    • Estimation Of Nonorthogonal Shear Wave Polarizations And Shear Wave Velocities From Four-Component Dipole Logs 

      Nolte, Bertram; Cheng, Arthur C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1996)
      Polarizations of split shear waves and flexural borehole waves are most commonly estimated from four-component data using the rotation technique of Alford (1986). This method is limited to the case of the two polarizations ...

    • Untitled 

      Cheng, Arthur C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1996)
      This is the second year we have combined the work of the Logging and Reservoir Delineation groups at the Earth Resources Laboratory. In the first part of this report, we present work related to logging and petrophysics, ...

    • Modeling Of Seismoelectric Effects In A Borehole 

      Haartsen, Matthijs W.; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1995)
      We present a method to simulate the propagation of seismic and converted electromagnetic waves generated by a mechanical borehole source embedded in a layered poroelastic medium. The electroseismic conversions occur at ...
