S wave attenuation and dispersion in partially saturated rocks

posted Jul 25, 2017, 7:47 AM by Nisar Ahmed

Hello,

Does anyone know that how to compute S wave attenuation and dispersion (due to WIFF) in partially saturated rocks (isotropic)?

Ultrasonically-Enhanced static apparatus review

Hello

I am wondering if there is any recent review on designs of oedometer/triaxial apparatuses for rock incorporating ultrasonic transducers

Transversely isotropic acoustics: Does anyone know a reason for difference between Vsv(90) and Vs(0)

posted Mar 13, 2016, 11:48 PM by Omri Shitrit   [ updated May 11, 2016, 4:27 AM by IARP Admin ]

The usual case is that Vsv(90) equals Vs measured in the bedding-normal direction, but more than once it was found to be different. Couldn't find a satisfactory treatment.  Have any Ideas?

Thomson's parameters for anisotropy

In case if we do not have core plugs and also unable to find Thomson's parameters during seismic data processing, how can we calculate these ones (eta, epsilon etc.) from sonic log? Please share your views, literature and numerical formulas. Thanks

What are unresolved issues in rock physics?

At the end of the 3IWRP workshop in Perth, Australia, one of the popular topics of discussion was “What do you think are unresolved issues in rock physics?” I would like to continue and extend the discussion to a wider audience who did not attend the workshop. 


Please share your thoughts.
