This paper presents a profile of incremental oil production obtained at the Romashkinskoye field and other oil fields of the Republic of Tatarstan using different improved/enhanced oil recovery methods. It is shown that oil production increment due to standard techniques application (well drilling, EOR, reactivation of wells that have been out of production) has been reduced compared with that achieved using improved water flooding systems and other methods. The paper also discusses the main optimization trends for development systems at high levels of oil reserves depletion.
