Sources and receivers have also evolved substantially through this time period; but are the advances in acquisition equipment the main reason for the step change in data quality that we see? We believe that evolution in acquisition geometries and resulting increases in trace density have had a much bigger effect. We have seen step changes in data quality as we move from 2D to 3D, then denser and denser wide azimuth geometries which have recently been augmented with simultaneous source acquisition. So is the detail of the acquisition method the key for success, or is it a simple case of "get as many measurements per km2 as possible"?
