    • Effects Of Formation Stress On Logging Measurements 

      Huang, Xiaojun; Zhu, Zhenya; Toksoz, M. Nafi; Burns, Daniel R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2000)
      We show both theoretically and experimentally how stress concentrations affect the velocity field around a borehole surrounded by a formation with intrinsic ortohombic anisotropy. When F[subscript x] = F[subscript y], ...

    • Shear-Wave Reflection Moveout For Azimuthally Anisotropic Media 

      Toksoz, M. Nafi; Al-Dajani, AbdulFattah (Massachusetts Institute of Technology. Earth Resources Laboratory, 2000)
      The presence of azimuthal anisotropy causes shear wave propagation to split into fast and slow shear waves. The most common azimuthally anisotropic models used to describe fractured reservoirs are transverse isotropy ...

    • Imaging With Reverse Vertical Seismic Profiles Using A Downhole, Hydraulic, Axial Vibrator 

      Krasovec, Mary; Turpening, Roger; Paulsson, Bjorn; Haldorsen, Jakob; Coates, Richard; e.a. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2000)
      We present the analysis of a reverse vertical seismic profile (RVSP) acquired over a pinnacle reef in the northern Michigan reef trend. The survey exhibited two features of note: (1) a new, strong, downhole vertical ...
