Experimental Verification of Acoustic Waveform and VSP Seismic Tube Wave Measurements of Fracture Permeability
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
A variety of established and experimental geophysical techniques was used to measure the vertical distribution of fracture permeability in a 229-meter deep borehole penetrating schist and quartz monzonite near Mirror Lake, ...
New Applications In The Inversion Of Acoustic Full Waveform Logs - Relating Mode Excitation To Lithology
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1986-01-01)
Existing techniques for the quantitative interpretation of waveform data have been based on one of two fundamental approaches: 1) simultaneous identification of compressional and shear wave velocities; and 2) least-squares ...
A Numerical Investigation of Head Waves and Leaky Modes in Fluid-Filled Boreholes
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1985)
Although synthetic borehole seismograms routinely can be computed for a wide range of borehole conditions, the physical nature of shear and compressional head waves in fluid-filled boreholes is poorly understood. This ...
