Seismic velocity estimation
What are some challenges in seismic imaging?
The two main approaches to seismic imaging produce models for the underground velocities: the first is a process called time migration, which takes seismic data in time coordinates, and produces images and time-migration velocities, which are an averaged velocity of a particular type. The second, depth migration, takes seismic data in depth coordinates and produces seismic images in depth coordinates.
The inverse problem
Ultimately, we are faced with an inverse problem:
We have done the following:
