Abstract
Microseismic monitoring of reservoir processes can be performed using
surface or near-surface arrays. We review the published technical
basis for the use of the arrays and the historical development of
the method, beginning with locating earthquakes through geothermal
exploration to the growing field of hydraulic-fracture monitoring.
Practical considerations for the array deployment and data processing
are presented. The road ahead for the technology includes a move
toward life-of-field buried arrays as well as opportunities for extended
interpretation of the data, particularly inversion for source-mechanism
estimation and measurement of anisotropy in the monitored subsurface.
