OJSC Severneftegazprom today is a unique enterprise. The company is the fifth largest gas producer in the Gazprom Group and serves as an example of successful international cooperation in the field of gas production, combining promising Russian and foreign experience in both production and technology, and corporate governance. Shareholders of OJSC Severneftegazprom are the Russian gas giant OJSC Gazprom and the German concerns BASF SE (Wintershall Holding GmbH) and E.ON AG (E.ON Exploration & Production GmbH).



OJSC Severneftegazprom holds a license for geological exploration and production of hydrocarbons at the Yuzhno-Russkoye oil and gas condensate field in the YNAO. In 2012, in just four and a half years since the start of the field, the total cumulative gas production reached a symbolic 100 billion cubic meters. m, and annually at least 25 billion cubic meters are extracted from the subsoil of the Yuzhno-Russkoye field. m of gas. And this is just the beginning. In 2010, OJSC Severneftegazprom launched a unique project for Russia to extract hard-to-recover gas reserves from the Turonian deposits. Over the years, a number of companies made repeated attempts to develop this type of deposits, since their reserves are comparable to the traditionally developed Cenomanian deposits. And this is just the beginning. In 2010, OJSC Severneftegazprom launched a unique project for Russia to extract hard-to-recover gas reserves from the Turonian deposits. Over the years, a number of companies made repeated attempts to develop this type of deposits, since their reserves are comparable to the traditionally developed Cenomanian deposits. However, all projects failed - not enough technology. OJSC Severneftegazprom was the first enterprise in Russia to begin the successful development of the Turon. Together with leading Russian and Western specialists, the company developed and applied innovative technological solutions and manufactured unique equipment, which allowed them to drill and arrange a special well, get the first Turonian gas and send it to the Unified Gas Supply System of Russia.



Stanislav Tsygankov, General Director of OJSC Severneftegazprom, commented on the company's approach to the project: “Experiments on the production of Turonian gas in the past showed that its development by drilling traditional Cenomanian vertical wells is ineffective due to low production rates, and we had to look for other solutions to this problem . We went the other way and as a result we stopped drilling a two-hole subhorizontal well with a flat end.



Without exaggeration, this experience can be called unique both in terms of well design, and in relation to the special dual-purpose fountain valve and spider-elevator used for simultaneous descent into the well of two elevators of tubing (tubing - Ed.). Nobody has done anything like this before. ”




Ideas became a reality, and on April 7, 2012, in the presence of the heads of Gazprom and Gazprom export, at the Yuzhno-Russkoye field, a solemn ceremony of launching the first production well in Western Siberia to the Turonian gas reservoir took place. This day was a landmark not only for OJSC Severneftegazprom, but also for the entire Russian gas industry.



Alexander Medvedev, Deputy Chairman of the Gazprom Management Committee, Chairman of the Board of Directors of OAO Severneftegazprom, highly appreciated the results achieved by the company and noted during the ceremony that putting the well into the Turonian deposits into commercial operation “marked the beginning of a new stage in the development of the Russian gas industry assuming the development of hard-to-recover gas reserves", and that, “allowing new gas supplies to be provided in the future, the development of the Turonian deposits, initiated by OJSC Severneftegazprom, helps to solve the most important goal of Gazprom as a gas supplier in the new gas transmission project - ensuring stability and continuity of supplies to Europe” .



The development of the Yuzhno-Russkoye field is of strategic nature for the industry, because its gas is one of the main resource bases for deliveries via the Nord Stream gas pipeline. This factor is due to the company's desire to ensure a stable for a long time gas production volume due to the introduction of Turonian deposits into the development in the future. It is assumed that the increase in annual production after the start of industrial development of hard-to-recover reserves may reach 5–8 billion cubic meters. m per year.



Today, OJSC Severneftegazprom does not stop at what has been achieved and continues to improve. Together with Russian, foreign partners and shareholders, the company is introducing new technologies, looking for optimal technical solutions that bring effect not only from an economic, but also from an environmental point of view. So, at present, OJSC Severneftegazprom is implementing a project to introduce an innovative installation for the disposal of industrial effluents, and is also working on a project for the disposal of flue gases from gas pumping plants.

This project involves the generation of electricity through the heat of waste gases, and its implementation will be able to make a significant contribution to the protection of the environment.



Much attention is paid to social policy: OJSC Severneftegazprom participates in the implementation of social and charitable projects, provides comprehensive support to the regions of its presence - Krasnoselkupsky and Purovsky districts of the Yamal-Nenets Autonomous District, Novy Urengoy. In 2012 alone, Severneftegazprom allocated over 50 million rubles to support them.



OJSC Severneftegazprom is a vivid example of successful international cooperation between Gazprom and European companies. Here innovations and traditions, efficiency and adventurism, confidence and riskiness are united. But the main definitions that can be applied to the work of a company are success and result. And they were not long in coming!
