Publicly Released 'SMAART' Data Sets, available to the Geophysical Industry:
( In cooperation with TNO and DELPHI )
1. Pluto 1.5 Pluto 1.5 is an elastic dataset released in November 2000, that
contains realistic free surface and internal multiples over a structure
that is relatively easy to image.
2. Sigsbee 2A Sigsbee 2A is an constant density acoustic dataset released in
September 2001, that does not contain free surface multiples and almost
no internal multiples due to very low contrast water bottom, but it is
over a sub-salt structure that is difficult to image.
Sigsbee 2B - Free Surface (FS) and Sigsbee 2B - No Free Surface
(NFS) use the same structural model as Sigsbee2A but the velocity
contrast at the water bottom has been increased to a normal level thus
generating significant internal and FS multiples. These datasets are
released in October 2002. The Sigsbee2B dataset is featured in paper
SP3.8 "Observations from the Sigsbee2B synthetic dataset" at the 2002
SEG meeting in Salt Lake City.
5. Ziggy Ziggy is a simple 3D numeric model, which like the Sigsbee
datasets, is modeled after salt structures on the Sigsbee scarp in the
Gulf of Mexico. The model is roughly 40 km E-W by 50 km N-S by 10 km
deep. There is no synthetic data to accompany this model.
