    • Predicting stress-induced anisotropy around a borehole 

      Fang, Xinding; Fehler, Michael; Zhu, Zhenya; Chen, Tianrun; Brown, Stephen; e.a. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
      Formation elastic properties near a borehole may be altered from their original state due to the stress concentration around the borehole. This could result in a biased estimation of formation properties but could provide ...
    • Reservoir fracture characterizations from seismic scattered waves 

      Fang, Xinding; Fehler, Michael; Zhu, Zhenya; Zheng, Yingcai; Burns, Daniel R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
      The measurements of fracture parameters, such as fracture orientation, fracture density and fracture compliance, in a reservoir is very important for field development and exploration. Traditional seismic methods for ...
    • Source-Indexed Migration Velocity Analysis with Global Passive Data 

      Burdick, S.; de Hoop, M. V.; van der Hilst, Robert D. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
      The reverse-time migration of global seismic data generated by free-surface multiples is regularly used to constrain the crustal structure, but its accuracy is to a large extent determined by the accuracy of the 3-D ...
