HOUSTON, Sept 14 (Reuters) - Saudi Arabia's oil productionand exports have been disrupted bydrone attacks on two major oil facilities run by state-ownedcompany Aramco, including the world's biggest petroleumprocessing facility.
Two sources close to the matter said 5 million barrels perday of crude production had been impacted -- close to half ofthe kingdom's output or 5% of global oil supply.
The pre-dawn drone attack by Yemen's Iran-aligned Houthigroup set off several fires, although the kingdom, the world'slargest oil exporter, later said these were brought undercontrol.
State television said exports were continuing, howeverAramco has yet to comment since the assault. The authoritieshave not said whether oil production or exports were affected.
Here are key facts about the historically secretive oilcompany, including details released this year of its financesand operations.

OIL PRODUCTION
The company produced 10.3 million barrels per day (bpd) ofcrude last year, touting the lowest cost in the world to producecrude, at $2.8 a barrel, according company documents. It alsoproduced 1.1 million barrels of natural gas liquids and 8.9billion standard cubic feet per day of natural gas.
OIL EXPORTS
Almost three-quarters of Aramco's crude exports, about 5.2million bpd, were delivered to customers in Asia last year,where it believes demand will grow faster than elsewhere in theworld. Its Asian buyers include China, India, South Korea, Japanand Taiwan. Its crude deliveries to North America reached morethan 1 million bpd last year; to Europe, 864,000 bpd.
