Our subsidiaries and joint ventures are producing wet gas – a mixture of natural gas and gas condensate. After being separated and de-ethanized at the field the unstable (de-ethanized) gas condensate is delivered via a system of condensate pipelines owned and operated by the Company for further stabilization at our Purovsky Plant located in the YNAO in close proximity to the East-Tarkosalinskoye field.
The Purovsky Plant is the central element in our production value chain that provides us complete operational control over our processing needs and access to higher yielding marketing channels for our stable gas condensate. The Purovsky Plant produces stable gas condensate and light hydrocarbons after processing our unstable gas condensate.
As a result of launches of the Termokarstovoye and the Yaro-Yakhinskoye fields, in June 2015 the Purovsky plant reached full utilization of its processing capacities amounting to more than 12 mmt of unstable gas condensate on an annualized basis. The Purovsky Plant’s processing capacity matches the overall gas condensate production capacity of the Company’s fields in operation as of the second half of 2015.
During 2015, the de-ethanized gas condensate processing volumes at the Purovsky Plant increased by 82.1% to 12,021 mt. The structure of this output included 9,664 mt of stable gas condensate, 2,228 mt of light hydrocarbons and LPG and 11 mt of regenerated methanol. Our feedstock composition changed following the launches of new fields in 2015 resulting in a higher share of stable gas condensate in the total output of the plant, which increased from 78.5% in 2014 to 81.2% in the reporting year.
The Purovsky Plant is connected via its own railway line to the Russian rail network at the Limbey rail station. Subsequent to the launch of the Ust-Luga Complex in 2013, most of the stable gas condensate volumes produced at the Purovsky Plant are delivered by rail to Ust-Luga for further processing or transhipment to exports, with most of the remaining small volume of stable gas condensate sold directly from the plant to the domestic market. Commencing from the second quarter 2014 all of the light hydrocarbon volumes (feedstock for LPG production) produced at the plant are delivered by pipeline to SIBUR’s Tobolsk Petrochemical Complex for further processing.
