We investigate these techniques with field data from the deep-water Jubarte ocean-bottom cable (OBC) survey offshore Brazil. The VP/VS model along with P-wave velocities determined from NMO analyses or PSDM of the P-wave data provides...

... ABSTRACT PP-wave and PS-wave event registration is an essential element in multicomponent data analysis. In seismic exploration, multi-wave data usually shows big difference in quality, which makes it difficult to obtain stable Vp/Vs ratios, and leads to inaccuracy registration between PP...

... ABSTRACT Mapping post-stack PS-wave data to the PP-wave time domain is a critical step before joint interpretation and inversion. Registration techniques are often constrained by having access to a known ratio. When an accurate ratio is not provided, one can solve the problem of seismic data...

... ABSTRACT As there is a difference of travel path and time between P-wave and converted-wave (C-wave), the kinematics and dynamics characteristic of these seismic waves from the same reflective subsurface layer will also be different. Therefore, event registration in P- and C-waves seismic...

... ABSTRACT Seismic data can experience non-stationary frequency variations caused by attenuation. This problem is encountered when matching multiple data sets, such as in multicomponent image registration, because signals with di?ering frequency content are hard to correlate. In this paper, we...
