    • Experimental studies of the acoustic wave field near a borehole 

      Zhu, Zhenya; Liu, Xien; Gu, Chen; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
      A monopole or a dipole source in a fluid borehole generates acoustic waves, part of which propagate along the borehole and the other part enter the formation propagating as P- or S-waves. The refracted waves propagating ...

    • Seismic characterization of reservoirs with variable fracture spacing by double focusing Gaussian beams 

      Zheng, Yingcai; Fang, Xinding; Fehler, Michael (Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
      Fractured reservoirs account for a majority of the oil production worldwide and often have low recovery rate. Fracture characterization is important in building reservoir flow models for enhanced oil recovery. Information ...

    • Time-stepping beyond CFL: a locally one-dimensional scheme for acoustic wave propagation 

      Zepeda Nunez, Leonardo Andres; Hewett, Russell J.; Rao, Minghua Michel; Demanet, Laurent (Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
      In this abstract, we present a case study in the application of a time-stepping method, unconstrained by the CFL condition, for computational acoustic wave propagation in the context of full waveform inversion. The numerical ...
