Gazprom continues field, processing development

Sept. 15, 2020
Gazprom is expanding production at Chayandinskoye field in Yakutia, eastern Russia. Chayandinskoye has B1+B2 reserves of 1.2 trillion cu m (tcm) natural gas and 61.6 million tonnes of crude oil and gas condensate.

Gazprom is expanding production at Chayandinskoye field in Yakutia, eastern Russia. Chayandinskoye has B1+B2 reserves of 1.2 trillion cu m (tcm) natural gas and 61.6 million tonnes of crude oil and gas condensate (OGJ Online, Apr. 27, 2020). In 2020 the company plans to bring 103 gas wells, a gas pretreatment unit (GPTU-2), and a membrane unit for helium concentrate extraction onstream. It will also complete the capacity increase at its operating comprehensive gas treatment unit (CGTU-3), which feeds gas into the 3,000-km, 38-billion cu m/year (bcmy) Power of Siberia pipeline.

The company’s predevelopment of Kovyktinskoye field in the Irkutsk region is also underway, with production drilling and site clearing for the construction of the first CGTU having started.

Construction and installation works are nearing completion at the Ivan Moskvitin compressor station (CS) on Power of Siberia, and the project's next stage is already being built. Preparatory activities are ongoing at the section of the pipeline route from Kovyktinskoye field to Chayandinskoye field.

Startup and commissioning continues on the first two production trains of the 42-bcmy Amur gas processing plant (OGJ Online, May 29, 2020). Gas separation equipment is being installed at the third and fourth production trains. At the fifth and sixth trains, the pouring of foundations is being completed and the assembly of pipe racks has started. Overall, the project is 66% complete.

Gazprom is making further efforts to expand the Sakhalin–Khabarovsk– Vladivostok gas pipeline between Komsomolsk-on-Amur and Khabarovsk. More than half of its linear part – 206 km – has been welded.

In the Nadym-Pur-Taz region, Gazprom is finishing its integrated project for liquid hydrocarbon transportation. As part of these activities it will put the Urengoy–Pur-Pe oil and condensate pipeline, a connecting condensate pipeline, the Urengoyskaya oil pumping station, and a condensate stabilization unit into service. These sites will transport condensate extracted from the Achimov deposits of Urengoyskoye field.

Gazprom also continues to develop its 32-field Yamal gas production center. In 2020, for instance, the company plans to connect 52 gas wells at 4.9-tcm Bovanenkovskoye field. At 2-tcm Kharasaveyskoye field, production wells are being drilled, and a connecting gas pipeline to Bovanenkovskoye is being welded and laid (OGJ Online, June 16, 2020).

The capacities of the northern gas transmission corridor are undergoing an expansion. The second workshops at the Chikshinskaya CS (Bovanenkovo–Ukhta 2 gas pipeline) and Novoprivodinskaya and Novoyubileynaya stations (Ukhta–Torzhok 2 gas pipeline) are being prepared to come onstream. Gas transmission line is being built at the section from Gryazovets to the under-construction Slavyanskaya CS.

Site clearing for Ust-Luga integrated complex for natural gas processing and liquefaction is also underway. Gazprom expects this complex to process 45 billion cu m/year of natural gas and produce 13 million tonnes/year (tpy) of LNG, as much as 3.8 million tpy of ethane, 2.4 million tpy of LPG, and 0.2 million tpy of pentane-hexane. Work also continues on construction of the LNG production, storage, and shipment complex near the Portovaya CS.
