    • Models In LWD Applications 

      Rao, V. N. Rama; Burns, Daniel R.; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)
      A model for a fluid-filled borehole with an LWD tool is used to identify and analyze the monopole, dipole, and quadrupole modes that are present. The modes can be classified into three groups and have dispersion behavior ...

    • In Situ Permeability Estimation: A Comparison Between Acoustic And NMR Logs 

      Chen, Wei; Burns, Daniel R.; Tang, Xiao-ming (Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)
      Permeability estimates from acoustic logs (Stoneley waves) and NMR logs were compared using data from a geologic section consisting of sandstone and shale beds. The permeability results show very good correlation for ...

    • Formation Stress Estimation Using Standard Acoustic Logging 

      Huang, Xiaojun; Sinha, Bikash K.; Toksoz, M. Nafi; Burns, Daniel R. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)
      In situ formation stress directions and magnitudes are estimated by inverting the borehole flexural and Stoneley dispersions obtained from standard acoustic logging data (dipole and monopole logs). The underlying procedure ...
