Abstract

The benefits of full azimuth acquisition with sparse planted multicomponent nodes at the sea floor are numerous. Improved reservoir characterization from better imaging can be expected .The nodal positions can be located with very high vector fidelity and can be repeated very accurately. The areal sampling is done by the dense shooting .Nodes are much more practical in the presence of obstacles such as production facilities and regular coverage can be assured. Nodes provides converted waves desirable for gas occluded reservoirs, ,fracture detection and lithology characterization
