The mechanism of the recovery for the heterogeneous heavy oil reservoirs

Key words: heavy oil, Yarega field, Usinsk field, the development works, oil recovery, steam-oil ratio, heterogeneous collector.

The article is devoted to the principles and methods of the unique heavy oil fields development in the Komi Republic. The main EOR method for heterogeneous fractured heavy oil reservoirs is the involvement of low-permeability reservoirs in the filtration process. A comprehensive analysis of the laboratory and field studies allowed to determine the main directions of the technologies development for the mentioned deposits. The technologies consider the features of the warm-up and oil recovery mechanism and the current state of these fields development to the maximum extent.
