      Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)
      This report contains the results of work completed during the twelfth year of the Borehole Acoustics and Logging Consortium in the Earth Resources Laboratory at M.LT. This year we have achieved one of our major goals in ...

    • Borehole Wave Propagation In Isotropic And Anisotropic Media I: Finite Difference Method 

      Cheng, Ningya; Cheng, C. H.; Toksoz, M. N. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1994)
      In this paper we developed a 3-D finite difference method to simulate wave propagations in an isotropic medium. The wave equation is formulated into the first-order hyperbolic equations by using velocity and stress and ...

    • Location Of Microearthquakes Induced By Hydraulic Fracturing 

      Rodi, William; Li, Yingping; Cheng, C. H. (Massachusetts Institute of Technology. Earth Resources Laboratory, 1993)
      This paper examines the problem of locating microearthquakes induced by hydraulic fracturing using seismic arrival time data. In addition to the use of absolute arrival times measured for individual events, we consider ...
