N-05 IMAGING OF 4C DATA IN DEPTH – RESIDUAL VELOCITY ANALYSIS AND ANISOTROPY PARAMETER ESTIMATION Introduction The goal of this study is to produce structurally consistent PP and PS images of the Alba reservoir (located in the Central North Sea UK block 16/26) that are suitable for joint interpretation and inversion. Our approach is to image PP and PS data in depth rather than in time so that the need for image correlation and re-stretching is minimized. Our Pre- Stack Depth Migration workflow for multicomponent data consists of three steps: (1) isotropic imaging of PP and PS data; (2) derivation
