“…These applications include various storage conditions with large or small injection volumes, deep or shallow reservoirs, and offshore or onshore settings (Jenkins et al, 2015). Common monitoring methods include seismic, microseismic, gravity, electrical/electromagnetic, downhole temperature -4-and pressure, well logging, InSAR, fluid sampling, tracer tests, aquifer geochemistry, soil CO2 concentration, and others (Hovorka et al, 2011;Jenkins et al, 2015;Harbert et al, 2016;Vermeul et al, 2016;Hannis et al, 2017;Daley and Harbert, 2019;Chadwick et al, 2019;Jenkins, 2020).…”

“…Monitoring techniques such as time-lapse seismic imaging and pressure gauges have been employed to assess pressure changes over time. The success of the Sleipner project in managing pressure dissipation has been attributed to the thorough geological characterization and the permeability of the cap rock [165].…”

Carbon capture and storage (CCS) is a critical technology for mitigating greenhouse gas emissions and combating climate change. CCS involves capturing CO2 emissions from industrial processes and power plants and injecting them deep underground for long-term storage. The success of CCS projects is influenced by various factors, including the regional pressure dissipation effects in subsurface geological formations. The safe and efficient operation of CCS projects depends on maintaining the pressure in the storage formation. Regional pressure dissipation, often resulting from the permeability and geomechanical properties of the storage site, can have significant effects on project integrity. This paper provides a state-of-art of the impact of regional pressure dissipation on CCS projects, highlights its effects, and discusses ongoing investigations in this area based on different case studies. The results corroborate the idea that the Sleipner project has considerable lateral hydraulic connectivity, which is evidenced by pressure increase ranging from <0.1 MPa in case of an uncompartmentalized reservoir to >1 MPa in case of substantial flow barriers. After five years of injection, pore pressures in the water leg of a gas reservoir have increased from 18 MPa to 30 MPa at Salah project, resulting in a 2 cm surface uplift. Furthermore, artificial CO2 injection was simulated numerically for 30 years timespan in the depleted oil reservoir of Jurong, located near the Huangqiao CO2-oil reservoir. The maximum amount of CO2 injected into a single well could reach 5.43 × 106 tons, potentially increasing the formation pressure by up to 9.5 MPa. In conclusion, regional pressure dissipation is a critical factor in the implementation of CCS projects. Its impact can affect project safety, efficiency, and environmental sustainability. Ongoing research and investigations are essential to improve our understanding of this phenomenon and develop strategies to mitigate its effects, ultimately advancing the success of CCS as a climate change mitigation solution.

“…If the underground geological formations are located on land, ground movements would be monitored through satellite measurements, such as InSAR [21][22][23]. If the underground geological formations are located offshore, then seabed movements should be monitored [24]. However, this recommendation has not yet become a standard procedure as it is for onshore storages, despite the conversion of several depleted gas and oil fields located offshore into storage being foreseen in the near future.…”

Underground fluid storage is gaining increasing attention as a means to balance energy production and consumption, ensure energy supply security, and contribute to greenhouse gas reduction in the atmosphere by CO2 geological sequestration. However, underground fluid storage generates pressure changes, which in turn induce stress variations and rock deformations. Numerical geomechanical models are typically used to predict the response of a given storage to fluid injection and withdrawal, but validation is required for such a model to be considered reliable. This paper focuses on the technology and methodology that we developed to monitor seabed movements and verify the predictions of the impact caused by offshore underground fluid storage. To this end, we put together a measurement system, integrated into an Autonomous Underwater Vehicle, to periodically monitor the seabed bathymetry. Measurements repeated during and after storage activities can be compared with the outcome of numerical simulations and indirectly confirm the existence of safety conditions. To simulate the storage system response to fluid storage, we applied the Virtual Element Method. To illustrate and discuss our methodology, we present a possible application to a depleted gas reservoir in the Adriatic Sea, Italy, where several underground geological formations could be potentially converted into storage in the future.
