Net profit in October-December was 5 billion rubles ($213 million), a 26.7% rise on the third quarter, which the company said was due to higher earnings caused by an increase in prices and sales.
Novatek's natural gas output declined 0.7% in 2007 on the previous year, to 28.5 billion cubic meters.

Established in 1994, Novatek handles the prospecting, production and refining of gas and liquid hydrocarbons.

The region accounts for over 90% of Russian natural gas output and around 20% of global gas production.
