oa 3D-2C OBC Multi-azimuth Seismic Data Processing and Its Applications for a Carbonate Field Offshore Abu Dhabi, UAE

A 3D-2C OBC multi-azimuth seismic data processing was conducted in a test area in a carbonate field offshore Abu Dhabi, United Arab Emirates with the main objectives: to demonstrate improvement of imaging; and to detect any HTI response. Three processing flows were designed to generate (i) conventional, (ii) full-azimuth and (iii) multi-azimuth cubes. The output cubes were evaluated qualitatively and quantitatively: (1) overall imaging analysis; (2) fault imaging analysis; and (3) HTI analysis. The results demonstrated improvement of imaging compared to traditional processing and detection of a certain HTI response. These encouraging results will be the incentive to apply multi-azimuth seismic data processing in carbonate fields offshore Abu Dhabi, United Arab Emirates.
