Ulyanovskneft maintains reservoir pressure
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.
Apart from that, conversion of the wells into the reservoir pressure maintenance stock in 2014 proved to be efficient. Thus, wells No. 17, No. 28, No. 30 of Zapadnoye field add jointly 30 tons per day to production of the producing wells and well No. 32 of Varvarovskoye field adds 10 tons per day to production of the surrounding producing wells.
Development of the reservoir pressure maintenance system is a strategic target of the company. In 2015 the company intends to convert at least 3 wells into reservoir pressure maintenance wells. 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.
