    • An Object-Oriented System for Full Waveform Data Processing 

      Larrere, Marc (Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
      A new approach to the processing of sequences of full waveform acoustic logs is investigated. The rationale for this approach is primarily based on the observation that processing and interpretation tasks strongly depend ...

    • Well-to-Well Log Correlation Using Knowledge-Based Systems and Dynamic Depth Warping 

      Lineman, D. J.; Mendelson, J. D.; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
      We present a novel system for well-to-well log correlation using knowledge-based systems and dynamic depth warping techniques. This approach overcomes a major drawback inherent in previous methods, namely the difficulty ...

    • Estimating Phase Velocity and Attenuation of Guided Waves in Acoustic Logging Data 

      Ellefsen, K. J.; Cheng, C. H.; Duckworth, G. L. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1987)
      Phase velocity and attenuation of guided waves have been estimated from multireceiver, full waveform, acoustic logging data using the extended Prony's method. Since a formation affects velocity and attenuation, estimating ...
