Enhancing the Imaging Quality of Pay Sands and Improving the Deeper Paleocene and Cretaceous Sediments Through Advancements in Seismic Processing and Full Azimuth Imaging from Land & OBC Data - a Case Study from KG Basin, India
The latest advancements in seismic processing and imaging, such as geostatistical interval velocity derivation and full-azimuth imaging, have improved many geologically complex and structurally deeper sediments.
In this study, a full-azimuth imaging tool combined with a geostatistical interval velocity was used in the KG Basin, where the subsurface is structurally complex. Significant improvements were observed.
