Enabling permanent borehole microseismic monitoring
OptaSense DAS can also enable permanent borehole microseismic monitoring, especially of those larger magnitude events that originate at existing fault locations. Because of the broad bandwidth and high dynamic range capabilities of OptaSense DAS technology, the large, low frequency seismic signals generated at existing fault locations can be accurately measured.
In deviated wells, the long-array sensing aperture enables geolocation of recorded microseismic events. This service also allows you to monitor cross well communications which can result in under and over stimulated stages. With this real-time insight, you can determine diversion techniques or alternate stage spacing, as well as to fine tune perforation designs for optimal cluster efficiency.
