Project: Assuring integrity of CO2 storage sites through ground surface monitoring

Acronym SENSE (Reference Number: 299664)
Duration 01/09/2019 - 31/08/2022
Project Topic The primary objective is to demonstrate reliable, cost efficient CO2 storage monitoring using ground surface deformation detection combined with geomechanical models to provide information on pressure distribution and hydraulic behavior of the storage sites. The main objective will be addressed by answering the secondary objectives: 2.1.1 Demonstrate the ability for continuous and accurate monitoring of surface deformation for selected sites comparing satellite measurements, pressure sensors and tiltmeters with fiber optic technology 2.1.2 Develop geomechanical models for characterization of subsurface stress distribution, anisotropy and permeability calibrated by the detected surface movements 2.1.3 Develop innovative interpretation algorithms and inversion workflows, for data integration and cost efficient automatization for satellite data processing 2.1.4 Optimize sampling array configuration of ocean bottom sensors for cost efficiency, detectability and long term safety assurance.
Project Results
(after finalisation)
The main impact of this project will be the recommendations and monitoring strategy that result in inexpensive monitoring of large scale CO2 storage sites. Project partners will use case studies onshore and offshore to demonstrate how different monitoring techniques (satellite, GPS, geodesy for onshore and inclinometer, pressure sensor and fibre optics for offshore) can effectively reveal subsurface processes at a low cost. further impacts -demonstrating a new ocean bottom lander and a fibre optic strain cable solution at seafloor for very accurate and continuous monitoring of sea bottom above a pilot injection site (advance TRL to TRL6).Automation of satellite data processing which provides operators with quick information and timely decision making. Developing models and inversion algorithms that link surface deformation to subsurface hydrodynamics. Recommendations for ground monitoring: cost-effective and appropriate spatial-temporal resolution at seafloor/surface monitoring
