The 1st International Workshop on Microseismic Technology featured contributions from the industry and academic institutions around the world to all aspects of microseismic technology.

About

The production of oil and gas from unconventional reservoirs relies on hydraulic fracturing as a means for increasing the naturally low permeability of tight formations to levels that make the exploitation of such reservoirs economically viable. When formations are hydraulically fractured, they tend to emit elastic energy in the form of micro-earthquakes, whose monitoring can yield valuable information about the volume of fractured rock, reveal the state of stress of a reservoir, and help mitigate seismic hazard. Microseismic monitoring is an emerging technology that faces unique geophysical challenges and offers information that improves our understanding of unconventional reservoirs.
