Dear Abdhesh,
 
 
In our personal communication:
 
This reply is just knowledge sharing reply not particularly meant to answer your question. I just want to share the thing hitting my mind. I believe you got enough great responses from this chain. Your question realy hit my mind. Delineating fluids via one techniques-one input type (e.g. SpecDecomp) is quite hard, obviously. I know its not 1:1 solution for our industry, I must say 1:x (one output: multiple input techniques). But there is a black box to tune the responses (via spectral decomposition whatever method we use) and that black box is multidiscipline thoughts (i.e. # of methods). To my knowledge, which exactly I want to share with you is this article http://www.cseg.ca/publications/recorder/2002/06jun/jun02-inside-the-box.pdf (haven't got enough upstream but idea is quite important for us). I believe you want to generate the same results as presented in the same artilce.
 
Do you have any access to a solution that transform the data into Waveform -> AI -> LMR (lamm'-mue)-> Fluid Static response?
 
I'm still trying to using direct equations (esp. for rock physics) in OpendTect (Proposed by J.P. Castagna and others) by using simple Mathematics attributes. And simple idea is that we must have the respective input variables (i.e. cubes e.g. AI). But I believe in results (as you quote delineating ...fuid effect) that should be improved after transformation into AI and then into fluid/rock specific property either by using approximated equations/attributes/NN or by including other measurements in account e.g. 4D/4C. Thats another issue; but we all know that 3D fluid approximation is basically static transformation.
 
 
Keep in touch.

Hi All,
 
I’m using CWT ( continuous wavelet transform) attribute in OpendTect. CWT – spectral decomposition technique delineating channel very clearly but I need some suggestions on it, “How can I see the fluid effect in the delineated channel??”
You advise will be very helpful…….
 
Thanks & regards,
Abdhesh
