Topic:
Multi Sensor Acoustic Parameter Analysis (Mouse) System for Monitoring and Evaluation of Deep Drilling, Jetting, and Stimulation Operations

AE monitoring is based on the detection and conversion of elastic waves into electrical signals, which are typ-ically associated with a rapid release of localized stress energy propagating within a given material. Thus, it is a passive testing, logging, andanalysis method to evaluate changes in the properties and behavior of machines and mineral type materials such as rocks during operations. Such changes may be induced by drilling, jetting or other drilling methods and being recorded, located, and evaluated via an AE system. This is the core of GZB’s new development, the AE based, so-called Multi-Sensor acoustic parameter analysis (MoUSE) as the main con-trol and monitoring mechanism during rock breaking, drilling, jetting, and stimulation. AE signals generated during jetting or bit-rock interaction are being monitored and analyzed extensively using novel numerical methods, based on sound analysis and engineering applications.
