Annotation:

Most fields in the Volga-Ural oil- and gas-bearing province are in the final stages of their development. This stage is characterized by a rapid decline of average daily flow rates, a decline of hydrocarbon production and the formation of poorly soluble compounds in the near-well bottom zone, requiring the prompt implementation of well control methods for production and injection wells. Many fields of the region under study contain hard-to-recover reserves and high-viscosous oils, where standard enhanced oil recovery methods are not always effective. One of the most well-known methods for enhancing wells performance in such challenging geological conditions is in-situ combustion, which has already proven its highly effectiveness when working with high-viscous oils. The authors of the article discuss the application of this methodology for increasing the production of low flow-rate wells at the Yugomashevskoye field.
