    OAO Gazprom is continuing predevelopment operations at 1.2-trillion cu m (tcm) Chayandinskoye natural gas field in Yakutia. Chayandinskoye is the primary resource base for the 38-billion cu m/year (bcmy) Power of Siberia gas trunkline to China.

    OAO Gazprom is continuing predevelopment operations at 1.2-trillion cu m (tcm) Chayandinskoye natural gas field in Yakutia. Chayandinskoye is the primary resource base for the 38-billion cu m/year (bcmy) Power of Siberia gas trunkline to China. As many as six compressor stations also are being built along the pipeline, increasing its ability to move Chayandinskoye gas. In 2020, Gazprom brought a Chavandinskoye gas pretreatment unit and more than 100 wells onstream and it plans to bring additional wells online in 2021.

    By late 2022, Kovyktinskoye field will be connected to Power of Siberia. Gazprom is building a pipeline section from this field to Chayandinskoye, with 261 out of 803.4 km welded, laid, and backfilled. Infrastructure under development at Kovyktinskoye includes foundation works and steel structure installation for Comprehensive Gas Treatment Unit No. 2 (CGTU-2). The site for CGTU-3 also is being prepared and development drilling continues.

    Start-up and commissioning is in progress on two production trains of the 42-bcmy Amur gas processing plant’s (GPP) first complex. Amur GPP will treat Kovyktinskoye production. Installation of process equipment is nearly finished on the third and fourth trains, and large equipment for gas separation is being prepared for assembly on the fifth and sixth trains. The project is 76.1% complete, according to Gazprom.

    A total of 333 km have been welded, laid, and backfilled as part expanding the 5.5-bcmy Sakhalin – Khabarovsk – Vladivostok gas pipeline between Komsomolsk-on-Amur and Khabarovsk. The work is nearing completion, Gazprom said.

    Development of the gas production on Yamal Peninsula also continues. At Bovanenkovskoye field, Gazprom plans to put additional compressors at gas production Site No. 3 and six gas wells into operation in 2021. At 2-tcm Kharasaveyskoye field, production wells are being drilled, and the construction of access roads for motor vehicles, sites for a CGTU and a booster compressor station, and a connection gas pipeline is in progress.
