Summary:
In seismic prospecting, the first-break travelling time has been widely used. As the seismic industry moves toward denser source and receiver coverage, high-density data which leads to a dramatic increase in fold number, the workload of first-break picking is getting larger and larger. Many techniques has been applied in first-break picking, many traditional techniques are based on energy ratios. Here we proposed a method based on mathematical morphological top-hat transformation to achieve the first-break picking. Then we use synthetic and field examples to shown the performance of this method. The performance prove this method is viable.
