The field, which is located in the waters of Taz Bay and partly on land in the Taz Peninsula, is classified as large: its recoverable gas reserves exceed 320 billion m3.
During the preparatory stage, the project operator – RusGazAlyans (established on a parity basis by the Gazprom Group and RusGazDobycha) – carried out a set of design and survey works, drew up the design documentation, and obtained permits from governmental authorities to start construction and installation operations as part of the first stage of field pre-development (land). The configuration of the development project is fully defined, including the priorities for the construction and commissioning of production and transmission facilities, the procedure for recording and purchasing extracted gas, and the ongoing efforts for attracting project financing from Russian credit organisations.
As part of the first stage of pre-development, RusGazAlyans commenced development drilling. Construction is underway for the first horizontal development well with a vertical deviation of more than 2000 m. The well is designed to have a measured depth of about 2700 m, with a vertical depth of 830 m. Its construction, which includes geological studies, is expected to be finished by the end of this June. It is planned to complete the construction of the first six development wells by no later than 1Q21.
In addition, motorways and sites for production facilities are being built at the field, and logistical resources are being brought to the area.
According to the project schedule, the active phase of construction and installation is going to begin in the second half of 2020.
Commercial production at the Semakovskoye field is slated to start in 2022. By that time, 19 wells will be built there. The extracted gas will be fed into Gazprom's gas transmission system.
The FID on the development of the Parusovoye and Severo-Parusovoye fields will be made later.
