Key words: Western Siberia, side track (ST), sidetracking, well profile, whipstock, milling bit, reduction in drilling costs.

Maintaining the productivity of marginal wells and recovery of inactive wells is one of the priority tasks for effective development of hydrocarbon fields. Presently, for these purposes, the technology of sidetracking from casing strings is widely used. The largest number of sidetracking operations in the Russian Federation, especially in the gas fields are conducted in Western Siberia. The article presents a brief history of the development of sidetracking technology, analyzes the results of the work, details the main aspects related to the application of the technology, and provides recommendations for the design of sidetracking using the example of a typical gas well on Cenomanian stratum in the Western Siberia fields.

Gas hydrates are a new kind of environmentally friendly source of energy with enormous reserves. The article compares the main differences in the methods of development of gas hydrates deposits and discusses the problems of their implementation. A new method of “liquefaction of the solid state” is proposed, offering a solution to the scientific and technical problems associated with the extraction of gas from gas hydrates in offshore non-diagenetic reservoirs of the South China Sea. Suggestions for advanced research and development in the field of gas production from hydrates are provided.
