Ukrnafta targets 100,000 tonnes oil boost via reservoir pressure support

JSC Ukrnafta is working on reservoir pressure maintenance systems to boost oil production at its fields, the company announced on Tuesday. As fields age and oil recovery rates decrease, reservoir pressure naturally drops. Ukrnafta's reservoir energy management technologies allow for better control of this pressure decline by injecting water, gas, and other environmentally safe substances.

This maintains reservoir energy, improves oil displacement, and boosts oil recovery rates. Currently, Ukrnafta is applying RPM technologies at 19 of its fields. Over the past four years, the company analyzed 16 fields and installed modern equipment at five, using flow-diverting compounds in five injection wells across three fields.

This optimization led to an additional 7,200 metric tons of oil produced. For the next stage, Ukrnafta plans to implement three key projects by 2030. These include establishing an RPM system at a promising field, expanding an existing system, and introducing polymer flooding at an operating site. The combined effect of these projects could result in approximately 100,000 metric tons of additional oil recovered over five years.

Ukrnafta is Ukraine's largest oil producer, with operations covering exploration, production, and services. The company produces hydrocarbons from 1,789 oil wells and 167 gas wells. Its shareholders include Naftogaz Ukrainy and the Ministry of Defense. Ukrnafta is undergoing a large-scale business transformation under state management, having ranked first in the extractive industry in 2025 with UAH 99.6 billion in revenue.
