Surveying in three dimensions ([[:File:3D Seismic.jpeg|Figure 3]]), registers the sources and receptors ubicates across perpendicular lines in each interest area, which results in a seismic data volume, with bigger density than r2-D seismic, and provides better ubication of the structures. This method generates seismic cubes according to the depth and length of the seismic line and the width of the hydrophones arrangement.

Consist in the repetition of a 3D seismic survey in exactly the same original area, after a determinated time. In consequence, the time function is added to a 3d cube.

4-D seismic consists of the repetition of a 3-D seismic survey in exactly the same original area, after a determined time. In consequence, the time function is added to a 3-D cube. Once that the seismic shows successful results, it is necessary bring an ocean bed survey to look at topography, in an area of 30 km², having as objective establish the substrate conditions for the anchorage or support of the perforation unit. This is realized by bathymetry and cursory seismic. There must also be a wind, current, and wave study.
