    • Pore Scale Modeling of Rock Properties and Comparison to Laboratory Measurements 

      Zhan, Xin; Schwartz, Larry; Smith, Wave; Toksoz, M. Nafi; Morgan, Frank Dale (Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)
      The microstructure of a porous medium and the physical characteristics of the solid and fluid phases determine the macroscopic transport properties of the medium. The purpose of this paper is to test numerical calculations ...
    • Fracture quality images from 4D VSP and microseismic data at Jonah Field, WY. 

      Willis, Mark E.; Willis, Kent M.; Burns, Daniel R.; Shemeta, Julie; House, Nancy J. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)
      Natural and induced fractures provide the only means of production in tight gas sand reservoirs. The objective of this work is to locate and characterize natural and induced fractures from the analysis of scattered waves ...
    • Improved Methods for Hydrofrac Event Detection and Phase Picking 

      Cornish, Bruce; Quirein, John; Ay, Erkan; Pei, Donghong; Zannoni, Steve; e.a. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)
      The ability to detect small microseismic events and identify their P and S phase arrivals is a key issue in hydraulic fracture monitoring because of the low signal-to-noise ratios. We propose a array-based waveform ...
