Appl. of DAS for monitoring & verifying geological storage of CO2 - Dr. Don Lawton - DAS RCN Webinar

Applications of Distributed Acoustic Sensing (DAS) for monitoring and verifying geological storage of CO2 Presented by: Dr. Don Lawton, Dr. Jan Dettmer, and Dr. David Eaton of University of Calgary and the University of Calgary-CMC DAS team. Moderated by: Dr. David Eaton March 24, 2021 The Containment and Monitoring Institute (CaMI) of CMC Research Institutes Inc., in conjunction with the University of Calgary, has developed a comprehensive Field Research Station (FRS) in southern Alberta, Canada to facilitate and accelerate research and development leading to improved technologies for monitoring Carbon Capture, Utilization and Storage (CCUS) projects. Of particular importance is the ability to detect vertical migration of CO2 out of the storage complex and a change in phase of the CO2 from liquid to gas as it enters the shallow subsurface. Key goals for the FRS program are to develop and refine monitoring technologies to determine the detection threshold of gas-phase CO2 in the subsurface and to develop geophysical and other monitoring technologies to de-risk CCS in general. Distributed Acoustic Sensing (DAS) is actively being used to monitor CO2 injection at the site, with a 5 km loop of optical fibre installed in 2 observation wells and in a 1.1 km long trench. A schematic layout of the fibre is illustrated in Figure 1. The webinar will show the setup of a DAS interrogator at the site, acquisition of vertical seismic profile data using an envirovibe source, and examples of DAS monitoring data collected from the fibre loop. In addition, we will touch upon other DAS applications that the University of Calgary DAS team is working on, including monitoring of hydraulic fracturing, geothermal studies and geotechnical monitoring of dams.

Use of Distributed Acoustic Sensing is rapidly expanding in our community, prompting the initiation of an Distributed Acoustic Sensing Research Coordination Network to facilitate workshops, tutorials, and other opportunities for sharing ideas and resources. This webinar is one in a planned series on different topics within Distributed Acoustic Sensing.
