Revolutionizing CCS Monitoring: DAS, Elastic FWI, and Microseismic for Enhanced CO2 Plume Tracking

Summary Distributed Acoustic Sensing (DAS) technology is revolutionizing reservoir monitoring in Oil & Gas and carbon capture and storage (CCS) applications. By using fiber optic cables as continuous sensors, DAS enables real-time, high-resolution monitoring of subsurface seismic activity, fluid dynamics, and reservoir performance. This document explores DAS applications in vertical seismic profiling (VSP), microseismic monitoring, elastic Full Waveform Inversion (FWI), and comprehensive reservoir monitoring. DAS-based VSP surveys offer cost-effective, detailed imaging of subsurface structures, while DAS-based microseismic monitoring provides realtime detection of microseismic events, enhancing reservoir performance assessment. Elastic FWI, utilizing DAS data, generates high-resolution subsurface images for precise CO2 plume tracking. Integrating DAS into CCS projects allows continuous monitoring of reservoir parameters, early detection of potential issues, and optimization of injection strategies. DAS technology thus enhances operational efficiency, environmental safety, and the transition to a low-carbon future.
