Abstract
A comprehensive test is used to compare microseismic monitoring from surface, shallow well and downhole arrays. In particular, a long-aperture borehole array was deployed with sensors spanning from the reservoir depth to surface. This array allows tracking of microseismic signals and measurement of the signal degradation that occurs between the various normal monitoring configurations. The experiment is a unique opportunity to fundamentally understand the signal degradation, and hence the sensitivity differences between common microseismic array configurations.
