Abstract

Presence of Bhimanapalli limestone of middle Eocene age and basalts of early Paleocene age, in Krishna-Godavari basin, causes poor seismic energy penetration. This always results in an inadequate image of sub-surface corresponding to deeper formations. Long offset seismic data was acquired in Amalapuram block of KG basin for imaging of deeper objects. A 2D line from this data set was processed adopting different processing approaches. The study deals with various issues involved in imaging of deeper formations alongwith merits and demerits of various processing approaches and improvement observed.
