Reflection Imaging

By mapping S reflections on the wellbore as they appear in time, NanoSeis can show you where the open fluid filled fractures are. Toe-ward fluid filled fractures are interpreted as frac-related and heel-ward fluid filled fractures are indicative of fluid filled natural fractures.

Moment Tensor Estimation - Strike Slip

The Moment Tensor Estimation examples above show a modeled amplitude for the focal mechanism plotted just above the observed microseimic event amplitudes. These examples match the radiation patterns very well for P-waves and are less clear for the S-waves because of the interference of the P-wave energy and complex S-wave strain.
