When California, USA-based utility company Pacific Gas and Electric (PG&E) required an accurate and reliable system for monitoring a large underground gas storage (UGS) field, it partnered with advanced sensing technology company, Paulsson to develop and field test a real-time 24/7 monitoring system. Paulsson is known for inventing, designing, manufacturing and deploying all-optical sensors into deep, high-temperature and high-pressure boreholes. In this instance, its solution was an acoustic and ultra-large aperture antenna based on fiber optic sensing technology, using distributed acoustic sensing (DAS) technology. Since installation, the system has achieved real-time gas flow detection and monitoring both in the well and in the formation, which is a world first for this type of application. The system has also recorded numerous small and large earthquakes from nearby faults and those as far away as Japan and Peru, providing valuable information about the UGS formation properties using these natural near and far seismic sources.
