Permeability Estimation from Field Data
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
Strong correlations exist between core measured permeability values and the phase velocity and attenuation of the tube wave obtained from full waveform acoustic logs.
A number of authors have applied the Biot theory to ...
Logging in Multilayered Saturated Porous Formations
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
We present a general formulation based on the Thomson-Haskell method which allows
the study of complex models. The surrounding formation may be composed of several
coaxial porous shells or of a combination of both porous ...
Shear Wave Logging In Semi-Infinite Saturated Porous Formations
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
Recent theoretical and experimental studies have demonstrated the interest of using
non-axisymmetric sources, such as dipole and quadrupole, to record shear wave events
in any kind of formation (fast or slow). Non-axisymmetric ...
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 ...
