The World’s Largest Continuous 3D Onshore and Offshore Seismic Survey Sets Ambitious Quality and Turnaround Targets

摘要

In 2017 the Abu Dhabi National Oil Company (ADNOC) made the decision to image the entire Emirate’s subsurface (onshore and offshore) with 3D seismic. In addition to covering areas little explored before, and refreshing old images with modern technologies, the goal is to explore specifically for unconventional resources and shallow gas. Imaging both shallow and deep targets, in areas known for low signal-to-noise ratio, requires intense field efforts and elaborate processing sequences. Acquisition started in late 2018 and is scheduled to finish early 2022 with a final image delivery two years later. This is an extremely tight timeline considering the almost 90,000 km2 to be covered.
