Three-dimensional seismic

seismic data acquired as multiple, closely spaced traverses.  3D seismic data typically provides a more detailed and accurate image of the subsurface than 2D seismic

3D seismic is shot similar to 2D, except the “shotpoints” are much closer together and are laid out on a grid, instead of in a straight line. The geophones that receive the reflected sound waves are also laid out in a grid. These technology is good at showing structural traps, but not ideal for showing stratigraphic traps.

3D seismic imaging provides information almost continuously through the subsurface, in a high density grid of points of data, resulting in much better and precise definition of the subsurface geology. [..]

Acoustic measuring technology which uses multiple vessel-towed long hydrophone streamers. This technique generates a 3D model of the deep seabed and is used to locate and analyse oil and gas reservoir [..]
