Abstract

Seismic data acquisition in Upper Assam shelf region has always been challenging owing to socioenvironmental issues. These challenges are now coupled with fast infrastructure development in the region such as the building of roads and housing constructions. Hence, it is imperative to extract maximum benefits out of the vintage datasets through re-processing as it is time-effective, efficient and lower-cost strategy. The objective of this study is to illustrate the extent of benefits possible through reprocessing of legacy seismic data through the application of current seismic imaging algorithms. This work showcases a case study from Upper Assam Shelf Basin, where re-processing was carried out on 3D seismic data acquired in the 1990
