Map produced by the Research Department of the Foreign Office to accompany the document 'A Survey of the Oil Resources in the Middle East', dated 28 February 1945 (folios 18-30), showing all the known oilfields and concession areas of the Middle East along with neighbouring oilfields in Persia, Afghanistan and the Union of Soviet Socialist Republics (USSR).

The oilfields and concession areas are coloured in, with those in Iraq, Qatar, the Trucial Coast, Oman and Aden coloured orange; those in Saudi Arabia and Bahrain coloured green; Kuwait coloured purple; and Persia coloured pink. There are also two areas of Egypt which have been marked with striped coloured lines, the area west of Suez marked with red stripes, and an area east of Suez marked with purple stripes.

There are also two coloured lines marked on the map, running primarily through Saudi Arabia. The 'Violet Line' line marks the boundary of Ottoman territory and the 'Blue Line' the boundary of the Sanjaq of Najd. These lines are both marked according to the Anglo-Turkish Convention of 1913, which was unratified.

A key is located in the bottom right hand corner of the map and includes symbols for: producing oilfields, proven oilfields, pipelines, projected pipelines, existing refineries, and refineries under construction.
