Utilisation of Sub-Salt Attributes from 3D Prestack Depth Migrated Seismic Data - Examples from the Greater Mickey Area, Deepwater Gulf of Mexico

The majority of sub-salt seismic data throughout the Gulf of Mexico is characterised by poor signal to noise ratios degending on the complexities of structure and salt geometry. Therefore interpretation of sub-salt prospects is primarily done through structural mapping and qualitative use of attributes. An increase in demand for quantitative use of sub-salt attributes is expected as the industry continues to explore, appraise and develop future sub-salt discoveries (in the Gulf of Mexico and worldwide).
