Rosneft builds reserves, replaces 180pc of output

As a state company it enjoys privileged access to enormous offshore hydrocarbon reserves that are off limits to its private competitors. It plans to develop its Arctic reserves in alliance with ExxonMobil, Eni and Statoil.

Rosneft said on Tuesday that under Petroleum Resources Management System (PRMS) criteria, its proven hydrocarbon reserves - the largest among the world's listed oil companies - rose to 41.8 billion barrels of oil equivalent (boe) from 39.1 billion boe a year earlier.

"During the past five years, the company has been steadily replacing over 100 percent of its production by adding new reserves.

Resource base growth is one of the key elements of increasing shareholder value," Sechin said in a statement. Under the more stringent US Securities and Exchange Commission's (SEC) methodology, its proven hydrocarbon reserves rose to 33.0 billion boe as of Dec. 31, from 29.6 billion a year earlier.

As part of its buying spree, Rosneft last year acquired oil producer Taas-Yuryakh in East Siberia as well as Itera Oil and Gas Company. Despite its vast reserves, Rosneft is pencilling in annual production growth of only 1 percent until 2017.

Output growth should then accelerate to between 3 and 4 percent as new projects ramp up. Rosneft plans to increase production of natural gas to 100 billion cubic metres (bcm) by 2020 from around 40 bcm in 2013.

It has several projects that are due to come on line in the next couple of years.

It also wants to increase production at its major Vankor group of oilfield in East Siberia, where it expects to reach an output plateau of 500,000 barrels per day by 2019.
