Oil giant Royal Dutch Shell has reported a 77% jump in second-quarter profit, thanks to higher energy prices.
Shell's profit for the three months to June came in at $8bn (£4.9bn) on a current cost of supplies basis, up from $4.5bn in the same period last year.
Though oil and gas production was 2% lower than the same quarter in 2010, the company said it had benefited from asset sales in the first half of 2011.
Earlier this week, rival BP announced second-quarter profits of $5.3bn.
New projects
The price of oil is much higher now than it was a year ago, in part inflated by political unrest in oil-producing countries such as Libya.
Twelve months ago, US light sweet crude oil was trading at about $78 a barrel. It is currently trading at about $97 a barrel, having topped $110 at the end of April.
Shell also said it had sold $4bn of non-core assets in the first six months of the year, which was a "key driver" to reducing costs and improving its operating performance.
However, like BP, Shell's production was down in the second quarter year-on-year, due to field sales and warm weather which hit European gas demand.
But the company said it had started three large-scale projects this year that would add to its oil production by over 400,000 barrels per day.
These are a Canadian oil sands venture and two gas plants in Qatar, in which it has invested $30bn.
"We have made important progress with new production in 2011, and the ramp-up of our new projects should drive our financial performance in the coming quarters," said Shell chief executive Peter Voser.
