RN-Vankor oil workers are introducing closed-cycle technologies in the north of the Krasnoyarsk Territory

RN-Vankor commissioned an early preliminary water release (EPWW) installation at the Vankor field.
New Russian equipment will make it possible this year to recycle over 5 million cubic meters of water using closed-cycle technology, increasing the environmental performance of production.
URPSV were developed and implemented by specialists from the corporate scientific institute in Ufa and engineers from RN-Vankor. This is the second complex of this kind at the Vankor field, installed near a group of well pads. Separation of produced water from well production, its purification from impurities and further injection into the formation is carried out in close proximity to the production site. This reduces the load on oil collection pipeline systems, pumping systems and oil treatment facilities.
The first installation of this type was launched in 2023 – as part of an innovative approach to introducing modular scalable solutions at RN-Vankor production facilities. Over two years, URPSV-1 separated more than 8 million cubic meters of formation water with its subsequent injection into the reservoir.
Compared to more powerful analogues, new early discharge units are autonomous and small-sized. For their operation, the hydraulic energy transmitted from the well stock is sufficient – the process of separating “free” water from the gas-liquid mixture occurs without the use of complex expensive equipment and additional energy costs.
In the next few years, it is planned to build installations of this type at the Vankorskoye, Tagulskoye and Lodochnoye fields.
RN-Vankor in its production activities implements the concept of a closed cycle and recycling of resources. From the very beginning of the exploitation of the fields of the Vankor cluster, after purification, formation water is sent for reuse in the system for maintaining reservoir pressure, which made it possible to completely abandon the intake of water for these purposes from external sources.
