    • Converted Phase Elastic Migration Velocity Analysis 

      Shabelansky, Andrey Hanan; Malcolm, Alison E.; Fehler, Michael; Shang, Xuefeng; Rodi, William L. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
      Multi-component elastic seismic data collected at large offsets have the potential to be used in seismic imaging and velocity analysis. In this study, we present an approach for converted-phase elastic-transmission migration ...
    • Reverse Time Migration in the presence of known sharp interfaces 

      Richardson, Alan; Malcolm, Alison E. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
      We propose using the forward propagated source wave to create synthetic receiver data on the surfaces of the computational domain where real receiver data is not available as a means of exploiting known information about ...
    • A unified Bayesian framework for relative microseismic location 

      Poliannikov, Oleg V.; Prange, Michael; Malcolm, Alison E.; Djikpesse, Hugues (Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
      We study the problem of determining an unknown microseismic event location relative to previously located events using a single monitoring array in a monitoring well. We show that using the available information about the ...
