We have worked for several years in Hydraulic Fracturing Monitoring. Special instruments and software have been designed and manufactured for this application. Our sensors are installed in the surface of the oil field, usually according a dense grid topology, and the recorded signal either stored locally or being transmitted in real time to our processing centre. This article presents the instruments & software being used in Hydraulic fracturing.
