The book “Orenburg tectonic knot: geological structure and oil and gas content” is a unique publication created by a team of authors that immerses the reader in the world of geology and the oil and gas industry. This is not just a scientific work, but a real encyclopedia of knowledge about the most important geological formation of Russia, which plays a key role in providing the country with energy resources. The Orenburg tectonic node is a complex structure that has been formed over millions of years, and it is in this region that significant hydrocarbon reserves are concentrated. The book explores in detail the geological structure of the node, its tectonic features and, most importantly, the oil and gas content. The authors, with in-depth knowledge of geology, geophysics and oil and gas exploration, share the results of many years of research that will help the reader understand how these riches of nature were formed and how they can be used in the future. This book will be of interest not only to professional geologists and specialists in the oil and gas industry, but also to students studying geological sciences, as well as to all those who are interested in natural resources and their use. It can be an indispensable tool for graduate students and young scientists seeking to deepen their knowledge of geological processes and their impact on the economy of the country. The themes raised in the book are diverse and multi-faceted. The authors consider not only the geological aspects, but also the economic, environmental and social consequences of the development of oil and gas fields. They ask questions of sustainable development, the need to comply with environmental norms and regulations, as well as the importance of a scientific approach to the exploration and production of hydrocarbons. These issues are becoming increasingly relevant in the face of global climate change and the growing need for clean and safe energy sources. The style of the authors is distinguished by scientific rigor and accessibility of the presentation, which makes the book understandable even for an unprepared reader. Each section is accompanied by illustrations, graphs and maps that help to visualize complex geological processes and make the material more visual. The book also includes an extensive list of literature, which allows interested readers to delve deeper into the study of the topic. The team of authors who worked on this book consists of recognized experts in the field of geology and oil and gas exploration, which gives the work special value. Their previous publications and research have already established themselves in the scientific community, and this book will not be an exception. It can become a basis for further research and discussion, as well as a source of inspiration for new ideas in the field of geology and energy. "Orenburg tectonic node: geological structure and oil and gas" is not just a book, but an important contribution to the understanding of geological processes and their impact on the economy and the environment. It will be a useful resource for all who seek to understand how natural resources shape our future and what challenges humanity faces in this area. If you are interested in geology, the oil and gas industry or just want to expand your horizons, this book should definitely take a place on your shelf.
