Iran Gas Trunkline

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]

Iran's Oil and Gas Fields and Infrastructures

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]
