Interpreters of seismic datasets are always looking for greater resolution and higher frequencies. It often happens that they zoom into the data further than the dataset can accommodate. When they do this, they wind up looking at either a fragment of a seismic wavelet, or some very coarse, pixilated view of the geology. It seems interpreters want as much resolution as the dataset will allow.

We now have the ability to provide greater resolution, higher frequency images from the same input datasets. This will provide far more information to interpreters and geologists particularly in those areas of interest where productive wells may be drilled.

Using patented technology developed by N.S. Neidell & Associates we can increase the frequency content and the resolution of the migrated seismic dataset dramatically. Tsunami Development is the exclusive provider of commercial software based on this technology.

Salt Flank
Figure 1	Figure 2	Figure 3	Figure 4
Figures 1 and 2 show a comparison of the zoomed in area of the salt flank displayed as seismic wavelets. It is obvious that Figure 2 has higher frequency content and more detail. The traditional image is output at a 4ms sample rate, and at a 110ft x 110ft spatial sampling. The High Definition image is output at a 1ms sample rate, and at a 27.5ft x 27.5ft spatial sampling. From the wiggle trace display it is a bit difficult to appreciate the differences we see.		If we look at Figures 3 and 4, we see this same zoomed in area displayed as variable density display. In this comparison we see more clearly what is happening. The image in Figure 3 has been zoomed in to the point that we are seeing a very blurry and pixilated image. We see a blurry image of the salt flank and the intersecting sediments. The image in Figure 4 shows a much clearer, more complete image of the salt flank and the intersecting sediments. Figures 2 and 4 are displays from a much more informative dataset for the geologist and interpreter.
