The Anglo-Persian Oil Company (APOC; Persian: شرکت نفت ایران و انگلیس) was a British company founded in 1909 following the discovery of a large oil field in Masjed Soleiman, Persia (Iran). The British government purchased 51% of the company in 1914, gaining a controlling number of shares, effectively nationalizing the company. It was the first company to extract petroleum from Iran. In 1935 APOC was renamed the Anglo-Iranian Oil Company (AIOC) when Reza Shah formally asked foreign countries to refer to Persia by its endonym Iran.2

The story

Creation of APOC

On 14 April 1909, Burmah Oil created the Anglo-Persian Oil Company (APOC) as a subsidiary and also sold shares to the public.

Volume production of Persian oil products eventually started in 1913 from a refinery built at Abadan, for its first 50 years the largest oil refinery in the world (see Abadan Refinery). In 1913, shortly before World War I, APOC managers negotiated with a new customer, Winston Churchill, who was then First Lord of the Admiralty. Churchill, as a part of a three-year expansion program, sought to modernise Britain's Royal Navy by abandoning the use of coal-fired steamships and adopting oil as fuel for its ships instead. Although Britain had large reserves of coal, oil had the advantage of greater energy density, allowing a longer steaming range for a ship for the same bunker capacity. Furthermore, Churchill wanted to free Britain from its reliance on the Standard Oil and Shell oil companies. In exchange for secure oil supplies for its ships, the British government injected new capital into the company and, in doing so, acquired a controlling interest in APOC. The contract that was set up between the British Government and APOC was to hold for 20 years. The British government also became a de facto hidden power behind the oil company.

APOC took a 50% share in a new Turkish Petroleum Company (TPC) organised in 1912 by Calouste Gulbenkian to explore and develop oil resources in the Ottoman Empire. After a hiatus caused by World War I, it reformed and struck an immense gusher at Kirkuk, Mandatory Iraq in 1927, renaming itself the Iraq Petroleum Company.

In 1920, the APOC also acquired a northern oil concession that had been formally granted in 1916 to a former Russian subject, the Georgian Akaki Khoshtaria. To manage this new acquisition, the APOC formed a new subsidiary, the North Persia Oil Company. Persia, however, refused to accept the new company, giving rise to a lingering dispute over the northern Persian oil.

In 1923, oil was found at the Iraqi/Persian border in Naft Khana/Naft-i-Shah (now Diyala Province), which was considered a "transferred territory" along the Persia-Iraq border. The Khanaqin Oil Company was registered in London as an APOC subsidiary. The quantities henceforth produced in the field were rather insignificant. Naft Khana reverted to the Iraqi government in 1958 after failing to achieve a contractual obligation of 40,000 bbl/day.

During this period, Persian popular opposition to the D'Arcy oil concession and royalty terms whereby Persia only received 16% of net profits was widespread. Since industrial development and planning, as well as other fundamental reforms were predicated on oil revenues, the government's lack of control over the oil industry served to accentuate the Persian government's misgivings regarding the manner in which APOC conducted its affairs in Persia. Such a pervasive atmosphere of dissatisfaction seemed to suggest that a radical revision of the concession terms would be possible. Moreover, owing to the introduction of reforms that improved fiscal order in Persia, APOC's past practice of cutting off advances in oil royalties when its demands were not met had lost much of its sting.

In 1923, Burmah employed Winston Churchill as a paid consultant to lobby the British government to allow APOC to have exclusive rights to Persian oil resources, which were subsequently granted. In 1925, TPC received concession in the Mesopotamian oil resources from the Iraqi government under British mandate. TPC finally struck oil in Iraq on 14 October 1927. In 1928, the APOC's shareholding in TPC, which by now was named Iraq Petroleum Company (IPC), would be reduced to 23.75%; as the result of the changing geopolitics post Ottoman Empire break-up, and the Red Line Agreement. APOC was a 50% co-owner and responsible for the operation of the refinery completed in 1939 at the Haifa terminal of the IPC-owned Kirkuk-Haifa oil pipeline.

1933 agreement

According to Daniel Yergin, "By the end of April 1933, a new agreement was finally forged. The concession area was reduced by three-quarters. Persia was guaranteed a fixed royalty of four shillings per ton, which protected it against fluctuations in oil prices. At the same time, it would receive 20 percent of the company's worldwide profits that were actually distributed to shareholders above a certain minimum sum. In addition, a minimum annual payment of £750,000, irrespective of other developments, was guaranteed. The royalties for 1931 and 1932 were to be recalculated on the new basis, and the 'Persianization' of the workforce was to be accelerated. Meanwhile, the duration of the concession was extended from 1961 to 1993." By 1950, Abadan had become the world's largest refinery.

The Anglo-Persian Oil Company continued its large Persian operations although it changed its name to the Anglo-Iranian Oil Company in 1935. In spite of diversification the AIOC still relied heavily on its Iranian oil fields for three-quarters of its supplies, and controlled all oil in Iran.

Tanker fleet

British Tanker Company Limited (BTC) was formed in 1915, after the Anglo-Persian Oil Company decided to become a fully self-contained operation, directly owning a fleet of tankers for sea transport. On formation, the BTC had an initial budget of $144,000 with which to build seven steam-powered tankers. The Company's first tanker was the British Emperor, which was launched in 1916. The names of the first seven ships, and all later additions to the fleet, bore the prefix British.

Over the next decade, the demand for oil grew throughout the developed world, and the BTC expanded accordingly. By 1924, the fleet numbered 60 ships, with the 60th being the flagship, 10,762 deadweight tonnes (dwt), British Aviator. She was the BTC’s first diesel engine oil tanker, and at that time the most powerful single-screw motor ship in the world.

The economic depression of the early 1930s saw rising unemployment amongst merchant navies around the world. However, the BTC undertook a series of strategic mergers, and coupled with the continued support of the Shah of Iran, the APOC succeeded in strengthening its position within the industry.

In 1939, the British government chartered the whole fleet of 93 tankers to supply fuel to its armed forces during the Second World War. The fleet lost a total of 42 ships sunk during the war.

Within a year of peace in 1945, the BTC fleet had returned to its pre-war total of 93 vessels. The recovery continued with the building of 57 new tankers, each 12,000 dwt, which increased the tonnage of oil transported from Abadan refinery in Iran, whilst remaining light enough for the tankers to pass through the shallow waters of the Suez Canal.

In 1946, Princess Elizabeth launched the tanker British Princess for the APOC, and was given a sapphire brooch to mark the occasion.

In 1951, however, the situation changed dramatically, when the Iranian oil industry was nationalised, and the APOC removed all its staff from Iran.
