The Omsk branch of GlavGosEkspertiza of Russia considered the re-submitted project documentation and the results of engineering surveys for arrangement of the Valanginian deposit of the East-Urengoyskoye field. Positive conclusions were issued as a result of the state expert examination.
Development of the Valanginian deposit within the East-Urengoyskoye field in Yamal-Nenets Autonomous Okrug was started in 2015. The license for the subsoil area belongs to Rospan International, a subsidiary of Rosneft. The recoverable reserves of the oil and gas bearing deposit multi-layered in structure are estimated at 19 million tonnes of oil and condensate, as well as 98 milliard cubic meters of gas, as the press center of GlavGosEkspertiza of Russia reports.
The project documentation provides for arrangement of the reservoir BU16 (1-4) of the Valanginian deposit for the time of pilot operation, arrangement of two production wells at cluster site No. 4-01, as well as construction of an oil treatment unit.
Constructions, placement of which is stipulated within arrangement of the cluster of wells, are purposed for extraction, collection and measurement of product consumption of the production wells with defining of production rate, flow of paraffin inhibitor. Constructions included in the oil treatment unit for the time of pilot operation are purposed for separation of hydrocarbon raw materials and reservoir waters of the production wells. The capacity of the unit is calculated from the condition on ensuring of reception of the maximum production amounts from the cluster of wells on liquid, oil, reservoir water and gas.
The operations will be held in two stages. At the first stage engineering preparation of cluster of wells No.4-01 and technological tying in well R-911 will be performed, as well as the oil treatment unit will be built. Technological tying in well No.4-01-02 and its connection to the oil treatment unit will be fulfilled at the second stage. At the same time, construction of wells is not considered in the project documentation.
On the territory specialists will lay internal roads and will equip the site for firefighting equipment at the entrance to the cluster. The external access to the cluster of wells and the oil treatment unit will be provided on the existing motor road.
