    • Comparison of microearthquake locations using seismic interferometry principles 

      Melo, Gabriela; Malcolm, Alison E.; Fehler, Michael (Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
      Mapping, localization, and general characterization of problems in reservoir fracture systems is one of the most important in oil, gas, and geothermal energy production. One way to study and monitor these fracture systems ...
    • Multipole seismoelectric logging while drilling (LWD) for acoustic velocity measurements 

      Zhu, Zhenya; Wang, Jun; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
      In seismoelectric well logging, an acoustic wave propagates along a borehole and induces electrical signals along the borehole wall. The apparent velocities of these seismoelectric signals are equal to the formation ...
    • Seismic characterization of fractured reservoirs using 3D double beams 

      Zheng, Yingcai; Fang, Xinding; Fehler, Michael; Burns, Daniel R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
      We propose an efficient target-oriented method to characterize seismic properties of fractured reservoirs: the spacing between fractures and the fracture orientation. We use both singly scattered and multiply scattered ...
