Samotlorneftegaz Achieves Economic Effect of over 1.5 Billion Roubles from Energy Saving Programme
Samomlorneftegaz's (part of Rosneft's production complex) energy conservation programme delivered total electricity savings of nearly 290 million kWh in 2025, equivalent to more than 1.5 billion roubles. To put that figure in context, a comparable volume of electricity powers Nizhnevartovsk — a city of more than 270,000 residents — for roughly two months.
The programme encompassed more than 4,000 individual initiatives across the company's production sites, spanning a broad range of areas from equipment modernisation to improvements in process management. The scale of the effort has delivered sustained results and established a foundation for further efficiency gains.
More than 56% of the total savings were achieved through optimisation of the mechanised production well stock. A central driver was the adoption of an advanced methodology for measuring oil content in produced reservoir fluid, which significantly improved measurement accuracy, enhanced production management and, as a result, reduced excess energy consumption.
A series of remedial and zonal isolation works carried out on the mechanised well stock generated savings of more than 11 million kWh.
As part of the modernisation of the company's reservoir pressure maintenance system, centrifugal sectional pumps were replaced at six cluster pumping stations. Commissioning of higher-efficiency units yielded electricity savings in excess of 8.9 million kWh.
A programme of replacements targeting electric submersible pump assemblies and asynchronous submersible electric motors reduced energy consumption by a combined 1.06 million kWh.
Particular emphasis was placed on digitalisation and greater transparency in production processes. A proprietary monitoring system for water-intake wells was developed and deployed to provide real-time oversight of the reservoir pressure maintenance network. The tool enables regular analysis of pumping equipment performance, allows operators to track changes in pressure and injection volumes, and facilitates timely adjustments to operating regimes through variable-frequency motor control.
For reference:
Samotlorneftegaz is one of Rosneft's key production assets, operating in the Khanty-Mansi Autonomous District - Yugra. The company develops the Samotlor field — the largest in Russia and one of the largest in the world — which has been in commercial production since 1969.
The enterprise's cumulative production stands more than 2.9 billion tonnes of oil and 420 billion cubic metres of gas.
