Petroleum Development Oman
Petroleum Development Oman is the foremost exploration and production company in the Sultanate. It accounts for more than 70% of the country's crude-oil production and nearly all of its natural-gas supply. The Company is owned by the Government of Oman (which has a 60% interest), Royal Dutch Shell (which has a 34% interest), Total (which has a 4% interest) and Partex (which has a 2% interest). The first economic find of oil was made in 1962, and the first consignment of oil was exported in 1967.
