JSC Arcticgas, a joint enterprise between Gazprom Neft and NOVATEK, holds exploration and production (E&P) licenses for the Samburgskoye license area, as well as licenses for geological prospecting and hydrocarbon production within the Yevo-Yakhinskoye, Yaro-Yakhinskoye and Severo-Tchaselskoye areas. The company’s proven reserves (PRMS standards) as at 31 December 2014 amount to 695 billion cubic metres of natural gas and 127 million tonnes of liquid hydrocarbons.

The first phase of the Samburgskoye field (part of the Samburgskoye license area) was brought into production in April 2012 and the second in December 2012, with the third commissioned in September 2014. Total capacity at the field is estimated at seven billion cubic metres of gas and 900,000 tonnes of gas condensate per year.

The first phase of the Urengoyskoye field (part of the Samburgskoye license area) was brought into production in April 2014 and the second in December, with the field going into full commercial production in March 2015. Total capacity at the field is estimated at 13 billion cubic metres of natural gas and 4.7 million tonnes of de-ethanized gas condensate per year.

The Yaro-Yakhinskoye field was brought into production in early April 2015. Production at this field is shortly expected to reach projected levels of around 7.7 billion cubic metres of natural gas and 1.3 million tonnes of de-ethanized gas condensate per year.

The Achimov oil and gas formation is one of the most complex development prospects in Western Siberia. The Achimov deposits lie at a depth of around 4,000 metres, and have a far more complex structure in comparison with the Senomansky (which lie at a depth of 1,100–1,700 metres) and the Valanzhinsky formations (which lie at a depth of 1,700–3,200 metres). In addition to this, the Achimov deposits are subject to abnormally complex high reservoir pressure (of more than 600 standard atmospheres), and are further complicated by lithological and tectonic framework, characterised by the highly variable condition of the deposits.
