Inversion of Borehole Guided Wave Amplitudes for Formation Shear Wave Attenuation Values
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
A linear least squares inversion, based on analytic partition coefficient expressions, is
developed to estimate the fluid and formation shear wave Q values from spectral ratio
measurements-of the guided wave arrivals of ...
Shear Wave Logging In (Multilayered) Elastic Formations: An Overview
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
We perform the analysis of the dispersion and attenuation of the modes generated both
by a dipole and quadrupole source in a fluid filled borehole surrounded by a (multilayered) elastic formation. The displacement-stress ...
