Ulyanovsk. OAO Ulyanovskneft, AO NK RussNeft subsidiary, performs activities for development of the system of reservoir pressure maintenance at the fields.
In particular, wells No. 31, No. 44, No. 30 of Zapadnoye, Kudryashovskoye, Mordovoozerskoye fields accordingly were included in the reservoir pressure maintenance stock in 2015. Currently the company performs activities to reach 100% injection ratio within the area of these facilities.

The Ulyanovsk oilmen intend to restore the energy potential of formations and stabilize the production output at the current well stock by performing regular injectivity profile strengthening activities. The reservoir pressure maintenance stock includes 16 wells in total.
