Brothers turned Bridas, an oil services company founded by their father, into Argentina's second largest oil and gas company. In March 2010, China's National Overseas Oil Co.

In December, Bridas purchased from troubled British oil giant BP the 40% of oil and gas producer PanAmerican Energy it didn't already own, for $7.1 billion.
