High-performance technological processes of reservoir pressure maintenance (RPM) are introduced at OAO TATNEFT to ensure enhanced crude oil recovery and maintain the production levels achieved. One of such technologies is inter-well pumping (IWP).

 

One of the main advantages of the technology is fast bringing of the areas where water flooding systems are not available into active development, thus increasing crude oil recovery by means of “native” formation water utilization.

 

Tube phase splitters are successfully used at NGDU Jalilneft, implementation and operation of which allows increasing the efficiency and expanding the applicability range of the inter-well pumping technology. Application of tube phase splitters reduces the volumes of produced water transportation towards the preliminary water dumping (removal) units without loss of oil production by expanding the limits of the profitable crude oil production range of the oil producing well stock and providing for a possibility of utilization of produced water as the injected agent.

 

The incremental crude oil production from responding wells is the result of crude oil recovery increasing and intensifying reserves displacement by injecting highly mineralized formation water into low-permeability and shale reservoirs. All this allows to reduce purchase volumes of fresh water for reservoir pressure maintenance, decrease the volumes of liquid pumping towards the preliminary water removal units and reduce the volume of water pipelines construction.
