Abstract
When a 3D marine seismic survey is being acquired, a large number of factors may give rise to events which can affect data and cause uncertainties. At present ordinary sections give us a single and therefore limited image of our observations. If we move on to a binocular vision, for example, by processing the near and far traces separately, our observations acquire a degree of perspective. Comparison of this perspective with certain attributes provides the means of removing a number of artefacts. We are therefore compelled to develop our own means of detecting, displaying and measuring these causes of uncertainties. Such action will enable us to set in place corrective measures intended to recognize and then control their influence by different methods: removal, appropriate digital processing to take them into account, development of acquisition standards, etc.
