Opec share of crude oil production
After oil slumped to around US$10/bbl, joint diplomacy achieved a gradual slowing of oil production by OPEC, Mexico and Norway. After prices slumped again in Nov. 2001, OPEC, Norway, Mexico, Russia, Oman and Angola agreed to cut production on 1 Jan. 2002 for 6 months. Saudi Arabia possesses around 18 per cent of the world’s proven petroleum reserves and ranks as the largest exporter of petroleum. The oil and gas sector accounts for about 50 per cent of gross domestic product, and about 70 per cent of export earnings.
