For the first time in its illustrious history, Ukrnafta has harnessed cutting-edge technology to optimize reservoir pressure maintenance systems, resulting in a remarkable 17% surge in oil production at a pilot site within one of the company’s western fields.
 
In a bid to enhance oil recovery, the company employed a flow-deflecting technology integrated with cross-linked polymer systems.

In February 2024, at a field located in the Ivano-Frankivsk region, the Oil Recovery Enhancement Division of the Field Development Department pioneered the use of flow-deviating technology with cross-linked polymer systems. This marked a significant stride in optimizing the reservoir pressure maintenance system.
 
The process entails the injection of a polymeric composition into the injection well, effectively blocking the washed-out zones from injection to production wells and engaging previously untapped areas of the reservoir.
 
A total of 130 cubic meters of cross-linked polymer composition was pumped into the injection well.
 
Over a span of two months, specialists from the Oil Recovery Enhancement Division of the Field Development Department, Oil and Gas Production Department, Research and Design Institute, and Oilfield Services Department diligently monitored and recorded a decrease in water content and an uptick in the production rate in the affected production wells.
 
The cumulative increase in oil flow rate for this research object was an impressive 16.9%.
 
In a strategic move to boost oil production, Ukrnafta plans to implement this technology across all its structural units’ fields. The sites have already been earmarked, and the necessary reagents procured.
