Ten years sounds a bit high but basically believable for ANWR. Aramco can move a lot faster because it's basically an agent of a sovereign state acting in its own territory. So none of that messy applying for permits for every little increment of the program. Plus the Saudi Eastern Province is easily accessible year-round, whereas in ANWR you're operating in a swamp in the summer and in a pitch-black Arctic hell in winter. Plus the ANWR coastal plain is a lot more environmentally complex than the Arabian desert, and contrary to what you may have heard, most oil companies DO take the time and effort to keep damage to a minimum; it's better for business in the long run.
