    • Multi-Shot Processing For Better Velocity Determination 

      Thompson, Delaine; Burns, Dan (Massachusetts Institute of Technology. Earth Resources Laboratory, 1989)
      We perform a technique called multi-shot processing on a section of 12-channel sonic logs in order to better resolve compressional and shear velocities. The data are from the ODP Leg 102 cruise, which occupied drill site ...

    • The Full Waveform Acoustic Log Inversion Problem 

      Garcia, G. H.; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1985)
      This paper presents the full waveform acoustic log inversion problem for a multisource - multireceiver tool logging a cylindrical fluid-filled borehole. The problem is formulated in the frequency-depth domain. A priori ...

    • Evaluation And Prediction Of Shear Wave Velocities In Soft Marine Sediments 

      Meredith, J . A.; Wilkens, R. H.; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1989)
      Shear wave velocities from full waveform acoustic logs were determined at DSDP Site 613 using the spectral ratio inversion method. Discrete shear wave velocities for a 350 meter interval at 0.5-2 meter depth increments ...
