-posed in solving for these extra unknowns, additional near-field hydrophone measurements must be made. The advantage over the standard approach is a more accurate treatment of the ghost and no requirement to optimize model parameters. It is also found...

... ABSTRACT Near-field hydrophone (NFH) data from hydrophones attached to a marine source array are commonly recorded for every shot in a seismic survey and are typically used for source signature estimation. There is recent interest in using NFH data to acquire near zero-offset reflection data...

... ABSTRACT We derive marine seismic signatures using twice the usual number of near-field hydrophones, following the proposition of Parkes and Hatton (1986), in which the notional sources and their virtual image are solved for directly. This removes the need to assume a value for the free...
