Gazprom and RusGazDobycha expect construction of the first horizontal development well on Semakovskoye gas field in the Yamal-Nenets Autonomous Area of Russia to be complete by the end of June. The companies are moving forward with the project after reaching final investment decision for field development, Gazprom said in a release June 4.
The field, in the waters of Taz Bay and partly on land in the Taz Peninsula, is classified as large with recoverable gas reserves over 320 billion cu m.
During the preparatory stage, operator RusGazAlyans—formed in 2016 to assess development of three natural gas fields in the region—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) (OGJ Online, Sept. 6, 2016).
Development configuration 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 organizations.
As part of the first stage of pre-development, RusGazAlyans began development drilling. Construction is underway for the first horizontal development well with a vertical deviation of more than 2,000 m. The well is designed to have a measured depth of about 2,700 m, with a vertical depth of 830 m. Its construction, which includes geological studies, is expected to be finished by the end of June. Construction of the first six development wells is expected to be complete no later than first-quarter 2021.
Motorways and sites for production facilities are being built at the field, and logistical resources are being brought to the area.
The active phase of construction and installation will begin in this year’s second half with commercial field production expected to start in 2022 when 19 wells are expected to have been built. Extracted gas will be fed into Gazprom's gas transmission system.
Final investment decision on the development of Parusovoye and Severo-Parusovoye fields will be made at a later, unspecified date.
