Surveillance wells play a critical role in carbon capture and underground storage (CCUS) by offering continuous monitoring of stored carbon dioxide (CO2). These wells help ensure the integrity of the storage site, providing early detection of leaks, pressure changes, or other anomalies that could compromise safety. Effective monitoring is key for environmental protection, verifying CO2 sequestration success, and boosting public confidence in carbon capture technologies. Often, surveillance wells are repurposed former injector or producer wells with installed bottom-hole pressure gauges, enabling precise pressure measurements.
ScanWell’s interventionless technology enhances this monitoring process by verifying the accuracy of installed bottom-hole pressure gauges or by obtaining the same pressure measurements without the need for additional equipment in the wellbore. ScanWell’s solutions also enable real-time compositional analysis and trending, providing immediate insights into the well’s condition. Furthermore, ScanWell can evaluate leakage rates and conduct mini-production tests on these surveillance wells, allowing for the assessment of CO2 breakthrough and further optimizing storage management. This comprehensive approach ensures that CCUS operations remain safe, efficient, and compliant with environmental standards.
