Ulyanovsk oilmen changed the manufacturing scheme of the reservoir pressure maintenance system at Verkhozimskoye oilfield.

In the first place looping underlay (the second run) of the flow passage on formation water utilization was carried out, that permitted to increase the volume of the transported formation water. Flow separation at group pumping station by way of remanifolding of industrial pipe-lines (pressure pipe header) provided an opportunity to regulate the productivity of each pump and redistribute optimal pressure in the flow passage system.
Improvement of the reservoir pressure maintenance system allowed OAO “Ulyanovskneft” oilmen to create conditions for increasing the base oil production at Verkhozimskoye oilfield.
