Special Issue Information
Dear Colleagues,
Greetings from the Guest Editor of the Special Issue of Energies on Energy Geomechanics.
We cordially invite you to submit your high-quality manuscripts to the Special Issue of Energies on Energy Geomechanics. This Special Issue focuses on rock mechanical aspects of energy engineering, encompassing petroleum engineering and alternative energy sources, such as geothermal, hydrogen, and nuclear energy.
Topics include, but are not limited to, the geomechanical aspects of:
- conventional and unconventional petroleum wellbores from wellbore construction to abandonment;
- conventional and unconventional petroleum reservoirs and surrounding strata during the hydrocarbon production;
- subsurface disposal of liquid waste and brine;
- CO2 sequestration;
- underground storage of energy, including hydrogen, synthetic methane, heat, compressed air, and natural gas;
- near-surface and deep geothermal energy production;
- nuclear waste management.
The manuscript may be a review paper or may be based on applied and fundamental studies using physical model testing, mathematical modelling, or field case studies.
We look forward to receiving your manuscripts for this Special Issue.

Title: Multi-Disciplinary Modelling for Risk Identification in Carbon Capture and Underground Storage (CCUS)

Abstract: There are increasing countries that are making commitments to attain net zero emissions in the future decades. Carbon Capture and Underground Storage (CCUS) can play crucial role in the transition to net zero. The objective of this paper is to identify and assess the risks associated with CCUS during the injection phase and after injection stops. The work integrates multi-disciplines such as seismic, rock physics, geology, petrophysics, fluid-flow, chemistry and geomechanics to identify the risks and suggest mitigation prior to these happening.
Carbon storage into geological formations is modelled using a 4D coupled Thermo-Hydro-Mechanical-Chemical (THMC) process, which accounts for fluid-flow (T-H), geomechanics (M), and chemical dissolution (C). The model assesses the storage capacity, identifies high-risk regions, optimizes injector location, evaluates the state of stress within faults and cap-rock and assess a monitoring strategy. The results include a risk map with low, medium, and high-risk zones, as well as a high-resolution near wellbore integrity simulation using a 3D model. This model considers both short and long-term behaviour, and the results indicate the need for ongoing monitoring during CCUS applications to mitigate residual risks.
This study highlights the need for ongoing monitoring during CCUS applications during storage phase and due to residual risks, that continue after injection stops. The 4D coupled Thermo-Hydro-Mechanical-Chemical (THMC) model provided a comprehensive assessment of the carbon storage process by identifying high-risk regions within the reservoir and optimizing injector location with respect to faults. The 3D near wellbore model demonstrated the existence of residual risk after the injection phase, which emphasizes the importance of ongoing monitoring techniques to mitigate potential risks. The risk map obtained from the model illustrated a simple yet effective way of identifying low, medium, and high-risk zones within the reservoir. Additionally, high-resolution near wellbore integrity simulations ensured short-term and long-term safety. These findings demonstrated the importance of accurate modelling and monitoring technologies within an integrated workflow for CCUS applications to ensure successful carbon storage and minimize potential risks.
