Abstract

Accurate depth imaging of subsurface is very important for reservoir characterisation and delineation of geological features. The quality of a migration image depends strongly upon the accuracy of the velocity model. This article focuses on both the aspects. An innovative work flow has been adopted using well tie tomography during the process of anisotropic velocity model building, which serves the purpose of imaging and depthing all together. In this present study Earth Study 360 has been used as imaging tool which is recently developed full-azimuth angle domain imaging and analysis system designed to image, characterize, visualize and interpret the total seismic wave field in all directions.
