... is determined by threedimensional elliptical positioning technology; finally, the accurate reflector size is obtained by combining the observation records at different angles. The results of numerical analysis show that the proposed method can hopefully solve the problem of bad geological body location...

... to determine AVA. This approach naturally corrects for a multitude of other amplitude effects including reflector geometry and transmission losses, and it deals correctly with near-critical and post-critical reflections. FWI-based work-flows are consequently simpler than conventional work-flows, and AVA...
