The book "Chemical reagents and technologies for increasing oil recovery of reservoirs" edited by M. A. Silina and other authors are a unique publication that opens doors to the world of modern technologies and chemical solutions aimed at optimizing oil production processes. With an ever-increasing need for energy resources and the depletion of traditional fields, this book becomes a handbook for oil and gas industry professionals, as well as for undergraduate and graduate students studying relevant disciplines. The main theme of the book is focused on the use of chemical reagents in the process of increasing oil recovery. The authors consider in detail various technologies that allow not only to increase the volume of recoverable oil, but also to make this process more efficient and economically feasible. The book covers a wide range of issues - from the choice of reagents to their impact on the geological and physico-chemical properties of the layers. The reader will be able to learn about new approaches to injection of reagents, as well as methods for monitoring and evaluating the effectiveness of the technologies used. This work will be of particular interest to professionals working in the oil industry, engineers and technologists, as well as researchers seeking to introduce innovative solutions into their practice. Students studying oil and gas will find useful materials in the book that will help them deepen their knowledge and prepare for future professional activities. The book can also attract the attention of economists and managers involved in the optimization of production processes and resource management. One of the key topics raised in the book is the need to move to more sustainable and environmentally friendly methods of oil production. The authors emphasize the importance of using chemical reagents that minimize negative environmental impact. In the face of global climate change and growing public pressure on oil companies, such approaches are becoming especially relevant. The book offers readers not only scientific data, but also practical recommendations for the introduction of environmentally friendly technologies. The style of the authors is distinguished by the clarity and accessibility of the presentation, which makes complex technical aspects understandable to a wide audience. M. A. Silin and his colleagues use examples from practice, which allows the reader to better understand how theoretical knowledge is applied in real-world conditions. The book includes many illustrations, graphs and tables, which makes the material more visual and easy to perceive. Among other well-known works of the authors are works on geology and hydrocarbon production technology, which are also popular among professionals and students. These publications complement and expand the understanding of the processes taking place in the bowels of the Earth, and technologies that help extract minerals from them. In conclusion, “Chemical reagents and technologies to improve oil recovery” is not just a book, but an important contribution to the development of oil science and practice. It will become an indispensable assistant for all who seek to improve the efficiency of oil production and the introduction of new technologies in their work. If you are looking for information about modern methods of increasing oil recovery, this book should definitely take a place on your shelf.
