Embodiments of using known source locations in seismic data processing are disclosed. In one embodiment, a method of locating a seismic event includes receiving location information for a plurality of known source events proximate the seismic event, and determining an estimated location of the seismic event using a relative locator constrained by the location information for the plurality of known source events.

Methods and systems for using known source events in seismic data processing

Microseismic mapping using buried arrays with the integration of passive and active seismic surveys provides enhanced microseismic mapping results. The system is initially set up by recording seismic data with the buried array installation while shooting a significant portion of the 3D surface seismic survey. The 3D surface seismic survey provides the following data: shallow 3D VSP data from the buried arrays; P-wave and converted wave data for the area covered by the buried array that benefits from the planned data integration processing effort; and microseismic data and associated analysis.
