  • Pore Scale Modeling of Rock Properties and Comparison to Laboratory Measurements 
    Smith, Wave; Schwartz, Larry; Toksoz, M. Nafi; Morgan, Frank Dale; Zhan, Xin (Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)
    The microstructure of a porous medium and the physical characteristics of the solid and fluid phases determine the macroscopic transport properties of the medium. The purpose of this paper is to test numerical calculations ...
  • Pore-Scale Simulation Of Experimentally Realizable, Oscillatory Flow In Porous Rock 
    Olson, John F. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)
    We report new simulations of oscillating flow in porous rock. Our goal is to better understand the frequency dependence of pore-scale fluid motion, which should ultimately help us to interpret attenuation and electroseismic ...
  • The propagation and linkage of normal faults: Insights from the Strathspey-Brent-Statfjord fault array, northern North Sea 
    McLeod, Aileen E.; Dawers, Nancye H.; Underhill, John R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2001)
    Through examination of the scaling relations of faults and the use of seismic stratigraphic techniques, we demonstrate how the temporal and spatial evolution of the fault population in a half-graben basin can be accurately ...
  • Propagation Of Flexural Waves In An Azimuthally Anisotropic Borehole Model 
    Zhu, Zhenya; Cheng, C. H.; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1993)
    Flexural waves generated by a dipole source have been studied theoretically and used to estimate the shear parameters of a formation. The basic principles and main properties of flexural waves propagating in a borehole ...
  • Quantitative tools for seismic stratigraphy and lithology characterization 
    Herrmann, Felix (Massachusetts Institute of Technology. Earth Resources Laboratory, 2001)
    Seismological images represent maps of the earth's structure. Apparent bandwidth limitation of seismic data prevents successful estimation of transition sharpness by the multiscale wavelet transform. We discuss the application ...
  • Radiation Patterns Of Compressional And Shear Transducers At The Surface Of An Elastic Half Space 
    Tang, X. M.; Zhu, Zhenya; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1992)
    The radiation patterns of an elastic wave field generated by circular plane compressional and shear transducers are derived using the method of steepest descent. These patterns contain both effects of the elastic half ...
  • Rapid 3-D Raytracing For Optimal Seismic Survey Design 
    Zhang, Jie; Lavely, Eugene; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 1997)
    A useful approach to optimal seismic survey design is to simulate the seismic response for a suite of a priori subsurface models and shot-receiver templates. The response can be used to evaluate many criteria such as ...
  • Recursive Imaging with Multiply-Scattered Waves Using Partial Image Regularization: A North Sea Case Study 
    Malcolm, Alison E.; de Hoop, Maarten V.; Ursin, Bjorn (Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
    As more resources are directed toward reverse-time migration an accurate velocity model, including strong reflectors, is necessary to form a clear image of the subsurface. This is of particular importance in the vicinity ...
  • Redatumming Through a Salt Canopy – Another Salt Flank Imaging Strategy 
    Lu, Rongrong; Willis, Mark E.; Campman, Xander; Ajo-Franklin, Jonathan B.; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2007)
    We describe a new short cut strategy to image the sediments and salt edge around a salt flank through an overburden salt canopy. We demonstrate its performance and capabilities on a synthetic acoustic seismic data from ...
  • Reflection Moveout Inversion For Horizontal Transverse Isotropy: Accuracy And Limitation 
    Al-Dajani, AbdulFattah; Alkhalifah, Tariq (Massachusetts Institute of Technology. Earth Resources Laboratory, 1998)
    Horizontal transverse isotropy (HTI) is the simplest azimuthally anisotropic model used to describe vertical fracturing in an isotropic matrix. Using the elliptical variation of P-wave normal-moveout (NMO) velocity with ...
  • Reflection Moveout Inversion In Azimuthally Anisotropic Media: Accuracy, Limitation, And Acquisition 
    AI-Dajani, AbdulFattah; Alkhalifah, Tariq; Morgan, Dale (Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)
    Parameter estimation from elliptical variations in the normal-moveout (NMO) velocity in azimuthally anisotropic media is sensitive to the angular separation between the survey lines in 2D, or equivalently source-to-receiver ...
