In 1950, the Middle East was supplying 18.3% of the world's petroleum outside of the USSR and it's client states. As a whole region, it surpasses every other region in total export of petroleum, crude, and refined oil combined. As of 1950, half of the world's oil reserves remain within the Middle East. The two largest pipelines are the Trans-Arabian pipeline which is in construction as of now and will be finished in 1950 that carries 315,000 bpd (barrels per day) or 15.5 million tons of oil per year. The other is the Kirkuk-Haifa pipeline which has a capacity of 275,000 bpd or 13.5 million tons of oil per year. The Trans-Arabian pipeline begins in Qaisumah, Saudi Arabia along the Persian Gulf and will end in Haifa as well. The Trans-Arabian pipeline is also the only of the two that actively operates at max capacity.

In 1950, according to a BP report, the world oil production was ten million barrels per day. In addition to the two largest pipelines, there's the A-B pipeline in Bahrain that connects to Saudi Arabia that has a capacity of 30,000 bpd or 1,512,000 tons of crude oil a year. Iran's oil production totals at 647,500 bpd or 32,256,000 tons of crude oil a year. Kuwait totals at 347,000 bpd or 17,280,000 million tons of crude oil a year. Iraq equals 130,000 bpd or 6,480,000 tons of crude oil a year, equaling about a third of the total possible max capacity of the Kirkuk-Haifa pipeline. However, 2,000,000 of that crude oil goes to Tripoli due to an agreement between the Iraqis, British, and French and therefore the Kirkuk-Haifa pipeline is even farther from acting at max capacity, making it unique compared to most pipelines which acted at max capacity in 1950. Egypt produces 47,000 bpd or 2,340,000 tons of crude oil a year. Finally, Qatar produces 33,000 bpd or 1,632,000 tons of crude oil a year.

In terms of refined oil, for simplicity's sake will focus on an aggregate total of refined products instead of each individual product type. Going from largest to smallest, Iran produces 177,875,000 barrels of refined products. Bahrain, primarily with the Sitra refinery, produces 56,059,000 barrels of refined products. Saudi Arabia produces 35,577,000 barrels of refined products. Egypt produces 14,511,000 barrels of refined products. Kuwait produces 7,599,000 barrels of refined products.
