Project Description

The overall objective of this project is to design, build and deploy in the field an intrinsic fiber optic sensor system for subsurface CO2 plume migration monitoring and above-zone leak detection. Intelligent Optical Systems will develop field-deployable intrinsic optic sensors with wireless communication capability, conduct sensor evaluation and demonstration in simulated subsurface conditions, and demonstrate subsurface sensor deployment and operation. Intelligent Optical Systems plans to deploy and demonstrate the sensor system in a 5,200 ft. deep well and demonstrate the feasibility of using the system to detect actual injection of CO2 at hydrostatic pressures up to 2,000 psi. It is anticipated that the system will be mature enough at the end of the project to be incorporated in monitoring wells in the injection projects planned for Phase III of the DOE Carbon Sequestration Program.

Project Benefits

This project will demonstrate fiber optic sensor prototypes for gas-phase and/or dissolved CO2 monitoring capable of withstanding corrosive liquids and elevated temperatures. The expect impact of this technology is lower operating costs through the use of improved monitoring devices to measure and verify the integrity of CO2 sequestration sites.
