Casing Annulus Monitoring of CO2 Injection Using Wireless Autonomous Distributed Sensor Networks
This innovative sensor system uses radio frequency (RF) communication to provide real-time monitoring of conditions within and around wellbore cement. Embedded network of microsensors track temperature, pH, and detect gases such as CO₂ and methane (CH₄), transmitting data to the surface to enhance detection of potential leakage, loss of containment, and evaluating well integrity over time.
Key benefits include:
- Real-time, distributed measurements of cement conditions
- Lower-cost alternative to fiber optics with redundant data readouts
- Supports long-term environmental and enhances seismic monitoring
- Enables operators to enter a rapidly expanding market opportunity
