Abstract
Summary
Traveltime picking is an important step in seismic data processing and it plays an important role in tomographic imaging. In this paper, we discuss an iterative optimization strategy for automatic traveltime picking based on instantaneous traveltime. By introducing a filter operator, the iterative method can pick up the traveltime automatically and accurately. Testing this approach on field seismic data reveals its properties and shows it can accurately do the automatic first-breaks and reflections picking.
