Petroleum industry in Azerbaijan

Onshore oil fields in Azerbaijan

Offshore oil fields in Azerbaijan

The petroleum industry in Azerbaijan produces about 873,260 barrels (138,837 m³) of oil per day and 29 billion cubic meters of gas per year as of 2013. Azerbaijan is one of the birthplaces of the oil industry. Its history is linked to the fortunes of petroleum. It is poised to become an important oil and gas producer once again.

First oil boom

The Nobel Brothers' oil wells in Balakhani, a suburb of Baku.

In 1871, Ivan Mirzoev, an ethnic Armenian who was then an otkupchina monopolist, built the first wooden oil derrick followed by another the next year. Drilling was conducted primitively with a balance arm, whim and manual pump.

Early history

Oil refinery in Baku circa 1912

There is evidence of petroleum being used in trade as early as the 3rd and 4th centuries. Information on the production of oil on the Apsheron peninsula can be found in the manuscripts of most Arabic and Persian authors.

The following paragraph from the accounts of the famous traveler Marco Polo "il Milione" is believed to be a reference to Baku oil: 'Near the Georgian border there is a spring from which gushes a stream of oil, in such abundance that a hundred ships may load there at once. This oil is not good to eat; but it is good for burning and as a salve for men and camels affected with itch or scab. Men come from a long distance to fetch this oil, and in all the neighborhood no other oil is burnt but this."

Historical production

The Turkish scientist and traveller of the second part of the 17th century, Evliya Çelebi, reported that "the Baku fortress was surrounded by 500 wells, from which white and black acid refined oil was produced".

The first detailed description of the Baku oil industry was made by Engelbert Kaempfer, Secretary of the Swedish Embassy to Persia (Iran) in 1683.

In his notes he confirms the existence of places where natural gas discharges to the surface. Kaempfer describes "flaming steppe" as follows: it "...constitutes a peculiar and wonderful sight, for some of the fissures were blazing with big, others with quite flame and was allowing everybody to come up; thirds emitted smoke or at any case minimum perceptible evaporation that was sending off heavy and stinking taste of oil. It was occupying the territory of 88 steps in length and 26 in width."(improved translation needed)

Many 18th and 19th century European accounts of the Caucasus refer to the Fire Temple of Baku at Suraxanı raion, where the fire was fed by natural gas from a cavern beneath the site.

Pre-industrial period

First oil fields in Bibiheybət in the outskirts of Baku

In 1806, the Russian empire occupied Baku Khanate and took monopolistic control of oil production. Later exclusive rights to produce oil were given to individuals, thereby creating the otkupchina lease system.

Oil extraction methods in those times were very primitive —mainly hand dug wells, drilled to very shallow depths. The production volume of those years can be judged from data provided in 1842 by the Caspian Chamber of the Department of State Property Ministry. It refers to 136 wells around Absheron, which produced 3,760 cubic metres (23,600 bbl) per year, and this oil was exported to Persia, where it was used in lighting as well as a source for ointments and other traditional remedies.

As a result of otkupschina monopoly and the absence of growing demand, annual oil production in the first half of 19th century remained unchanged at 250–300 poods (4–5 thousand tons). In 1813, the number of producing wells was 116, then 125 in 1825, 120 in 1850, and only 218 in 1860. Otkupschina system meant that oil production was monopolized by set of individuals who saw no incentive to increase production or improve drilling methods.

In 1846, under the supervision of state advisor V.N. Semyonov engineer Alekseev drilled a 21 m deep well using a primitive percussion drilling mechanism, in Bibiheybət to explore for oil, with positive results. More than a decade later, on August 27, 1859, "Colonel" Edwin L. Drake struck oil on American soil for the first time.

A small petrochemical industry sprung up around Baku, as demand for kerosene soared locally. Vasily Kokorev, Peter Gubonin and German baron N.E. Tornow built the first kerosene factory in Surakhany. The factory was used to produce kerosene out of "kir", an asphalt-like substance. In 1859, N.I. Vitte, a Tiflis pharmacist, built the second paraffin-producing factory on Pirallahi Island.

As a result, there was flurry of financial activity and various bank societies and organization were created. In 1884, the oil barons in Baku established their own organization, the Oil Extractors Congress Council for the discussion of oil business. They created their own magazine, Neftyanoe Delo (Oil Business), a library, school, hospital, and pharmacy. For six years, the Council of Oil Extractors Congress was directed by Ludvig Nobel.

The oil industry greatly influenced the architectural appearance of Baku as a modern city. Administrative, social and municipal institutions were established which, in turn, made decisions about the city's illumination, roads, streets, buildings, telephone stations, and horse-drawn trolleys. Gardens and parks were laid out and hotels, casinos and beautiful stores were built.

First, exclusive rights to develop Baku oil fields were in the hands of Russian-registered businesses, and only in 1898 foreign companies were granted rights to explore and develop oil fields as well as to participate in annual bidding process. Between 1898 and 1903 British oil firms invested 60 mln rubles in Baku oil fields. Ethnic Armenians also contributed to the oil production and drilling around Baku. Armenians reportedly ran almost one-third of the region's oil industry by 1900. Such Armenians included G.M. Lianozov Sons, Adamov, Alexander Mantashev, Hovhannes Mirzoyan, and more.

Oil production

The main oil-producing regions were located near Baku at Sabunchy, Surakhany and Bibi-Heybat. Until the beginning of the 20th century, the Sabunchi region was producing 35 percent of Baku's oil, and the Bibi-Heybat region produced 28 percent, followed by the Romany and the Balakhany regions. Blowout oil gushers made up the main portion of all oil production in the early days although this was a very uneconomical and environmentally harmful process. However, blowout production decreased as the equipment was improved. In 1887 blowouts accounted for 42 percent of the recovered oil, but in 1890 it had decreased to 10.5 percent.

In oil industry of pre-revolutionary Russia foreign capital dominated the sector. On the eve of the World War I three companies ("Russian General Oil Company", "Royal Dutch Shell" and "Partnership of Nobel Brothers.") held 86% of all share capitals and controlled 60% of oil production. In 1903, 12 English companies with capital equaling to 60 mln. rubles were functioning in Baku region. In 1912, Anglo-Dutch firm "Shell" obtained 80% shares of Caspian-Black Sea Society "Mazut", which had belonged to Rothschild Banking-house. Other British firms purchased oil operations from Hajji Zeynalabdin Taghiyev.

In 1898, the Russian oil industry exceeded the U.S. oil production level. At that time, approximately 8 million tons were being produced (160,000 barrels (25,000 m³) of oil per day). By 1901, Baku produced more than half of the world's oil (11 million tons or 212,000 barrels (33,700 m³) of oil per day), and 55 percent of all Russian oil. Approximately 1.2 million tons of Baku kerosene were also sold abroad.

Local oil barons and foreign oil companies

• Branobel Operating Company — largest single oil producer in Azerbaijan at 25,000 bop/d in 1914. Largest refiner and transporter of oil, as well as retailer of kerosene in Europe. Markets of France, Turkey, Greece and Germany were fully supplied by Nobel-produced kerosene and other products.
• De Rothschild Frères — trading and shipping in association with Shell. Possessed largest tanker fleet in the Caspian after Nobels.
• Alexander Mantashev — an Armenian oil tycoon, the owner of the third largest oil company in Baku, A.I. Mantashev & Co., by 1904.
• Royal Dutch Shell — Shell acted through following associated companies: the Caspian Black Sea Society, Caucasus, S.M. Shibayev, and Co. Shell-led consortium produced a fifth of Russian output up to 1914. Royal Dutch Shell's output from the Baku oil fields was 15,000 boppd in 1914.
• Zeynalabdin Taghiyev — oil, textiles and fishing. His firm was producing 1,900 bbl/d (300 m³/d) in 1887 and occupied 4th place in refining business "
• Aga Musa Nagiyev — oil and real estate. He was the second-largest oil producer and largest native producer
• Murtuza Mukhtarov — oil drilling services.
• Shamsi Asadullayev — oil shipping, largest native industrialist.
• James Vishau and Anglo-Russian Oil Company
• Trade House Benkendorf and Co — oil production.
• The Russian Oil General Corporation  — established in London in 1912 by the most important Russian and foreign banks, united 20 companies. These included A.I. Mantashev & Co., G.M. Lianozov Sons, Adamov and sonsMoscow-Caucasus Trade Company, Caspian Partnership, Russian Petroleum Society, Absheron Petroleum Society and others. This agglomeration produced more than 30% of Russian oil by 1916.

Distribution of Russian Oil Producers in 1900–13

There were other entrepreneurs with lower rank who also made contributions to industrial development of Azerbaijan, such as Haji Baba Alekperov, Agasibek Ashurbeyov, Ali Bala Zarbaliyev, Kerbalay Zarbaliyev, Huseyin Melikov, G. Bagirov, G. Aliyev, S. Zminov, Amir-Aslanov brothers and others were owners of oil-field areas in Sabunchi, Balakhani, Romani, Shubani, Bibi-Heybat.

Subsurface and drilling

By the late 1890s, large companies started to employ geologists to describe and map prospective structures. Geologist and oil specialist Dmitry Golubyatnikov began a systematic investigation of Absheron and predicted the availability of oil deposits in Surakhany field. In 1901, the Pirallahi oil field was discovered and put on production. Scientists like Ivan Gubkin, Golubyatnikov and Uskin described the productive series deposits of Azerbaijan and the process generation for the first time in 1916.

By the early 20th century, innovation started to improve hitherto backward well drilling practices. Most of the wells up to that time were drilled by cable-tool drilling method, which limited the exploitation to shallow depth.

Qualified engineers (of which Fatulla Rustambeyov is the first Azeri national) contributed to the improvement of well designs. By early 1913 the following changes occurred in some of largest producers such as Branobel.

• Transition from percussion cable-tool drilling to rotary drilling using electrical drive.
• Use of thread line casing pipe instead of valve strings during drilling.
• Replacement of wooden derricks with metal ones.
• The process of gaslift was tested for the first time in 1915 in Romani field.
• The compression during transportation of oil and gas was introduced in 1911.

Storage and transportation

In 1858, one of the major shipping companies on the Caspian Sea — joint-stock company "Kavkaz and Merkuriy" was established and served as the first oil shipping outlet.

Great changes were introduced in the area of oil storage by Nobels. To counteract the waste of the ground pits, vessels and lakes where great quantities of oil evaporated or simply penetrated back into the ground, the company started to use iron reservoirs for oil storage.

The first successful oil tanker in the world — a refurbished metal ship called "Zoroastr" — was built in 1877 in Sweden by Nobels. By 1890 345 tankers, including 133 steam vessels and 212 sailing vessels were sailing on the Caspian Sea. For instance, Mazut Trading Co, created by the Rothschild Frères in 1898, possessed 13 tankers in Caspian Sea alone. During these years, native Azerbaijani ship-owners appeared, of which the largest fleet belonged to Shamsi Asadullayev.

In 1877, construction of the first ever oil pipeline linking Surakhany oil field and refinery in Baku was completed. By 1890, there were more than 25 pipelines totaling 286 km.

The Nobel Brothers were the first to introduce railway tanks (cisterns) for oil transportation, when the railway link between Baku and Tiflis was built in 1883. The situation with limited exporting options was solved by the construction of the Baku–Batum pipeline. After 1936 Batum renamed to Batumi. Construction began in 1897 and was completed 10 years later under supervision of Professor N. L. Szhukin.

Revolution and Soviet Republic

Several oil crises jolted Russia around 1903, when constant strikes, violence and ethnic strife during Russian Revolution of 1905 led to fall in the oil production from the peak of 212,000 bbl/d (33,700 m³/d). The relative calm of the early 1910s was disrupted by World War I, when production of oil steadily decreased to reach the lowest level of just 65,000 bbl/d (10,300 m³/d) by 1918 and then dropped even more catastrophically by 1920. As a result of civil unrest no oil export was possible, oil storage facilities were damaged and wells were idle. The government of Democratic Republic of Azerbaijan was unable to restore the damage done to the oil industry during its time in office between 1918 and 1920.

Since 1918, more 5 mln ton of oil accumulated in Azerbaijan. After the occupation of Azerbaijan by Bolsheviks, all oil supplies were directed to Russia. All oil assets in the country were nationalized and Azneft State company was formed. In 1920, Alexander P. Serebrovsky, soon to be known as the "Soviet Rockefeller", was named head of Azneft.

In 1920, only 1800 qualified specialists worked in the Russian oil industry of which 1232 worked in Azerbaijan. The industry urgently needed technology, education and specialists. The scientific exchange started with the US, where visitors from Baku were seconded to oil-fields in Pennsylvania, Oklahoma, California, Texas, learned new methods of well deepening and exploitation. The Azerbaijan State Oil Academy was established in 1920 to train oil specialists.

By the late 1920s, production stabilized. In 1928–29, oil production in the USSR equaled to 13.5 mln t including Azerbaijan's 8.7 mln t. By 1940, the total production of Azerbaijan — 23.5 mln. t (475,000 bbl/d (75,500 m³/d)) — was a historical record not broken until 2005.

Advancement in drilling and logging practices

For the first time in Russia in 1925, Baku engineer M.M. Skvortsov constructed a device for the automatic movement of a chisel, which became known as the "automatic driller". By 1930, electrical logging tools were used in the wellbore by Schlumberger in the Surakhany oil field.

A new technology in drilling was introduced in Baku: electrical aggregates with exact control of the number of rotations came into widespread use. By the early 1930s, about third of well stock was operated with pumps using gas lift. In 1933, the first deviated well was drilled in the Bibi-Heybat field.

Other firsts were:

• 1936 saw the beginning of the industrial application of the multi-stepped turbo drill without a reducer which had been invented by Shumilov, Taghiyev and others.
• For the first time in the world, an oil well was drilled by the electro-drilling construction which was introduced by engineers Ostrovsky, Aleksandrov and others in Kala oil field

World War II

Between 1939 and 1940, when the Soviet Union was supplying oil to Nazi Germany, Britain and France planned a major strategic bombing offensive called Operation Pike to destroy the oil production facilities in Baku.

During that first year of the war, Azerbaijan produced 25.4 million tons of oil — a record. By the Decree of the Supreme Soviet of the USSR in February 1942, the commitment of more than 500 workers and employees of the oil industry of Azerbaijan was recognised by the giving of orders and medals of the USSR.

By the end of the year, so many engineers and oil workers had left for the war front that positions had to be filled by women. By the summer of 1942, more than 25,000 women or 33% of all the workers were working 18-hour shifts in the oil industries. At refineries and chemical plants, the percentage of women was even higher, estimated at 38%. By 1944, women's participation had grown to 60%. Veterans and retirees also returned to the oil fields to help. It was not uncommon for the workforce of small towns (i.e. Kıncıvo) to completely and rapidly convert toward dependence on the oil industry during this period.

Hitler was determined to capture the oil fields of the Caucasus, in particular Baku, as it would provide much needed oil-supplies for the German military which was suffering from blockades. The 1942 German offensive codenamed Case Blue saw a determined attempt to seize the oil fields in a large scale advance into the area. The plan was to attack Baku on September 25, 1942. Anticipating the upcoming victory, Hitler's generals presented him a cake of the region, where piece showing Baku was given to Hitler. But the Axis forces were surrounded and eventually defeated at Stalingrad forcing a retreat from the region. During World War II (1939-1945) - control of oil supply from Baku and Middle East played a huge role in the events of the war and the ultimate victory of the allies. Cutting off the oil supply considerably weakened Japan in the latter part of the war.

Post-war period

Beginning of offshore exploration

The oil production from the existing fields started to decline after World War II, as a result of catastrophic over-production and under investment. However real potential for new discoveries was felt to be present offshore.

As far back as 1864, a German mineralogist and geologist H.V.Abikh surveyed and reported structures present on the seabed of the Caspian.

In the early 1930s, engineers proposed construction of offshore wells timber piles, connected by a causeway, and the first such well was laid in the open sea on the depth of 6 m to the east from filled Bibi-Heybet bay.

In 1945, oil engineers S.A. Orujev, Y. Safarov proposed a method of tubular collapsible constructions for offshore bases. This construction enabled quick installation under oil-rig at any season. In 1947, a group of oilmen developed the trestle method of linking development rigs and processing facilities. Average height of trestle above sea level is 5–7 m, and width of causeway was about 3.5 m. In 1948, construction of trestles and other causeways started on Pirallahi and Oil Rocks.

Wooden trestle employed at Oily Rocks

Oily Rocks Saga

One of the striking examples for offshore oil deposit development is "Oily Rocks" — "Neft Dashlari". It is located to the south-east of Absheron Archipelago. In "Oily Rocks" sea depth ranges from 10 to 25 m, though part of the oil pool reaches 60 metres depth. Oil prospecting with geological survey, structure drilling, seismic prospecting and preliminary drilling started in 1945.

On August 24, 1949, the first offshore exploration well at Neft Dashlari (Oil Rocks) was spudded after the causeway was built. On November, at a depth of 1,000 metres, the well N1 tested oil with a rate of 700 bbl/d (110 m³/d). Neft Dashlari is referred to as "The Island of Seven Ships" because during construction of the bridge-head, disused ships were sunk to provide a solid base for causeways.

Intensive development began in 1950. Development from multiple drilling sites connected by trestle bridges also employed deviated holes. In 1953, to maintain the reservoir pressure, a water flood was applied. The field is still delivering about 15,000 bbl/d (2,400 m³/d) after 50 years of exploitation.

Offshore exploration in the 1960s and 1970s

As a result of intensive geological and geophysical mapping during 1950–1960, main Caspian oil-and-gas bearing structures were determined. The discoveries included such fields as Darwin Bank, Gum Deniz "Canub", "Gurgani-sea", "Chilov Island", "Hazi Aslanov", "Sangachalli-sea", "Duvanni-sea", "Bulla Island" and Peschany.

One of the largest offshore fields "Sangachal-deniz" was drilled several times since 1959, but success came only in 1965. "Duvanni-deniz field" discovery well was tested in May 1963 with an output of 700 bbl/d (110 m³/d). This field has about 700 million barrels (110,000,000 m³) of oil reserves.

Several large oil and gas fields were discovered and put into production between 1968 and 1975: Bahar (1968), Sangachali-Duvanni (1969), Bulla Deniz (1975).

Production reached its peak in 1967 with 414,000 bbl/d (65,800 m³/d) being produced and henceforth started to decline as Oily Rocks development was complete. Gas production increased steadily through until the 1990s until the decline of Bahar and Bulla gas fields ensued.

As a result of modern methods of exploration being employed, four new multireservoir fields were opened in the Caspian at a depth of 200 meters: Gunashli (1979), Chirag (1985), Azeri (1988) and Kapaz (1989). The Caspian was covered by extensive 2D seismic grid and 3D seismic was attempted, however unsuccessfully. The discovery of Azeri-Chirag-Guneshli field complex was the last but significant achievement by Azeri Soviet explorationists. The shallow portion of Guneshli, where water depth allowed oil development was put in production by 1989 and now delivers 120,000 bbl/d (19,000 m³/d).

In Chirag, drilling took place via semi-submersible drilling equipment at a depth of 200 meters — an offshore record for USSR. The Azeri-Chirag-Guneshli complex contains more than 16 billion barrels (2.5×10⁹ m³) of oil in place.

"Contract of the Century" and following years

After gaining independence Azerbaijan started to attract badly needed foreign investment into the country.

The implementation of the 20 PSA contracts (requiring $60 billion investment) that have been concluded so far is an integral part of Azerbaijan's oil strategy. Azeri, Chirag and deep-water Gunashli (ACG)-International Contract No. 1 was signed by President Heydar Aliyev and the participating international companies on September 20, 1994, ratified in Parliament on December 2, and went into effect on December 12. Because of its potential reserves estimated at 6 billion barrels (950,000,000 m³) of oil, this project is often referred to as the "Contract of the Century". The projected investment for this project is $13 billion.

Oil as natural wealth of Azerbaijan depicted on an AZM 1000 banknote (2001)

A few months later in 1995, a consortium was organized known as the Azerbaijan International Operating Company (AIOC). Originally AIOC was composed of eleven major international companies: BP (UK), Amoco (U.S.), LUKoil (Russia), Pennzoil, (now Devon of U.S.), UNOCAL (U.S.), Statoil (Norway), McDermott (U.S.), Ramco (Scotland), TPAO (Turkey), Delta Nimir (now Amerada Hess of U.S.), and SOCAR (Azerbaijan).

Since then Exxon, now ExxonMobil (U.S.); ITOCHU (Japan); and INPEX (Japan) have joined the consortium. McDermott, Ramco and LUKoil have since sold their shares. AIOC's first president was Terry Adams (UK) of British Petroleum (BP), the company which operates the offshore oil platforms and the onshore Sangachal Terminal.

However, the problem of how to deliver the oil to European markets existed. This problem was solved by the agreement for the construction of the Baku-Tbilisi-Ceyhan pipeline among Azerbaijan, Georgia and Turkey in 1998.

The Baku-Tbilisi-Ceyhan pipeline was officially opened on July 13, 2006 and now transports crude oil 1,760 km (1,090 mi) from the Azeri-Chirag-Guneshli oil field in the Caspian Sea to the Mediterranean Sea. The oil is pumped from the Sangachal Terminal close to Baku, via Tbilisi the capital of Georgia, to Ceyhan a port on the south-eastern Mediterranean coast of Turkey. It is the second longest oil pipeline in the world (the longest being the Druzhba pipeline from Russia to central Europe).

The BTC pipeline is expected to make a major contribution to the development of world energy supply with its more than 1 million barrels (160,000 m³) per day capacity. Thanks to this project Turkey is also expected to earn about $300 million annually. Around 15,000 people were employed during the construction of the pipeline which cost $3 billion

Shah Deniz field, discovered in 1999, is one of BP's largest gas field finds in recent decades. The Shah Deniz gas plant at Sangachal Terminal started up in 2007 and transformed Azerbaijan into a major gas producer. Stage 1 of Shah Deniz project is now complete and supplies Georgia and Turkey with 8 bcma of natural gas via the South Caucasus Pipeline. In December 2013, Stage 2 of the Shah Deniz Project has been approved and is being designed. The Shah Deniz Stage 2 hydrocarbons are planned to be transferred to Turkey and Europe through the TANAP and TAP export pipelines.

On September 9, 2011, French energy giant Total S.A. which has been operating in Azerbaijan since 1996, announced a major gas discovery in Absheron gas field offshore 100 km southeast of capital Baku. The field is estimated to have around 300 billion cm of gas subsequently boosting Azerbaijan's gas reserves from 2.2 to 2.5 trillion m3.
