    • 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 ...

    • Subsurface Imaging with Reverse Vertical Seismic Pro les 

      Krasovec, Mary L.; Coates, Richard; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2001)
      A novel imaging process, referred to as vector image isochron (VII) migration, is specifically designed to reduce artifacts caused by arrays with limited apertures. By examining the assumptions behind generalized Radon ...
