The development of fields in the Arctic region requires advanced technological solutions both in the organization of production and in ensuring the environmental safety of projects and reducing environmental impact. The joint research programme will allow participants to learn about best practices and gain industry expertise to continuously improve environmental safety systems in the Arctic.

The Company takes annual measures to conserve and restore land resources, taking account of climatic, hydrological, soil, and vegetation conditions in the regions in which it operates.

The Company is implementing a target programme for the rehabilitation of contaminated lands and sludge pits and the processing of oil-contaminated waste. It includes an inventory of these areas and an assessment of the level of soil contamination in order to select and implement the most effective rehabilitation techniques. During the rehabilitation process, dead forests are cleared, oil-contaminated waste is collected, and technical and biological rehabilitation work is carried out. The company conducts an annual assessment of the quality of its measures to naturally rehabilitate land, which includes chemical and analytical monitoring.

The measures taken to protect Gazprom Neft land also include projects to improve the reliability of pipelines. In order to transport the pumped medium into the external environment with no loss, Gazprom Neft has implemented a pipeline integrity system, developed and constantly updated in accordance with Russian legislation and regulations. The system creates a uniform process for planning, implementing, and monitoring projects carried out in the Company's pipeline networks. Projects include measures to diagnose, inhibit, and monitor the corrosion rate, conduct maintenance and repair work, and replace pipelines. This work is designed to prevent accidents and leaks. It is conducted in accordance with technical regulations, instructions, flow charts, and maps that are developed in accordance with original design parameters, possible operation modes, design features of structures, and government and industry regulatory and technical documents.

The Company develops and implements cutting-edge technologies to improve the reliability of pipelines. In 2014, it completed the trial operation of a new diagnostic technology. This makes it possible to identify pipeline sections that are exposed to the highest risk which have not been adapted for internal diagnostics. Also in 2014, VID-219 equipment for internal diagnostics, which was developed at Gazprom Neft, was successfully tested. The device makes it possible to identify critical defects in small-diameter pipelines (100–200 mm). In addition, during the reporting year, Gazprom Neft-Noyabrskneftegas tested a new unmanned aerial vehicle that can fly 1,000 kilometres without refuelling. The drone, which is equipped with a camera and thermal imager, can monitor the status of pipelines that are hidden by snow.

Innovative technologies

Gazprom Neft is the first Russian oil and gas company to undertake a pilot project involving the use of innovative seismic exploration techniques, saving large forested areas that would otherwise have to be cut down. The new technology was tested in 2014 in Yamalo-Nenets Autonomous District. The test results showed that the method makes it possible to halve the level of deforestation compared with conventional seismic technologies and preserve 200 hectares of forest, or about 60,000 trees within an area of 400 square kilometres..

Technology development programme to prevent oil spills in the Arctic

Gazprom Neft is part of the Arctic Oil Spill Response Technology Joint Industry Programme implemented by the world’s largest oil and gas companies. Under the programme, companies conduct scientific research, studying the behaviour of oil under ice and testing dispersants (surfactant polymers used to eliminate oil spills) under conditions that simulate real ones, as well as the detection of spills in ice and in poor visibility.
