Abstract
An electro acoustic technology (EAT) based micro seismic sensor and tiltmeter system and method is described for the measurement of minute deformations in downhole formations caused by hydraulic fracturing or other sources of pore pressure changes. A number of sensor arrays are described that are installed in clamp-on EAT devices installed in tool wells located in close proximity to hydraulically fractured wells.
