Geophysical challenges & opportunities of the deep water Angolan offshore

A Review of Seismic-While-Drilling (SWD) Techniques: A Journey From 1986 to 2005

“…These sands were deposited in a series of sinuous channels in deep water, as large amounts of sediment flowed into the Angolan margin from the African craton. 35.37 Modern 3D surface seismic techniques often can help define simple Tertiary channels 36 (Fig.35). However, geoscientists' ability to define a reservoir using seismic imaging is diminished as channel systems become more complex.…”
