In recent years, advanced and integrated seismic processing and interpretation workflows have been adopted in ADNOC. The application of new processing routines to legacy seismic data has shown to be valuable in improving the quality of the seismic data. This improvement has had a positive impact on our understanding of complex geological settings, in particular in areas where salt movement has had an influence on the structural framework of the field.
In this paper, case studies are presented for salt-related structures in Abu Dhabi. Salt structures have been classified into three classes according to their complexity and each of these classes asks for a different type of seismic data volume and a different interpretation workflow. With the help of better reprocessed seismic data and seismic attribute analysis, complex structural uncertainties are better appraised, allowing less operational problems in wells due to drilling through faults and more optimal field development plans.
