E. Interpreted original and EagleEye image.
To solve.
This is a continuation of a couple of posts enlarging on the original LinkedIn post by Bill Wepfer https://www.linkedin.com/in/bob-watchorn-97b95624/recent-activity/comments/. There has been some spirited discussion on whether EagleEye picks up the same (or similar structures) as an accomplished seismic interpreter can distinguish, is it of use in seismic interpretation?.
Method.
On the top left are a slightly enhanced original seismic section and on the top right the same one that was interpreted by me.
I’m an accomplished interpreter but have not done much ‘raw’ seismic image interpretation. I’ve been told it requires a lot of practice and know-how to read the special basin signatures which follow a pattern. So, it would be good if an accomplished seismic interpreter also interpreted the image to see the differences.
On the bottom left is an EagleEye image enhanced to highlight the structural geology. This enhancement method has produced valid geology in very many well documented areas and there is much detailed geology seen. This image was not interpreted by me but the interpretation from the original image was draped over it to see how they correlate.
Conclusions.
There is a strong correlation between the structures in the two images.
Interpreting the first original image is a bit hit and miss for an amateur because the structures are not defined but consist of colour changes, line thickness change, indistinct oblique structures and faded areas. I believe this is what geophysical interpreters have to use. To my estimation the lack of hard geology gives these interpretations a lower confidence level than ones based on hard structural geology.
The EagleEye image has detailed geology. Is this real??
The draped interpretation from the original image correlated in direction and length of structure in the EagleEye image. There were many other structures generally in the same directions that could be interpreted with great confidence. If these structures are real, then the confidence in the EagleEye interpretation would be far greater than the raw seismic interpretation. If what you are looking for is associated with a specific structural regime then EagleEye takes the guesswork out of the equation.
Comments by seismic interpreters are always welcome.
