The course is designed for practicing geoscientists and geoscience students who desire a better understanding of the principles and limitations of both current and emerging technologies involved in subsurface parameter estimation and imaging. The material is designed to help readers better understand how contemporary velocity estimation methods work, and what approximations are involved in obtaining computationally tractable solutions. The evolution of the industry's approaches to building earth models with ray tomography and full waveform inversion is covered, as are some of the emerging possibilities for replacing imaging techniques with direct subsurface parameter inversion methods. The approach will be mostly non-mathematical, concentrating on an intuitive understanding of the principles, demonstrating them via case histories.

Course Outline:
 -Near Surface & Topography
 -Overview of the principles of migration
     -Ray versus wave descriptions
     -Creating gathers for WEM methods & least-squares modification
     -How various algorithms differ, what their limiting assumptions are, etc.
 -Ray-based Tomography
     -Generic update loop: Hybrid gridded tomography
     -Non-parametric picking
 -Wave-based tomography
 -Industry comparisons of tomography & FWI
 -Future directions

Optional topics that may be covered depending on time
 -Seismic response to strong lateral contrasts: e.g. salt
 -Seismic response to strong vertical contrasts: e.g. chalk
