Executives say the streamlining of the company's structure two years ago, merging independent Dutch and British units, has removed shackles from the company's performance, speeding up decision-making and helping efficient management of projects.
In the second quarter, Shell also benefited from having one of the biggest refining operations in the business, as crude processing margins hit near-record levels.
Earnings at Shell's downstream refining and fuel marketing division jumped 42%, with retail margins also firmer.
High oil prices, which averaged $63.92 per barrel in the quarter, underpinned the results.
Chief Executive van der Veer warned higher industry costs could keep pressure on profits as companies which provide products and services to the majors continue to raise prices.
This has helped some of the largest oil service companies, U.S.-based Schlumberger, France's Technip and Italy's Saipem, to this week report second quarter profit increases of around 50 percent compared to the same period in 2006.
However, Chief Financial Officer Peter Voser denied Shell's suppliers were taking advantage of a tight market.
"Their margins are not going up phenomenally," he told a news conference in London.
Van der Veer restated Shell's strategy of expanding into unconventional oil projects and projects which require complex infrastructure such as liquefied natural gas (LNG) plants, despite some investors worrying this move will hit margins.
Output from Shell's main unconventional oil source -- Canadian oil sands, tarry deposits from which crude can be extracted -- doubled in the second quarter and van der Veer said the company would start to break out profits for this unit separately in future.
