ESG Solutions Improves Understanding of Hydraulic Fracture Effectiveness using Integrated Surface and Downhole Seismic Monitoring

Example surface equipment including an acquisition case, battery pack and surface sensor.  Solar panels may be used instead of a battery pack.  Typically, each surface acquisition unit is connected to one 3-component 4.5 Hz geophone and one 3-component FBA.

ESG Solutions, an industry leader in microseismic technology and services successfully conducted multiple hydraulic fracture monitoring projects within North America using its patented Hybrid™ Seismic Sensor Network.  The innovative approach integrates traditional downhole microseismic with surface and near-surface based induced seismicity (IS) arrays to accurately evaluate large and small-scale seismicity in one comprehensive system.  Operators benefit from improved insight into fracture development with minimal added cost to the microseismic program.

Microseismic monitoring effectively measures small-scale micro-earthquakes during hydraulic fracturing; however typical microseismic geophones are not optimal for detecting larger magnitude induced seismicity.  ESG’s Hybrid™ solution deploys low frequency sensors in near-surface arrays to accurately capture large magnitude events, and integrates the results with time-synchronized downhole microseismic data.  This unique approach builds on ESG’s capabilities in advanced microseismic analysis and provides operators with new information about fault activation and fracture effectiveness.

Correctly measuring seismic events using the right equipment is critical to gaining meaningful interpretation of seismicity, particularly for operators who rely on microseismic data to design future stimulation programs. 

ESG has deployed multiple Hybrid™ Seismic Networks throughout North America and the Middle East to monitor applications such as hydraulic fracturing, steam injection, hydrocarbon storage and waterflooding and forecasts increasing demand for these configurations over the coming year.
