DUG MP-FWI Imaging can be used to illuminate the near surface, providing unsurpassed high-resolution images for interpretation and site characterisation.

In the example below, horizontal resolution at the seafloor has been improved by orders of magnitude!

This legacy dataset (late 1990s) was not acquired with shallow high-resolution in mind. It’s a conventional towed-streamer acquisition in a shallow-water environment.

DUG MP-FWI Imaging uses the entire wavefield, including all free-surface multiples. Multiples, normally considered as problematic noise (especially in a shallow-water setting!), illuminate the subsurface in complementary ways to primary reflections. The result is that the subsurface is sampled far more completely, and with a wider range of angles.

“DUG MP-FWI Imaging has delivered much better data quality and a more accurate velocity model. The shallow section is now clearly resolved, faulting better defined, major chronostratigraphic boundaries clearer and more laterally continuous, and we can now more reliably map the deeper section.”- Henry dodwell, Subsurface Manager, Panoro Energy

More signal. Higher resolution. Superior imaging.

How illuminating!
