Interpretation of seismic data

As for interpretation, from the processed seismic data the geological structure and the development of the earth's crust are deduced. On the basis of the seismic reflection horizons a geological layer model is developed. The results of other marine geoscientific exploration methods are also considered.

If there is an extended profile net, from seismic data the area distribution of sediment thickness can be deduced. This example shows the thickness of sediments in front of Argentina.

The validity of the interpretation is checked afterwards through modelling. Since 1970 BGR has measured and evaluated about 322,000 km of seismic profile lines. The results of interpretation furnish information on subjects like resource prognosis, environmental protection and climate development.
