Project Description

This project will develop cost effective monitoring tools that can be used to demonstrate safe, permanent storage of CO2 in deep geologic formations. Under this project, EPRI will conduct field trials to extend the use of fiber optics to new and innovative in situ measurements and applications supporting CO2 storage and utilization (Enhanced Oil Recovery), including detection of CO2 flow, migration, and seismic monitoring. The project uses Distributed Acoustic Sensor (DAS) arrays to detect and image the CO2 plume using seismic methods. In addition, the sensors have heat-pulse monitoring capability using Distributed Temperature Sensing (DTS) to detect vertical CO2 leakage along the wellbore and flow outside of the casing. EPRI will work on designing, fabricating, and acquiring monitoring data from fiber optic cable assemblies to be installed in wells at up to two field facilities.

Project Benefits

This project focuses on developing and demonstrating a new, improved, seismic geophysics monitoring technology for tracking the CO2 plume and detecting possible leaks in the subsurface. Improved seismic methods allow project developers to more confidently and cost-effectively ensure that the storage formation is being efficiently utilized, and the CO2 is permanently stored and improved monitoring will contribute to better storage technology thus reducing CO2 emissions to the atmosphere. Specifically this project will develop and field test a distributed fiber optic array which integrates both temperature measurement and seismic survey data acquisition.
