Abstract

Imaging of basement and identification of fractures, connectivity and their distribution is a challenge particularly in OBC data. Fractured basement has played an important role for hydrocarbon discoveries. Ray based, multi arrival, Common Reflection Angle Migration (CRAM) depth imaging technology may provide the solution for generating high resolution, amplitude preserved, angle-dependent reflectivity gathers in local angle domain (LAD by uniform illumination at the subsurface image point from all directions. We have used this advance depth imaging technology on a huge volume of OBC data pertaining to Mumbai High Field
