Silixa is proud to be sponsoring the UK CCUS and Hydrogen Decarbonisation Summit on 4–5 February 2020 in Birmingham, UK. The event will address the latest developments and opportunities across the Carbon Capture, Utilisation & Storage (CCUS) and Hydrogen sectors, and determine strategies for greater decarbonisation of the energy intensive industries.
Dr Anna Stork, Silixa’s Senior Geophysical Analyst, will also present a case study on Silixa’s fibre optic sensing-based distributed acoustic and temperature sensors, deployed for the first time as a continuous CO2 storage reservoir monitoring solution in Otway, Australia.
At geological storage sites, a permanent fibre optic cable installed in a CO2 injection or observation well can deliver on-demand high-resolution seismic data to confirm the location of injected CO2, so operational injection decisions can be made with confidence. The system’s high sensitivity eliminates the need for large seismic sources; making it more cost-effective and environmentally acceptable than traditional seismic methods.
During the injection process, the same fibre optic cable can passively monitor the area for small seismic events, termed microseismicity. The ground-breaking high sensitivity of the system also enables slow strain monitoring. Large strain variations and microseismicity during the injection process can indicate high pressure levels that lead to fracturing, potential leakage pathways for CO2. Delivering real-time data that pre-warns of such events is crucial. This is the capability offered by fibre optic sensing.
In summary, the system provides continuous long-term monitoring both near surface and throughout the entire CO2 storage site. On-demand time-lapse seismic data delivers information about the evolution of the CO2 plume in time and in addition it provides assurance on the integrity of the caprock and the well, ensuring maximum safety of any storage facility.
