Heavy oil and bitumen resources are estimated to account for about 70% of the global oil reserves. Recovery of these resources economically and environmentally is crucial to satisfy the crude oil demand in the next few decades. Steam injection-based techniques encounter challenges of large water usage, high operating costs, and huge greenhouse gas (GHG) emissions. In-situ combustion, which utilizes the heat generated by oxidation reactions between crude oil and oxygen, is an alternative and promising thermal technique to recover heavy oil and bitumen resources with the expectation to reduce water usage and lower operating costs. But complexity of oxidation behavior and uncertainty of in-situ combustion (ISC) performance prediction have restricted the field application of the ISC process. This paper provides a comprehensive review of the most recent studies about the ISC process and updated field projects. Various experimental studies are first presented to investigate the oxidation mechanisms of crude oil and the ISC enhanced oil recovery (EOR) mechanism. Based on the experimental advances, recent progress on reaction kinetics models and field scale modeling of ISC is presented. Subsequently, currently active field projects have been updated to provide the best practice of field operation. Finally, future perspectives of ISC for heavy oil or oil sands recovery are identified with a focus on in-situ catalytic upgrading and hydrogen generation.

“…Safety and efficiency are also critical issues during UHS [65,66]. There are several factors that directly or indirectly contribute to the safety and efficiency of hydrogen storage in underground deposits, and these include the geochemical and microbiological interactions [67], geomechanical properties [68], and the petrophysical properties of the porous media [61].…”

Due to the increasing world population and environmental considerations, there has been a tremendous interest in alternative energy sources. Hydrogen plays a major role as an energy carrier due to its environmentally benign nature. The combustion of hydrogen releases water vapor while it also has a vast industrial application in aerospace, pharmaceutical, and metallurgical industries. Although promising, hydrogen faces storage challenges. Underground hydrogen storage (UHS) presents a promising method of safely storing hydrogen. The selection of the appropriate cushion gas for UHS is a critical aspect of ensuring the safety, efficiency, and reliability of the storage system. Cushion gas plays a pivotal role in maintaining the necessary pressure within the storage reservoir, thereby enabling consistent injection and withdrawal rates of hydrogen. One of the key functions of the cushion gas is to act as a buffer, ensuring that the storage pressure remains within the desired range despite fluctuations in hydrogen demand or supply. This is achieved by alternately expanding and compressing the cushion gas during the injection and withdrawal cycles, thereby effectively regulating the overall pressure dynamics within the storage facility. Furthermore, the choice of cushion gas can have significant implications on the performance and long-term stability of the UHS system. Factors such as compatibility with hydrogen, cost-effectiveness, availability, and environmental impact must be carefully considered when selecting the most suitable cushion gas. The present study provides a comprehensive review of different types of cushion gases commonly used in UHS, including nitrogen, methane, and carbon dioxide. By examining the advantages, limitations, and practical considerations associated with each option, the study aims to offer valuable insights into optimizing the performance and reliability of UHS systems. Ultimately, the successful implementation of UHS hinges not only on technological innovation but also on strategic decisions regarding cushion gas selection and management. By addressing these challenges proactively, stakeholders can unlock the full potential of hydrogen as a clean and sustainable energy carrier, thereby contributing to the global transition towards a low-carbon future.
