microseisgram

Nearest neighbour aligned seismic traces image

The key components of the microseisgram core include:

  • A fully specified relational database provides the foundation for the software
  • Multi format data reading, including SEG, SUDS, SEED, SEEDlink & SAC
  • Seismogram viewing & analysis, incorporating user-specified pre-processing templates
  • Viewing of vendor picks & hodograms
  • Multiple picking modes, allowing rapid array-based picking or detailed waveform analysis
  • Event location using either a 1D linear array (eg frac mapping) or any 3D array geometry
  • Guided auto-picking & event locations through trace migration analysis
  • Source parameter analysis, including Moment (Mw), Local (ML) & Duration (MD) Magnitude
  • Covariance (linearized) or Monte Carlo (non-linear) error ellipsoids
  • Focal mechanism analysis using double-couple fault plane solutions or Moment Tensor (MT)
  • 3D viewing of events, velocity models, travel-time grids, error ellipsoids, wells & surfaces
  • Enhanced 3D visualization including, location misfit, semblance, raypaths & beach-balls
  • Graphical tools for import & editing of 3D velocity models
  • Import & triangulation of 3D surfaces
  • Production of 3D animations
  • Interactive link between the 3DViewer, event Catalogue & waveform display
  • Trace rotation (raw, geographic & radial/transverse components to ray path)
  • Receiver-Gather analysis with pick alignment, multiplet-analysis & cross correlation
  • Velocity model building, including horizontal & dipping layers, full 3D & anisotropic (VTI)
  • Interactive velocity model editing through click-&-drag adjustments
  • Scripting and batch-mode for automating processing sequences
  • Event detection/re-triggering allowing experiment replay using different trigger criteria
  • Data import & database building wizard
  • Diagnostics & 2D plotting module including time-history, scatter, histogram & contour plots
  • Waveform truncation & SEG2-M data export
