MOSCOW (Reuters) - Russia's largest oil producer Rosneft ROSN.MM will buy around 6 million tonnes of oil worth over $2 billion from domestic producers next year, according to an announcement on a state-owned website for purchases of companies' needs.

According to the website, Rosneft will buy 5.14 million tonnes of oil worth 132.5 billion roubles ($1.9 billion) from Gazprom Neft SIBN.MM.

The price works out at around $46 per barrel compared to a current price of Russian Urals crude blend of $51 per barrel.

Rosneft’s total oil production is seen at 241 million tonnes of oil (4.82 million barrels per day) next year.

Rosneft has not disclosed its oil purchases for the whole 2018.

Rosneft said, in an emailed response to a request for a comment, that the purchases will allow it to cut transportation costs and are “usual practice in the oil industry”.
