Uncertainty in surface microseismic monitoring [PDF]
ASEG Extended Abstracts, 2013 Uncertainty in a migration based approach to surface and near surface microseismic monitoring occurs in two ways: uncertainty in the validity of detected events and uncertainty in the estimated position of the event. Synthetic modeling and comparison to case studies show that sign-to-noise-ratio is a key indicator of both types of the uncertainties. In
