ESG has a long history of dedication to research and innovation.  In 2013, ESG was awarded US patent 8,605,544 for its proprietary Hybrid™ passive seismic deployment strategy.  The Hybrid™ Seismic Sensor Network combines the use of high frequency and low frequency passive seismic sensors in borehole and near-surface arrays to accurately monitor induced seismicity from -3 to +3 in moment magnitude. ESG currently holds 4 patents with another 4 pending.  Spectraseis holds 10 patents.
