Acoustic and elastic least-squares two-way wave equation migration with exact adjoint operator
DownloadSpring 2017
A major problem in exploration seismology entails estimating subsurface structures and properties via linearized inversion. The problem is often called ''least-squares migration" where seismic imaging is posed as an iterative least-squares problem. The iterative solution employs the method of...

Efficient algorithms for least squares wave equation migration and source signature estimation
DownloadFall 2017
Estimating accurate images of the subsurface is one of the end products of seismic data processing. Numerical solutions to the wave equation allow designing linearized forward operators. The adjoint of the linearized forward operator is used to image the interior of the earth. The adjoint...
