The Iran Gas Trunkline (IGAT) is a series of large diameter pipelines constructed from gas refineries in the south of Iran (
Khuzestan and
Bushehr provinces) in order to transfer
natural gas to consumption centers across the country.[1]
As of 2008, there are five trunklines in operation, two under construction and two under planning.[2]
History
IGAT1 was completed in October 1970, supplying gas to the
Southern Caucasus republics of the Soviet Union. In 1975 the
National Iranian Gas Company concluded agreements with
Ruhrgas,
Gaz de France, the Soviet Union, and Austria's
OMV, to supply gas to Western Europe via a proposed IGAT2. Under the arrangement, Iran was to supply additional gas to the Soviet Union, while the Soviet Union was to supply gas to Czechoslovakia from its own gas fields in Siberia. Construction of IGAT2 was halted following the
Iranian Revolution.[3]
IGAT2, 56 inches (1,420 mm) in diameter, was constructed between fajr jam Refinery in
Bushehr Province and
Qazvin in north.
IGAT3, 56 inches (1,420 mm) in diameter, was constructed between
Asalouyeh and Central Province and ultimately to north west of the country.
IGAT4, 56 inches (1,420 mm) in diameter, transfers natural gas produced in South Pars phases 1 to 5 from Asalouyeh to Fars and
Isfahan provinces.
IGAT5, 56 inches (1,420 mm) in diameter, transfers sour gas produced in phases 6, 7 and 8 to Khūzestān Province to be injected into the oil wells.
IGAT6, 56 inches (1,420 mm) in diameter, transfers natural gas produced in
South Pars phases 6 to 10 from Asalouyeh to Khūzestān Province to be consumed there, in the west of the country, and in Iraq.[citation needed] See also:

IGAT7, 56 inches (1,420 mm) in diameter, interconnects east of Asalouyeh to
Hormozgān Province and Sar-Khoon Refinery and transfers natural gas produced in South Pars to Hormozgān,
Sistan, Baluchestan and
Kermān provinces.
IGAT8, 56 inches (1,420 mm) in diameter, originates in east of Asalouyeh and passes by Parsian Refinery in Fars Province onto
Isfahan Province and then to
Qom Province.
IGAT9 (Europe Gas Export Line), 56 inches (1,420 mm) in diameter, originates in east of Asalouyeh and passes by western provinces (Khūzestān,
Īlām,
Kurdistan and
Azerbaijan) and reaches Turkey's border.
