Converted-Wave Imaging in Anisotropic Media – Part I – Theory and Methods

A02 CONVERTED-WAVE IMAGING IN ANISOTROPIC MEDIA – PART I: THEORY AND METHODS XIANG-YANG LI 1 HENGCHANG DAI 1 FABIO MANCINI 2 Abstract 1 We review and present the recent developments in converted-wave (C-wave) processing for vertical transverse isotropy (VTI) in two parts. Part I covers the basic theory and methods addressing issues such as how many parameters are required to perform C-wave anisotropic prestack time migration and how to estimate these parameters followed by a 2D data example for illustrating purposes. Part II discusses the extension to 3D. The converted-wave kinematic response in inhomogeneous VTI media is separated into two
