High Resolution Velocity Analysis and its applications to Pore Pressure Attribute Calculations

Detailed study of the Phase and Amplitude of wavelets in the migrated gathers<br>events can be utilized to obtain a very high spatial resolution velocity model. The<br>methodology is based on demanding that the analytically extended intercept and<br>gradient, computed over a limited angle range, are in phase (Swan 92, Swan 97). The<br>automation of this methodology provides us with dramatically flat migrated gathers plus<br>a very high-resolution 3D velocity field.
