The transition of the oil and gas industry toward renewable energy demands effective plugging and abandonment (P&A) of aging reservoirs. The first step of the P&A process involves depressurizing the annulus and production tubing by clogging the flow path from the bottom of the well. Under challenging conditions, the P&A process faces significant difficulties due to downhole issues like mineral scale deposition. This study introduces an innovative thermoresponsive polymer gel designed to temporarily seal low-permeability chalk reservoirs by direct injection into the reservoir formation. The gel, synthesized from polyacrylamide through free radical polymerization and modified via partial amination, forms a stable three-dimensional network when combined with an organic cross-linker. This stability is achieved in response to the low-temperature ranges (60−80 °C) characteristic of these wells. This development not only facilitates temporary P&A but also presents a viable alternative to cement for P&A, potentially preserving wells for future CO 2 storage. It could also be used to seal off a reservoir after CO 2 injection, to avoid potential future CO 2 leak. The study's novelty lies in its focus on plugging low-permeability environments (around one millidarcy), a comparatively underexplored area. The gel's performance was evaluated under various pH, temperature, and salinity conditions, and in both fractured and nonfractured chalk core samples using a core flooding system and 3D imaging with microcomputed tomography for real-time monitoring. Our findings reveal significant insights into the gel's behavior, distribution, and the broader implications for its application in challenging geological settings.

Carbon Capture and Storage (CCS) is recognized as a potent strategy for managing the accumulation of human-generated CO2 in the atmosphere, helping to alleviate climate change’s effects. The CO2 gas is captured from the point source through methods such as pre-treating fossil fuels, oxy-fuel combustion, or post-combustion capture; thereafter; it is transported to a storage location and injected into geological formations. This article provides an overview of carbon dioxide capture and sequestration, focusing on its key principles, technologies, associated risks, and challenges. Direct Air Capture (DAC) and Scalable Modelling, Artificial intelligence (Al), Rapid Theoretical calculations SMART technologies are detailed as emerging and promising approaches to CO2 capture. Numerous pilot and commercial projects commissioned to manage carbon dioxide emissions are presented. Additionally, the paper explores approaches combining geological, geophysical, geochemical, and environmental monitoring techniques to ensure the secure and sustainable storage of CO2 underground. These are essential to address uncertainties, minimize risks, and build public confidence in CCS as a viable climate mitigation strategy. The successful deployment of these technologies on a global scale will require continued innovation, particularly in the areas of monitoring, risk management, and public engagement. Emerging technologies such as AI and SMART systems could play a crucial role in enhancing the efficiency and safety of CCS operations. However, the integration of these advancements with existing infrastructure and regulatory frameworks remains a challenge. Ultimately, a multi-disciplinary approach, combining technological, economic, and regulatory perspectives, will be vital to realizing the full potential of CCS in combating climate change.
