“…The huge success in unconventional oil resource development not only led to the continuous growth of small and medium-sized exploration and development companies in the United States, − but also attracted the interest of large oil companies and international oil companies in the industry . They have set up joint ventures with small and medium-sized oil companies, acquired oil assets of small and medium-sized companies, or entered the unconventional oil field through company mergers . According to IHS, since 2006, the funds invested in unconventional oil fields in North America have been highly intensive, mainly leading to the transaction of tight oil assets, amounting to US $152 billion.…”

Tight sandstone and shale oil reservoirs are one of the most promising and realistic important oil exploration fields in the 21st century. The research on the development technology of tight sandstone and shale oil reservoirs has important theoretical and practical significance for the exploration and development of tight sandstone and shale oil reservoirs in China. First, this article introduces the distribution of tight oil in the world and calculates the recoverable reserves of tight oil technology worldwide. The review also introduces the current status of tight oil exploration and development in major countries such as the United States, Canada, and China, including the distribution of tight oil resources, the main parameters of tight oil basins, and tight oil production. Second, it analyzes the current development status of tight oil in the United States, summarizes the four main factors that led to the success of tight oil exploration and development in the United States, and points out the impact of the successful development of tight oil in the United States on the global oil supply and demand relationship. Third, in the review of the main development technologies for tight oil, the current status, application, and progress of the main development technologies for tight oil are summarized and analyzed, including horizontal well drilling, fracturing and transformation technology, microscale seismic diagnosis, gas injection, and other technologies. Finally, the development examples of tight oil such as the Bakun shale in the United States are analyzed, and the application effects and experiences of horizontal well volume fracturing in regions such as the United States are summarized.

“…For example, the SOFC technology development in China commenced relatively late, and the research on the SOFC technology in China has mainly taken the route of independent development, starting from 2007 when China started to research key materials and basic science related to the SOFC. In China, CBM is a very abundant resource associated with coal. − The extraction and utilization of CBM is very important, and a lot of research has been done on the enhancement of CBM production; − however, in the industrial chain of “exploration–extraction–utilization” of CBM, the utilization of low-concentration methane has been a key factor restricting the development of the industry. The SOFC has the unique advantage of being able to utilize CBM directly with high conversion efficiency, and its working principle is shown in Figure b.…”

With the growing global demand for clean energy, more and more attention has been given to the energy conversion efficiency of low-quality fuels. A solid oxide fuel cell (SOFC) is expected to be one of the ideal technologies for clean and efficient utilization of low-concentration coalbed methane (CBM) because it can achieve efficient utilization of low-quality fuels. This review examines the challenges of SOFC technology fueled by low-concentration CBM. In comparison to fuels such as hydrogen and natural gas, lowconcentration CBM usually contains a large number of other gas components in addition to methane, which reduces the chemical reactivity of CBM and leads to a decrease in the utilization efficiency. The effects of different carbon-containing fuels on the cell performance of SOFC have been investigated by a great deal of research, and the results reveal that methane tends to be the main source of carbon deposition, whereas oxygen-containing fuels can have a positive effect on carbon deposition. In the current SOFC technology fueled by hydrocarbon fuels, concentration polarization is also a major factor contributing to the lack of durability and stability of the cell, with the exception of carbon deposition and sulfur poisoning. In addition, the temperature and other operating environments also have different degrees of influence on the cell performance in the SOFC technology fueled by low-concentration CBM. Therefore, the development of cell materials and the optimization of the system structure of a low-concentration CBM-fueled SOFC are still key research directions for the future.
