AUTONOMOUS SYSTEM FOR HYDROFRACTURE MONITORING

摘要

A system includes a plurality of sensor assemblies that are adapted to be deployed in a wellbore and acquire sensor data indicative of microseismic activity due to a hydraulic fracturing operation in the wellbore. At least one of the sensor assemblies includes a command interface and at least one sensor and is adapted to use the command interface to identify a command stimulus that is communicated downhole and initiate an acquisition by the sensor in response to identifying the command stimulus.
