Abstract

South of Nambar area, has become very promising exploration target in the South Assam Shelf of A&AA Basin due to recent hydrocarbon finds in the Bokabil formations of Neogene in the Nambar area. 3D seismic surveys have been carried out to map the reservoir sands in south Namabar area. 3D data were acquired using End-on Slant and Orthogonal shooting geometries during 2003-04 and 2004-05 respectively. The present paper deals with a comparison between various attributes of the shooting geometries and their effects on the data quality. The processed data quality is also compared and it is observed that orthogonal shooting geometry has provided better data quality
