61% of the field area is located in Sharapov Shar Bay, Kara Sea
Gazprom specialists Dobycha Nadym, together with design institutes, are working on technical solutions for the development of the Kruzenshternskoye field. The company will test the development of offshore fields for the first time by creating artificial islands, the company’s press office said.
Taking into account a detailed technical and economic comparison of different options, the company will determine the optimal scheme for collecting, drying and transporting gas, the number of integrated gas processing units, the concept of developing a pressure boosting complex, degree of processing and logistics for the sale of liquid hydrocarbons.
Yamal’s Kruzenshternskoye field is considered an important resource base for ensuring the promising supply of gas to domestic and foreign markets. The maximum production volume of the field’s Cenomanian gas deposit is estimated at 33 billion m3 per year.
The deposit is characterized by the most difficult geocryological construction conditions. 61% of the area is located in the Sharapov Shar Bay of the Kara Sea. There is intense thermal abrasion along the entire length of the coast, the destruction of coastal permafrost rocks under the influence of waves. Multi-well platform construction technologies used in other fields on the Yamal Peninsula are not applicable to the large area. A team of scientists and engineers focused on finding the optimal design for the structures of the artificial islands.
“This will be the company’s first experience in offshore field development using land reclamation technologies. The work is extremely complex and serious, but this is not an obstacle for our team,” said Igor Melnikov, General Director of Gazprom Dobycha Nadym.
A total of 12 well pads are planned, including seven on artificial islands directly in the waters of the Kara Sea and in the floodplains. The production pit fund for the full development will be up to 208 units.
The development of a set of solutions, an important task at this stage, to ensure the full and uninterrupted operation of the facilities in the absence of ground transport infrastructure. For the first time in Gazprom’s practice, the Dobycha Nadym gas well clusters will be equipped with helipads to ensure year-round access, as well as the deployment of water transport.
Gazprom Dobycha Nadym is a 100% subsidiary of Gazprom. The company specializes in the production and treatment of gas and gas condensates. The first gas production enterprise in the north of Western Siberia was created for the development and operation of the Medvezhye oil and gas condensate field, as well as for the production of the Yubileynoye, Yamsoveyskoye and Bovanenkovskoye fields. The company holds a license to develop the Kharasaveyskoye gas condensate field, where development work is underway. Territory of operation: Nadymsky, Purovsky, Yamalsky districts of the Yamalo-Nenets Autonomous Okrug. Gazprom Dobycha Nadym is the main employer in Nadym and the village of Pangody with over 9,500 employees. The company has 13 gas fields in operation, 14 specialized branches. The annual volume of natural gas production is over 100 billion m3. The company has implemented an ISO 14001:2015 environmental management system.
