Seismic Data Processing

Seismic profiling is the technique of using sound waves to image underground rock strata, either on land or under the sea. It is widely used in oil exploration. Once the raw data has been acquired, Seismic Data Processing is then used to convert it into a meaningful form, such as a 2D picture of the cross-section being imaged, and then to enhance that image for greater clarity. This processing consists of a number of stages: filtering, deconvolution, stacking (summing separate seismic traces from the same depth) and seismic migration (the process of geometrically relocating seismic events in space or time).
