Since its helicopters began operating in oil-and-gas in the 1960s, Airbus Helicopters has logged 10 million flight hours in the sector. The first two regions are the Americas (4.1 million) and Europe (3.3 million), followed by Asia (1.82 million), Africa (557,000) and Oceania (216,000). Of the estimated 2,300 rotorcraft used in oil-and-gas missions today, approximately 25 percent are produced by Airbus Helicopters, the manufacturer estimates. The Super Puma series is the frontrunner, accounting for approximately one third of the 10 million flight hours.
