    • Inversion Of Travel Time For Velocity 

      Willis, M.E. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1983)
      Common source velocities and borehole compensated (BC) estimates have been used to obtain formation velocity estimates from full waveform acoustic logs (Willis and Toksoz, 1982). With both of these methods the ...

    • P And S Wave Velocity Determination 

      Willis, M. E.; Toksoz, M.N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1983)
      There are three general methods that can be used to determine formation velocities from full waveform logs. The first approach is to make use of the data from the entire waveform. This type of velocity analysis is performed ...

    • Approximate Effects of Off-Center Acoustic Sondes and Elliptic Boreholes Upon Full Waveform Logs 

      Willis, M. E.; Toksoz, M. N.; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1983)
      Full waveform acoustic well logging has become instrumental to hydrocarbon exploration because of its ability to determine in situ velocity information for P and S waves as well as the attenuation (or absorption) of seismic ...
