Paradigm shift in 3D multicomponent seismic imaging in the Arabian Gulf

3D Seismic Survey Design, Second edition

“…This principle is also explained by Barr (1997). Many papers describe techniques for combining the hydrophone and geophone signals to remove the receiver ghost and surface reflections (e.g., Paffenholz and Barr, 1995;Ball and Corrigan, 1996;Soubaras, 1996;Amundsen et al, 2001;Brunellière et al, 2004;Reilly et al, 2008Reilly et al, , 2010. The hydrophone and vertical geophone not only record ghosts and multiples reflected from the water surface differently, but their noise behavior is quite different as well (as seen in Figure 5.52).…”

“…The hydrophone and vertical geophone not only record ghosts and multiples reflected from the water surface differently, but their noise behavior is quite different as well (as seen in Figure 5.52). Reilly et al (2008Reilly et al ( , 2010 take this into account by separate processing of both components for a merge at the last moment. Their papers show considerably improved results over older techniques that combine the two components at an early stage in the processing.…”

Imaging challenges in a producing Mideast carbonate platform environment

“…The "noise field" exhibits different character on hydrophone and geophone data ( Figure 1). The results of the surface-wave noise attenuation for this project were previously published (Reilly et al 2008).…”

Reverberation Attenuation Strategy for an Arabian Gulf 3-D OBC Survey

“…The high level of noise in the data, of which Figure 1 is typical, complicates the de-reverberation process. To reduce the effect of noise on the combination of the two components, we employ a poststack approach (Reilly et al, 2008). We estimate the waterbottom reflection coefficient, R wb , from CMP stacked OBC hydrophone and geophone volumes using Duren's (2003) method.…”
