  • van der Hilst, Robert D.; de Hoop, Maarten V.; Shen, Peng (Massachusetts Institute of Technology. Earth Resources Laboratory, 2007)
    In seismic tomography, the finite frequency content of broad-band data leads to interference effects in the process of medium reconstruction, which are ignored in traditional ray theoretical implementations. Various ways ...
  • Kane, Jonathan; Herrmann, Felix; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2002)
    We present a non-linear method for solving linear inverse problems by thresholding coefficients in the wavelet domain1. Our method is based on the wavelet-vaguelette decomposition of Donoho (1992). Numerical results for ...
  • Kane, Jonathan; Herrmann, Felix; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2001)
    Solving linear inversion problems in geophysics is a major challenge when dealing with non-stationary data. Certain non-stationary data sets can be shown to lie in Besov function spaces and are characterized by their ...
  • Tang, X. M.; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1989)
    A laboratory experimental study has been carried out to investigate the mode trapping characteristics of a fluid-filled fracture between two elastic solids. Using a small circular cylindrical receiver of 2.7 mm diameter, ...
  • 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 ...

    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, ...

    Tezuka, Kazuhiko; Cheng, C. H.; Tang, X. M. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)
    This paper describes a propagator matrix formulation for the problem of the Stoneley wave propagation in an irregular borehole. This is based on a simple one-dimensional theory that is possible for the low frequency ...
