Description
  • We developed a methodology to obtain a consistent velocity model from calibration shots or microseismicity observed on a buried array. Using a layered 1D isotropic model, we invert P-wave arrival times to obtain effective (constant) anisotropic parameters with vertical axis of symmetry (VTI). The joint inversion of selected events shows a largely reduced RMS error and Thomsen anisotropy parameters epsilon of 0.15, and delta of 0.05. These values allow us to locate microseismic events from multiple hydraulic fracture treatments separated across tens of thousands of feet with a single velocity model.
