    IRAN'S AGGRESSIVE NATURAL GAS EXPANSION PLANS
    By Hedayat Omidvar

    Posted on Sep. 17, 2007

    As global energy demand rises, natural gas increasingly plays a
    strategic role. The sector is poised for tremendous growth over the
    next two decades and some believe that it may overtake oil as the
    prime fuel between 2020 and 2030. Iran's huge proven reserves -
    some 28 trillion cubic meters (about 995 trillion cubic feet) ­-
    should make it a key player in the emerging global gas business.

    These impressive reserves figures - second only to the Russian
    Federation's - underscore Iran's enormous potential. The National
    Iranian Gas Company (NIGC) plans the steady expansion of transmission
    and processing infrastructure in a program aimed at increasing imports
    and exports of natural gas, which will take natural gas to parts
    of the Islamic Republic not yet reached by distribution systems and
    boost exports by pipeline and in the form of LNG.

    More than 60 percent of Iran's gas reserves are located in
    non-associated undeveloped or partially developed fields. The major
    non-associated gas fields include South Pars (280-500 tcf of gas
    reserves), North Pars (50 tcf), Kangan (29 tcf), Nar (13 tcf), and
    Khangiran (11 tcf). There are also several other large gas fields
    with multi-tcf reserves. However, most of the gas will come from the
    offshore South Pars gas field, which is being developed in stages.

    Supplementing that supply will be imports from Turkmenistan and,
    soon, from Azerbaijan.

    South Pars was first identified in 1988 and was originally thought to
    contain just 128 tcf. Current estimates show it to contain at least
    280 tcf (with some estimates going as high as 500 tcf) as well as
    over 17 billion barrels of condensate.

    By 2010, more than 500,000 barrels per day of condensates could be
    produced at South Pars, mainly for domestic consumption. Designed
    in 28 phases, so far only 18 phases have been activated. By 2015,
    condensate production from South Pars phases 1-14 is expected to reach
    628,000 bpd. Besides condensate production and enhanced oil recovery,
    South Pars natural gas is intended for both domestic consumption and
    exports. South Pars can produce more than 400 million cubic meters
    per day (14.2 billion cubic feet/day). Considering internal demand,
    half of this production can be assigned to exports.

    Internal consumption represents a rapidly growing demand on Iranian
    gas supply. The NIGC expects internal consumption to rise to 156.2
    bcm per year in 2009 (13.2 bcf/day). (Editor's Note: The National
    Iranian Oil Company is purported to raise oil production to about
    5.4 million barrels per day by 2009.)

    Market Expansion

    By 2009, NIGC expects to have 29,400 kilometers of gas transmission
    pipeline in place and a distribution network of 125,000 km. Domestic
    gas consumption that year will represent 69 percent of the Iranian
    energy market, and 54 million Iranians will have access to natural
    gas - about 80 percent of the population.

    NIGC plans to invest about $18 billion through 2009 in high-pressure
    gas pipelines, compressor stations, gas-processing plants, underground
    storage, distribution networks, and maintenance.

    Pipeline Projects

    Many of the pipeline projects planned by NIGC will be attached to the
    Iranian Gas Transmission (IGAT) system. Transmission pipelines with
    a length of 20,000 km take gas from various sources to destinations
    across the whole country. Lines with diameters of 56, 48, and 42 inches
    have been employed to carry more than 500 million cubic meters per day
    (17.7 bcf/day) of natural gas.

    The IGAT IV pipeline will carry 110 (mcm/day) of gas from South
    Pars and the Parsian gas plants to consumption areas. The project
    includes 1,030 km of 56-inch pipe in two sections and two compressor
    stations. Parts of IGAT IV have begun service. The main part of the
    pipeline was connected with the Pol Kaleh compressor station in Isfahan
    in 2004; a 351-km section to Fars Province became operational in 2004.

    A second stage of IGAT IV will include a 42-inch spur line to Kerman,
    a 24-inch line to serve a Fars petrochemical plant, a second 40-inch
    line to Yazd, and a 40-inch Isfahan-Mobarakeh pipeline.

    The 56-inch IGAT V trunkline will carry 75 mcm/day of sour gas from
    South Pars Phases 6-8 to Khoozestan oil fields for injection. It will
    connect Assaluye and Agha Jari, a distance of 504 km, and will have
    five compressor stations.

    The IGAT VI pipeline will generally parallel IGAT V to serve gas
    needs of Bushehr and Khoozestan provinces, including oil field
    injection. With a length of 492 km and a diameter of 56 inches, it will
    have a capacity of 90 mcm/day. Two compressor stations are planned.

    IGAT VII, 860 km of 42 to 56-inch line, will carry gas produced in
    South Pars Phases 9 and 10 for use in Sistan and Baluchestan provinces
    in southern Iran, and possibly for export to the U.A.E., Pakistan,
    and India.

    IGAT VIII, a 1,050-km, 56-inch line, will carry South Pars gas to
    the Parsian gas plant and north to a line serving Tehran. It will
    have 10 compressor stations with a total of 1.8 million hp.

    To meet growth in gas demand in the northern and eastern provinces
    of Semnan, Khorasan, Golestan, and Mazandaran, NIGC plans a second
    pipeline between Parchin and Sangbast, 790 km long with a diameter of
    48 inches, and a 110-km, 40-inch segment between Miami and Jajarm. The
    system will have four compressor stations and will handle South Pars
    gas delivered through IGAT VIII.

    To serve the western and northern provinces of Hamadan, Kordestan,
    Zanjan, as well as East and West Azerbaijan, NIGC plans to lay 280
    km of 48-inch pipeline between a compressor station at Saveh and
    the city of Bijar, and 192 km of 40-inch pipeline between Bijar and
    Miandoab. Other segments with diameters of at least 30 inches will
    boost pipeline lengths planned for this region to 950 km.

    Gas Processing Projects

    Seven gas processing plants have recently been completed or are planned
    and under construction in Iran. The Parsian plant began treatment
    operations in 2003, dehydrating 20 mcm/day of gas from Tabnak field
    and stabilizing 12,000 bpd of condensates.

    Construction of the new processing facilities will proceed in two
    phases, one with an inlet capacity of 48 mcm/day and the other, 28
    mcm/day. The complex is designed for annual yields of 85,000 tons of
    ethane, 11 million barrels of pentanes-plus, 310,000 tons of butane,
    and 450,000 tons of propane.

    The Bidboland II plant will sweeten and process 57 mcm/day of gas at
    facilities that will be built about 14 km southeast of the existing
    Bidboland plant. Fed by gas from the Pazanan, Gachsaran, and Bibi
    Hakimeh fields, the new plant has design output capacities of 15
    bcm of sweet gas, 1.48 million tons of ethane, 1.51 million tons of
    propane and butane, and 860,000 tons of natural gasoline.

    About 6 bcm per year from the plant are targeted for oil-field
    injection, the rest for delivery into the gas grid. Ethane will go to
    a petrochemical plant at Arvand. The other products will be exported
    through Bandar Mahshahr.

    In a separate project, NIGC plans a gas processing plant 25 km
    northwest of the city of Ilam and 12 km west of Chavar in western
    Iran. The Ilam plant will process gas from Tange Bijar and Kamankooh
    fields.

    Built in two phases, it will have an inlet capacity of 10 mcm/day and
    will supply dry gas to cities in Ilam Province and the transmission
    network and liquids to a petrochemical plant at Ilam.

    NIGC also plans a small processing plant at Masjed Soleiman with
    inlet capacity of 1 mcm/day and is studying a plant able to process
    14 mcm/day at South Gesho sour gas field in Hormuzgan Province. The
    South Gesho facility, near an existing plant at Sarkhon, would have
    two trains with identical inlet capacities.

    After removal of 600 tons/day of sulfur and 9,000 bpd of condensate,
    sweet gas would move to markets in the southeastern part of the
    country, including some to a power plant at Bandar Abbas.

    Storage Projects

    To overcome seasonal fluctuations in consumption, installation of
    underground gas storage has been recognized as the best choice. Three
    underground storages are under study, with some degree of progress,
    to ensure natural gas supply to internal users and export destinations.

    NIGC has also identified several reservoirs that might be converted
    for underground gas storage. One of them is Sarajeh gas and condensate
    field, about 40 km east of Qom, whose production rates have been
    restricted by surface equipment for about 45 years. NIGC believes
    that by working over old wells and drilling new ones it can deplete
    the reservoir in two years and convert it to storage. Another prospect
    for gas storage is the Yortsha Dome saltwater reservoir 25 km south of
    Varamin. NIGC has acquired 2D and 3D seismic data over the reservoir
    and plans to drill vertical and horizontal wells to prepare it for
    storage. Another saltwater reservoir under study for use as gas
    storage is the Talkheh Dome in central Iran, which also contains
    negligible amounts of light and heavy hydrocarbons. A single well
    drilled in 1960 found the structure. NIGC has 2D seismic data from
    the area and plans a 3D survey.

    Other areas that NIGC thinks might have reservoirs amenable to gas
    storage are in the provinces of Abardejno, Siahkooh, Marehtapeh,
    Prandak, and East Azerbaijan.

    Expansion of Iran's gas industry follows a strategy in place since
    the early 1990s to displace oil with gas in domestic consumption. In
    2002, gas moved ahead of oil in Iran's total energy consumption. Gas
    now claims 70 percent and oil, 30 percent of Iran's overall primary
    energy use.

    Export Markets

    The strategic role of the Persian Gulf and the huge amount of gas
    reserves in this area have provided a good opportunity for Iran to
    export gas to consuming countries through pipeline or in the form of
    LNG. NIGC believes pipeline exports can reach 44 bcm/year in 2009 and
    110 bcm/year by 2020. Besides Turkey, potential customers for Iranian
    gas include Ukraine, Europe, India, Pakistan, Armenia, Azerbaijan,
    Georgia, and China. NIGC is targeting LNG exports from three planned
    liquefaction projects to China, Thailand, and India of 35 mcm/day in
    2009 and 180 mcm/day in 2020.

    Assalouyeh and Kish Island have been named as possible LNG export
    terminals.

    Oman and Iran have signed an agreement to develop offshore gas fields
    in Iran and take the gas to Oman.

    The gas from the joint Bukha-Hengam and other fields would be converted
    into LNG at Oman's Qalhat LNG plant and marketed as exports by a joint
    company. The agreement also calls for joint petrochemical projects.

    Bahrain has started discussions with Iran over importing natural gas
    through a new pipeline by 2015.

    As part of its plans to meet the Kingdom's future electric power
    needs, Bahrain has implemented a twin-pronged strategy to boost gas
    supply. This involves both increasing domestic output and negotiating
    import agreements with its gas-rich neighbors.

    The project for transferring gas to Europe is also economically
    attractive and will benefit all parties involved. Turkey and Ukraine
    have been considered as alternative routes, but the former is less
    expensive.

    By the end of 2007, Iran expects to be exporting about 300 bcf/year
    of gas to Europe via Turkey.

    Since the discovery of natural gas reserves in Iran's South Pars
    fields, the Iranian government has increased efforts to promote
    higher gas exports abroad. The prospects for profit are especially
    good in south Asian countries like India and Pakistan, where natural
    gas reserves are low and energy demand exceeds supply. Pakistan and
    Iran signed a preliminary agreement for the construction of a natural
    gas pipeline linking the Iranian South Pars natural gas field in the
    Persian Gulf with Karachi, Pakistan's main industrial port. Iran
    later proposed an extension of the pipeline from Pakistan into
    India. Although India and Iran signed a memorandum of understanding
    in 1993 for a land-based natural gas pipeline, regional political and
    security concerns continue to block the completion of a feasibility
    study.

    Import Markets

    Apart from natural gas exports, Iran has also discussed
    importing natural gas from Azerbaijan and already imports it from
    Turkmenistan. This is basically for use in Iran's northern areas,
    far from the country's main natural gas reserves in the south.

    In December 1997, Turkmenistan launched the $190 million
    Korpedze-Kordkoy pipeline to Iran, the first natural gas export
    pipeline in central Asia to bypass Russia. According to the 25-year
    contract's terms, Iran will take between 5 and 6 bcm of natural gas
    from Turkmenistan annually, with 35 percent of Turkmen supplies
    allocated as payment for Iran's contribution to building the
    pipeline. Iran's gas imports from Turkmenistan will peak at 8 bcm
    per year.

    Armenia and Iran have agreed to a long-term deal under which Iran
    will supply an annual 1.3 tcf of natural gas to Armenia over 20
    years (starting in 2007) in exchange for electricity supplies from
    Armenia. The two countries will also build an 85-mile gas pipeline
    at a cost of more than $200 million (construction on the pipeline
    began in late November 2004). Armenia is also reportedly keen to
    receive credit from Iran for building hydroelectric plants on the
    Aras River in exchange for electricity supplies to Iran. These deals
    are expected to boost regional trade and cooperation between Iran
    and central Asian states.

    Iran's gas industry now contributes the lion's share to the
    country's fossil fuel basket and it has entered an intense stage of
    development. For more than 40 years, gas has played a secondary role
    to oil. But the growing demand for natural gas in the residential and
    industrial sectors, along with surging export demand, have launched a
    new era. To respond adequately, Iran's gas sector needs investments,
    especially in upstream development, technology transfer, and export
    and import facilitation. With or without foreign investment, Iran
    will be a key gas exporter for decades to come.
