What is FAZ?
Full-azimuth (FAZ) seismic data is data acquired over 360 degrees of azimuth over the full offset range. The subsurface geology is sampled in all directions and at all required offsets to give the optimum dataset. There are no compromises. Why does the industry need FAZ? FAZ data improves imaging in areas of complex structures, providing more detailed illumination for fracture and fault mapping, and it will improve our understanding of anisotropy and anisotropic velocity models. FAZ data is now readily achievable on land and at sea using efficient techniques and technology developed by WesternGeco. How do we acquire FAZ? On land the introduction of the WesternGeco UniQ integrated acquisition system, which is capable of recording up to 150,000 live channels of point-receiver seismic data, enables very large spreads to be deployed and therefore allows FAZ data to be acquired using any of today’s efficient source techniques.
