Gazpromneft-Zapolyarye has completed the construction of an oil-gathering pipeline system, together with the installation of mobile oil treatment units, at its En-Yakhinskoye and Pestsovoye fields in the Yamalo-Nenets Autonomous Okrug, with this equipment having been delivered to the field prefabricated and ready-to-use. Using mobile solutions meant the extent and lead-times of construction and installation works (CIW) at these blocks — the development of which is complicated by the swampy territory in which they are located, as well as their remoteness from major logistics hubs — could be minimised.

All works — from delivery of equipment to start-up operations — took just three months: capital construction of similar production facilities would have taken more than a year. The total capacity of the mobile oil treatment units currently covers all of the fields’ processing needs and, in the event of higher hydrocarbon volumes in the future, can be increased by the addition of new units. Average daily production across both fields is currently approaching 3,000 tonnes.

Prefabricated equipment is expected to be used in building a central oil gathering plant and a compressor station (including a gas-engine power plant) at the Pestsovoye field in 2021. Peak production across both fields is expected to be reached in 2022, at two million tonnes of liquid hydrocarbons per year.

Gazprom Neft is now using mobile oil treatment units in preparing to develop its Yamburgskoye and Tazovskoye oil and gas condensate fields in the Yamalo-Nenets Autonomous Okrug, as well as in developing an oil-rim deposit at the Chayandinskoye oil and gas condensate field in Yakutia.

Gazpromneft-Zapolyarye is developing oil-rim deposits at the En-Yakhinskoye and Pestsovoye fields through long-term operatorship agreements with licence holder Gazprom Dobycha Urengoy LLC.
