Conventional steam injection projects have long been an iconic process in the development of heavy oil reserves; nevertheless, they face significant challenges in terms of energy efficiency, environmental compliance, and economic viability. Factors such as oil price fluctuations, the imperative for an energy transition, and the push to reduce carbon footprints are hindering new or ongoing implementations of traditional steam injection technologies. In response to these challenges, hybrid methods, such as the combination of steam and flue gas, are emerging as an opportunity to optimize thermal processes to improve oil recovery, energy efficiency, and environmental sustainability and extend reservoir productivity life. Steam injection enhances oil recovery by reducing the viscosity of crude oil, improving oil mobility and facilitating its extraction. The utilization of flue gas in steam injection processes has a significant impact on oil recovery and energy efficiency, leveraging industrial byproducts. This not only lowers operating costs but also reduces environmental emissions, aligned with energy transition trends. Incorporating the flue gas into a steam-based process in heavy oil reservoirs has emerged as a promising thermally enhanced oil recovery strategy. This work presents a comprehensive review based on experimental, numerical, and field studies of hybrid steam and flue gas technology as an EOR process. The main recovery mechanisms associated with the process are analyzed. In addition, the laboratory equipment required for experimental evaluations is presented, and reservoir modeling, kinetic and compositional effects on reservoir fluids, and the reduction in heat losses in the steam injection process are discussed. Furthermore, field implementations are reviewed to evaluate lessons learned and experiences on an operative scale. The combination of steam and flue gas represents an opportunity for carbon utilization and geological carbon sequestration. This dual functionality underscores its potential to enhance oil recovery and address carbon-related environmental concerns.

“…Saline aquifer storage involves injecting gas into deep underground saline reservoirs that are permanently buried through the capping traps of geological formations. The mechanism of CO 2 storage in saline aquifers includes geological structure storage, residual gas storage, dissolution storage, and mineralization storage . The understanding of the CO 2 migration characteristics and mechanism in saline aquifers at the mine site is still incomplete, and how to characterize the microscopic seepage process of CO 2 storage in saline aquifers is of great significance to the mine site for further understanding of the storage mechanism in deep saline aquifers.…”

CO 2 storage in saline aquifers is an important measure for CO 2 capture and storage (CCS), which can effectively reduce greenhouse gases. Current studies on CO 2 storage in saline aquifers mainly focus on the storage mechanism, fluid migration process, reservoir pressure evolution, and injection feasibility, but the models used in the studies are mostly macroscopic models, and it is difficult to accurately describe the microscopic seepage process of CO 2 in the pore space. To address the above research problems, this paper adopts a finely processed two-dimensional model of the core pore structure based on numerical simulation methods to simulate the microscopic seepage process of the CO 2 storage process in saline aquifers at the pore scale. The research results show that during the displacement process, CO 2 injection breaks through rapidly along the main flow line while seeping upward under the effect of the oil−water density difference and advancing forward in an irregular slope, causing the gas saturation to increase continuously. In the suction process, under the action of gravity, saline water is transported forward along the slope. After CO 2 injection, it will preferentially diffuse into the large pore saline water. The chemical products are mainly located in the diffusion and dissolution zones of CO 2 in water. The increase in the injection velocity during the displacement process will reduce the gas breakthrough time at the outlet. During the suction process, the increase in the injection velocity is beneficial to accelerate the water displacement process and will result in a reduction in the residual gas storage rate. The increase in the water contact angle will result in a decrease in the suction process time and an increase in the residual gas storage rate. This study has important implications for understanding the CO 2 plume migration laws and the CO 2 storage mechanisms from a microscopic perspective at the mine.

“…In the case of saline aquifers, CO 2 storage is achieved by a process known as saline trapping. In this case, rocks act as a sponge, where the injected CO 2 remains trapped within the pore spaces 18 . To enhance its stability, CO 2 can be dissolved into saline water to increase its density and causing it to sink to the lowermost regions of the rock formation, thereby permanently entrapping the CO 2 19 .…”

Despite the efforts to transition to a low carbon economy, greenhouse gas emissions are surging to critical levels. Carbon dioxide removals (CDR) methods, such as direct air capture (DAC), have been gaining substantial public attention in the last few years. DAC is essential in curbing CO2 concentrations and achieving climate targets. It is said that DAC can be deployed at anywhere, but a throughout life cycle assessment (LCA) is imperative to prove its viability. Therefore, this paper aims to explore the feasibility of constructing a 1 $$\text{MT}_{{\text{CO}}_{2}}$$ MT CO 2 plant in Ireland, using Kinsale and Corrib gas fields as storage points. The results showed that the country is an ideal candidate for scaling up this emerging industry. The efficiency is primarily influenced by the construction of the pipeline section, given a reliable sources of heat and electricity. The study highlights the significant impact of distances to the storage points on feasibility, favouring counties near of the gas fields. In conclusion, Ireland has the potential to establish its own DAC industry.
