Experience of the use of physical and chemical methods of enhanced oil recovery of YuS2 layers of Surgutneftegs OJSC fields

Authors: A.P. Kondakov, S.V. Gusev, T.M. Surnova (Tyumen Branch of SurgutNIPIneft, RF, Tyumen)

Key words: low-permeability reservoirs, methods of enhanced oil recovery, physical and chemical methods, flow deviation technologies.

Factors complicating the effective development of YuS2 layers of Surgutneftegas OAO fields are shown. The main principles of effective application of physical and chemical methods of enhanced oil recovery are given. The volumes and the results of flow deviation technologies application at the fields of Surgutneftegas OJSC in 2009-2012 are presented.
