The South Caucasus Pipeline (also known as Baku–Tbilisi–Erzurum Pipeline, BTE pipeline, or Shah Deniz Pipeline) is a natural gas pipeline from the Shah Deniz gas field in the Azerbaijan sector of the Caspian Sea to Turkey. It runs parallel to the Baku–Tbilisi–Ceyhan pipeline (oil).



On 21 May 2006, the commissioning gas was pumped to the pipeline from the Sangachal Terminal. [1] First deliveries through the pipeline commenced on 30 September 2006. Deliveries of gas from Shah Deniz gas field started on 15 December 2006. [2]

On 12 August 2008, the pipeline operator BP closed the pipeline for safety reasons because of the South Ossetia conflict. [3] Gas supplies were resumed on 14 August 2008. [4]


The 42-inch (1,070 mm) diameter gas pipeline runs through the same corridor as the Baku–Tbilisi–Ceyhan pipeline until Erzurum, where BTC turns south to the Mediterranean. It is 692 kilometres (430 mi) long, of which 442 kilometres (275 mi) is in Azerbaijan and 248 kilometres (154 mi) in Georgia. [1] The initial capacity of the pipeline was 8.8 billion cubic metres (310 billion cubic feet) of gas per year. [5] For the second stage of the Shah Deniz development, the capacity would be increased up to 25 billion cubic metres (880 billion cubic feet) by adding additional looping and two new compressor stations, costing $3 billion. [6] As the pipeline has the potential to be connected to Turkmen and Kazakh producers through the planned Trans-Caspian Gas Pipeline, Azerbaijan has proposed expanding its capacity up to 60 billion cubic metres (2.1 trillion cubic feet) by building a second line of the pipeline. [7]

Economic impact

The first aim of the pipeline is to supply Turkey and Georgia. As a transit country, Georgia has rights to take 5% of the annual gas flow through the pipeline in lieu of a tariff and can purchase a further 0.5 billion cubic metres (18 billion cubic feet) of gas a year at a discounted price. In the longer term, it will supply Europe with Caspian natural gas through the planned Southern Gas Corridor pipelines, such as the Trans Adriatic Pipeline and Trans-Anatolian gas pipeline. [6]

Project company

The pipeline is owned by the South Caucasus Pipeline Company, a consortium led by BP and SOCAR. The shareholders of the consortium are:

The technical operator of the pipeline is BP and the commercial operator is Statoil. According to the PSA agreement, the commercial operatorship of the SCP was transferred to SOCAR starting on 1 January 2015.

South Caucasus Pipeline expansion (SCPx)

As a part of the Shah Deniz Full Field Development (FFD), otherwise called the Shahdeniz-2 project, BP will expand the pipeline through capacity extension by putting two additional compressor stations in Georgia and Turkey. This will almost triple the current transportation capacity of the pipeline up to 20 bcm/year. [8]

This capacity increase would be able to accommodate an additional 16 bcm gas coming from the SD-2 project.

Baku–Tbilisi–Ceyhan pipeline Oil pipeline

The Baku–Tbilisi–Ceyhan (BTC) pipeline is a 1,768 kilometres (1,099 mi) long crude oil pipeline from the Azeri–Chirag–Gunashli oil field in the Caspian Sea to the Mediterranean Sea. It connects Baku, the capital of Azerbaijan and Ceyhan, a port on the south-eastern Mediterranean coast of Turkey, via Tbilisi, the capital of Georgia. It is the second-longest oil pipeline in the former Soviet Union, after the Druzhba pipeline. The first oil that was pumped from the Baku end of the pipeline reached Ceyhan on 28 May 2006.


The State Oil Company of Azerbaijan Republic, largely known as SOCAR is fully state-owned national oil and gas company headquartered in Baku, Azerbaijan. The company produces oil and natural gas from onshore and offshore fields in the Azerbaijani segment of the Caspian Sea. It operates the country's only oil refinery, one gas processing plant and runs several oil and gas export pipelines throughout the country. It owns fuel filling station networks under the SOCAR brand in Azerbaijan, Turkey, Georgia, Ukraine, Romania and Switzerland.

Nabucco pipeline A proposed natural gas pipeline from the Turkish-Bulgarian border to Austria

The Nabucco pipeline was a project of the natural gas pipeline from Erzurum in Turkey to Baumgarten an der March in Austria to diversify natural gas suppliers and delivery routes for Europe. The pipeline was to lessen European dependence on Russian energy. The project was backed by several European Union states and the United States and was seen as rival to the Gazprom-Eni South Stream pipeline project. The main supplier was to be Iraq with potential supplies from Azerbaijan, Turkmenistan, and Egypt.

Shah Deniz gas field

Shah Deniz gas field is the largest natural gas field in Azerbaijan. It is situated in the South Caspian Sea, off the coast of Azerbaijan, approximately 70 kilometres (43 mi) southeast of Baku, at a depth of 600 metres (2,000 ft). The field covers approximately 860 square kilometres (330 sq mi). Stretching out over 140 square kilometres, the reservoir is similar in size and shape to Manhattan Island.

Petroleum industry 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.


Azeri–Chirag–Gunashli or Azeri–Chirag–Deepwater Gunashli is a complex of oil fields in the Caspian Sea, about 120 kilometres (75 mi) off the coast of Azerbaijan. It consist of Azeri and Chirag oil fields, and the deepwater portion of the Gunashli oil field. An overall estimated area of the development is 432.4 square kilometres (167.0 sq mi). It is developed by the Azerbaijan International Operating Company, a consortium of international oil companies, and operated by BP on behalf of the consortium. The ACG fields have estimated recoverable reserves of about 5 to 6 billion barrels of petroleum. As of the end of 2005, the production rate from eight pre-drilled wells at the platform was approximately 240,000 barrels per day (38,000 m3/d).

Trans-Caspian Gas Pipeline

The Trans-Caspian Gas Pipeline is a proposed subsea pipeline between Türkmenbaşy in Turkmenistan, and Baku in Azerbaijan. According to some proposals it will also include a connection between the Tengiz Field in Kazakhstan, and Türkmenbaşy. The Trans-Caspian Gas Pipeline project is purposed to transport natural gas from Turkmenistan and Kazakhstan to European Union member countries, circumventing both Russia and Iran. It is also considered as a natural eastward extension of Southern Gas Corridor. This project attracts significant interest since it will connect vast Turkmen gas resources to major consumer geographies as Turkey and Europe.

Southern Gas Corridor

The Southern Gas Corridor is an initiative of the European Commission for a natural gas supply route from Caspian and Middle Eastern regions to Europe. The goal of the Southern Gas Corridor is to reduce Europe's dependency on Russian gas and add diverse sources of energy supply. The route from Azerbaijan to Europe consist of the South Caucasus Pipeline, the Trans-Anatolian Pipeline, and the Trans-Adriatic Pipeline. The total investment of this route is estimated US$45 billion. The main supply source would be the Shah Deniz gas field, located in the Caspian Sea.
