FIRST LINE BUSINESS-ACCENT In the area of project implementation is the largest in the region number of representatives of indigenous minority peoples of the North – about 11 thousand people, half of whom lead a nomadic lifestyle. Gazpromneft-Yamal, provides financial assistance to the nomads who are in a difficult life situation, involves in various social projects and organization of air traffic and deliver food in remote areas. New approaches to the Arctic Applying of new technologies for the efficient and safe oil production in the permafrost is one of the key priorities of the company. On June, 2016, Gazprom Neft adopted a program "the development of fields in difficult climatic and geographical conditions" in the overall technological strategy of the unit of exploration and production. The objective of the program is to fix the best practices that are already applied in building on the various company projects, to select and test new technologies, and prepares model solutions for major building projects which will reduce the time searching for the right technology and to reduce the errors. Working in difficult climatic conditions is not news for oil and gas companies. Large deposits today, as a rule, are not located in the most accessible locations. Harsh climate, long distances to the nearest shelter, and problems with the transport infrastructure – all this can result to large difficulties for their settlement, and hence costly. As noted in the company, any extra ton of cargo becomes critical if you need to deliver thousands of kilometers on ice roads and incorrect logistics decisions can lead to a repeated growth of the already considerable expenses. Novy Port and Messoyakha are implemented in the permafrost zone. As explained by the specialists of Gazprom Neft: the soil here for thousands of years is in a frozen state, and the heat from the constructed facilities should not lead to thawing, otherwise the ground will "float" and begin to sink, damaging and destroying structures. To comply with temperature balance, the pipeline lay not in the ground and on supports. It is important that heat from the chimney, at which there is hot oil is not transferred into the ground. Therefore, the pipelines under the supports provided with stabilizers special tubes, collecting the heat from the soil into the environment. Buildings and tankers in these regions also erected on stilts and rose above the ground so that heat is not transmitted to the ground. As noted in the company, the cost of building the pipeline is affected by many different factors: FACTS 5.6 mln is the peak of extraction up to 2020 89.2 mln tons Gazprom plans to extract in 20<strong>17</strong> pipe material, design of supports, the thickness of the insulation layer, the use of electrical heating systems, selection of the optimal lengths of the pipeline. So in the construction of pressure pipeline on Messoyakha, the use of pipe material of higher strength class allowed to reduce the total cost of construction: decreased metal consumption, the weight of the pipe, thereby reducing the number of supports and to save on construction and installation works and delivery of the equipment. Gazprom Neft gives an example of saving on material in the framework of the project on the Novoportovskoe field. When laying pipelines on the multiple well platforms, usually used radial scheme where each well to measuring node is a separate pipe. But in permafrost regions they are located above ground on poles and it dramatically increases the consumption of the materials and the cost of the entire facility. “As a solution to problems of Novy Port was proposed and considered two-pipe system, consisting of a single tube of the collector and one test line. This scheme requires an increasing the number of valves, but it simplifies the site of the metering installation and significantly reduces the consumption of the whole system. In the future construction pads on permafrost will be carried out according to this scheme," said the company. One more direction of development of Arctic technologies is the use of the construction at oil production facilities finished modular blocks, allowing fast assembly in cold climate. According to the experts, currently, many pumping stations, canteens, administrative complexes, dormitories and many more are delivered as complete units with all necessary equipment. Using new approaches and technologies Gazprom Neft today is successfully developing the Russian Arctic. 18
