:* 2D Seismic: In two dimensions (Figure 2). The sources and receptors of the induced waves are ubicated in a line, having as result a seismic line that cover the structure that we wish to know. The separation of these lines areuicated according to the objective and detail level.

:* 3D Seismic: In three dimensions (Figure 3). For his register the sources and receptors  ubicates across perpendicular lines each in the interest area, having as result a seismic data volume, with bigger density respect 2D seismic, and provide better ubication of the structures. This method generates seismic cubes according to the deep, the length of the seismic line and the hydrophones arrangement wide.

After a successful result in the exploration instance, it must to proceed to the offshore platforms installation. These platforms consists in large dimensions structures,  that besides extract oil and gas, are used like home for the workers and communication towers. Depending the circumstances, the platform can be fixed at the seafloor, float or be an artificial island. There different kinds of platforms (Figure 4), each one with different especial characteristic according to the deposit and ocean bed kind.
