# 2D/3D time-stepping for imaging and inversion

 Title 2D/{3D} time-stepping for imaging and inversion Publication Type SINBAD Presentation Authors Xiang Li, Felix J. Herrmann Publisher SINBAD Year of Publication 2014 Abstract In this talk, we present a SLIM version of 2D/3D time-stepping modeling kernel for inversion and imaging. One key aspect of this framework is that the implementation follows some mathematic principles, such as linear operator test. Aside from obeying mathematic principles, we also developed a strategy that allows us to compute the gradient of conventional FWI objective or RTM imaging without storing extra wavefield. We also show some applications of this framework on the Chevron 2014 benchmark elastic synthetic data set.
