Staggered marine acquisition design for complex imaging.

摘要

We present a new staggered acquisition geometry aimed at providing improvements to complex imaging of the subsurface, such as subsalt in the Gulf of Mexico. The proposed design is a linear acquisition geometry that improves the offset and azimuth distribution compared to pre-existing wide azimuth acquisition techniques and generates extra-long offsets of up to 18 km. It also includes a broadband solution, by towing streamers with variable depth shape, to provide significant imaging resolution uplift.
