    • Estimating the fracture density of small-scale vertical fractures when large-scale vertical fractures are present 

      Liu, Yuwei; Fehler, Michael; Fang, Xinding; Liu, Cai (Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
      When fractures are vertical, aligned and their dimensions are small relative to the seismic wavelength, the medium can be considered to be an equivalent Horizontal Transverse Isotropic (HTI) medium. However, geophysical ...

    • 3D Weak-Dispersion Reverse-Time Migration with a StereoModeling Method 

      Li, Jingshuang; Fehler, Michael; Yang, Dinghui; Huang, Xueyuan (Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
      The finite difference method has been widely used in seismic modeling and reverse time migration. However, it generally has two issues: large computational cost and numerical dispersion. Recently, a nearly-analytic discrete ...

    • High-dimensional wave atoms and compression of seismic datasets 

      Leinonen, Matti; Hewett, Russell J.; Zhang, Xiangxiong; Ying, Lexing; Demanet, Laurent (Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
      Wave atoms are a low-redundancy alternative to curvelets, suitable for high-dimensional seismic data processing. This abstract extends the wave atom orthobasis construction to 3D, 4D, and 5D Cartesian arrays, and parallelizes ...
