Gazpromneft-Zapolyarye (a subsidiary of Gazprom Neft) will begin development of the Neocom-Jurassic deposits of the Bovanenkovo oil and gas condensate field and the Kharasavey gas and condensate field on the Yamal Peninsula, as well as the Achimov deposits * and the oil rims of the Urengoy oil and gas condensate field in the Nadym oil field of the Nadym-Odymnoye oil and gas condensate field of Nadym.
Projects will be implemented on the basis of long-term risky operator contracts ** with license holders, Gazprom dobycha Nadym *** and Gazprom dobycha Urengoy ****, which develop overlying layers of fields. When developing new assets, Gazprom Neft uses its experience and competencies in the development of the Achimov stratum and oil rims. Implementation of the projects will be carried out in cooperation with PJSC Gazprom at the main stages in order to unconditionally achieve the established key performance indicators.
In 2020, Gazpromneft-Zapolyarye will equip one cluster site at the Bovanenkovskoye and Kharasaveyskoye fields and drill two wells to remove geological uncertainties. In total, within the framework of the project, the enterprise will build more than 250 high-tech wells. The commencement of the industrial development of the Neocom-Jurassic deposits of the Bovanenkovsky and Kharasaveysky deposits is planned for 2025 and 2026. The maximum annual level of production on assets will be reached by 2031 and will amount to more than 38 billion cubic meters of gas and up to 4.1 million tons of condensate. Currently, preparatory work and arrangement of cluster sites are underway at the fields.
In 2020, at the Urengoyskoye oil and gas condensate field, 2 production gas condensate wells will be drilled. The data obtained with their help will help to clarify the geological features of the structure of the Achimov deposits of section 3A of the field. In total, Gazpromneft-Zapolyarye plans to drill 32 high-tech horizontal wells on this asset. Peak production is expected in 2024. It will amount to 5 billion cubic meters of gas and up to 1.5 million tons of gas condensate.
The second phase of the project will be the development of the Valanginian deposits of oil rims of the Urengoy oil and gas condensate field. Now the company is preparing a re-testing program for exploratory wells. Its results will be used in choosing the concept of developing the Neocomian deposit.
“The development of the Neocom-Jurassic, Achimov deposits and oil rims of the Bovanenkovo, Kharasaveysk and Urengoy fields is among the strategic rates of Gazprom Neft. They are unique in their scale and complexity. Moreover, each project has a long investment cycle, so we are starting preparations for their development now. In the horizon of 5 to 10 years, it is these assets that will become the basis for the development of the company in the north of Yamal and one of the key sources of our production in the Arctic. The colossal resource potential of this region in many respects remains unsolved, since work in the Arctic is always fraught with a number of organizational, logistical and technological challenges. Gazprom Neft’s successful experience in developing autonomous Arctic fields,Vadim YakovlevDeputy General Director for Production and Exploration, Gazprom Neft
* Gazpromneft-Zapolyarye is developing the Achimov deposits of block 3A of the Urengkoye oil and gas condensate field.
** The scheme of long-term risky operator relations allows Gazprom Neft to operate on Gazprom assets on conditions similar to owning a license, to consolidate reserves, production and financial results from field development. The peculiarity of the working mechanism of this form of the contract is that Gazprom Neft invests its own funds in exploration and construction of infrastructure.
By working on the basis of long-term risky operator contracts, the company has significantly expanded its portfolio of projects, having begun to develop oil rims, Achimov deposits and Neocom-Jurassic gas and gas condensate deposits. Currently, Gazpromneft-Zapolyarye is developing nine fields licensed by Gazprom and its subsidiaries: Pestsovoye, Yen-Yakhinskoye, Zapadno-Tarkosalinskoye, Chayandinskoye, Yamburgskoye, Orenburgskoye, Urengoyskoye, Kharasaveyskoye and Bovanenkovskoye.
*** Gazprom dobycha Nadym LLC is a 100% subsidiary of PJSC Gazprom. The main activities: production and preparation of gas and gas condensate.
The first gas producing company in the north of Western Siberia. Created for the development and operation of the Bear oil and gas condensate field. Today it also conducts production at the Yubileynoye, Yamsoveyskoye and Bovanenkovskoye fields. The company holds a license for the development of the Kharasavey gas condensate field, where work is underway on the development.
Territory of activity: Nadym, Purovsky, Yamal regions of the Yamalo-Nenets Autonomous Okrug. It is a city-forming enterprise for the city of Nadym and p. Pangody. The team has more than 10 thousand employees.
The enterprise includes 13 operating gas fields, 15 specialized branches. The annual volume of natural gas production is more than 100 billion cubic meters. m
The company has implemented an environmental management system ISO 14001: 2015.
**** Gazprom dobycha Urengoy LLC is a wholly- owned subsidiary of PJSC Gazprom, created to develop the Urengoy oil and gas condensate field. The production complex includes: 22 integrated gas treatment plants, two oil fields, 20 booster compressor stations, five gas cooling stations, over 2,800 wells, two associated petroleum gas utilization compressor stations and a condensate pumping station.
The company employs more than 12 thousand people. The head office is located in Novy Urengoy.
An oil rim is a part of an oil and gas or oil and gas condensate reservoir in which gas occupies a substantially larger volume than oil. In fact, this is a thin layer of oil between a much larger gas cap and an aquifer. The effective development of such geologically complex resources requires the introduction of new technological solutions for drilling complex wells, the search for methods of lifting liquids with a high gas content and high precision integrated design.
Achimov deposits are strata located in the lower part of the Cretaceous sediments almost directly above the Bazhenov formation (a group of rocks in Western Siberia occurring at depths of two to three to four kilometers). Achimov deposits are widespread in the central zone of the West Siberian basin, the most powerful strata are identified in the Nadym and Purovsky districts of the Yamalo-Nenets Autonomous Area. Achimov deposits are characterized by a complex geological structure, which requires the use of technologically sophisticated methods in the development of these reserves.
Neocom-Jurassic gas and gas condensate deposits are deep formations of the Kharasavey and Bovanenkovo deposits, belonging to the lower part of the Melova and Jurassic systems, located at depths from 1600 to 3300 meters and characterized by difficult geological conditions: high reservoir pressure and often low reservoir permeability.
The largest gas field on the Yamal Peninsula. Initial gas reserves are 4.9 trillion cubic meters. m. Gazprom began production here in 2012. The projected level of gas production at the Bovanenkovo field is 115 billion cubic meters. m per year. In the future, up to 140 billion cubic meters. m per year due to the connection of Neocomian-Jurassic deposits.
The field is located on the Yamal Peninsula north of the Bovanenkovskoye field, mainly on the land of the peninsula and partially in the Kara Sea. By the size of gas reserves it belongs to the unique category – 2 trillion cubic meters. In March 2019, Gazprom began the full-scale development of the Cenomanian-Aptian gas deposits of the Kharasaveyskoye field.
The Urengoyskoye field is the largest oil and gas condensate field in Russia; it is classified as super-giant in terms of hydrocarbon reserves. Initial gas reserves exceeded ten trillion cubic meters of gas. The field was discovered in June 1966. Gas production began in 1978. In 1987, commercial exploitation of oil wells began here. Since 2008, gas and condensate have been extracted from Achimov deposits.
