Design and Implementation of Wide-Azimuth 4C OBC Seismic in the Arabian Gulf

A30 DESIGN AND IMPLEMENTATION OF WIDE- AZIMUTH 4C OBC SEISMIC IN THE ARABIAN GULF Abstract 1 We describe the design and implementation of a ~147 km 2 full fold (~250 km 2 surface area) wideazimuth multi-component (“4C”) 3D seismic survey over the Idd El Shargi North and South Domes offshore Qatar. This survey is being used to delineate fracture orientation and fracture density in producing carbonate Shuaiba reservoirs and is one of the few wide-azimuth marine 4C surveys over carbonate reservoirs. Challenges of seismic operations in these actively producing oil fields are presented along with methods to mitigate the impact
