BACKGROUND Borehole seismic Surveys have become among the most versatile of
downhole measurements used in the hydrocarbon industry. Originally, borehole seismic …

A technique includes obtaining seismic data acquired by seismic sensors of a composite
seismic signal that is produced by the firings of multiple seismic sources. The technique …

A method for managing a fracturing operation. In one implementation, the method may
include positioning one or more sources and one or more receivers near a hydrocarbon …

A technique includes determining at least one parameter that characterizes a seismic survey
in which multiple interfering seismic sources are fired and seismic sensors sense energy …

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 …

Some aspects of what is described here relate to seismic data analysis techniques. A
seismic excitation is generated in a first directional wellbore section in a subterranean …
