South Pars/North Dome Gas-Condensate field

[10] The field is a part of the N-trending Qatar Arch structural feature that is bounded by the Zagros fold and thrust belt to the north and northeast.

[17] The field is rich in liquids and yields approximately 40 barrels (6.4 m3) of condensate per 1 million cubic feet (28×10^3 m3) of gas.

[19] In 2005, QatarEnergy became worried the North Dome's reserves were being developed too quickly, which could reduce reservoir pressure and possibly damage its long-term production potential.

In early 2005, the government placed a moratorium on additional development projects at the North Dome pending a study of the field's reservoirs.

[21] The 2005 moratorium by Qatar and the subsequent extension of that raised some questions about the actual proven reserves in Qatari side of the field.

[23] On 29 October 2007, Qatargas CEO Faisal Al Suwaidi stated that the 5-year moratorium on new North Field gas development projects, imposed in 2005, could be extended to 2011 or 2012.

[20] The exploration moratorium was lifted by Qatar in April 2017 with the announcement of a new gas project in the southern part of the field.

Field development has been delayed by various problems - technical (i.e., high levels of mercaptans and foul-smelling sulfur compounds), contractual issues and, recently, politics.

Each standard phase is defined for daily production of 1 billion cubic feet (28 million cubic metres) of natural gas, 40,000 barrels (6,400 m3) of condensate, 1500 tonnes of liquefied petroleum gas (LPG) and 200 tonnes of sulfur, however some phases have some different production plans.

[26] Each of the phases is estimated to have an average capital spend of around US$1.5 billion, and most will be led by foreign oil firms working in partnership with local companies.

[27] Development of a South Pars phase by the Norwegian Statoil company has become infamous after extensive report of misconduct and bribery to the Horton Investments, an Iranian consultancy firm owned by Mehdi Hashemi Rafsanjani, son of former Iranian President Hashemi Rafsanjani.

[28] The government of Mr Ahmadinejad, who came to power in 2005, has favoured local firms over foreign companies in the energy and other sectors.

[31] As at 2012, some 400 Iranian companies were taking part in the development of the South Pars gas field through supplying equipment to related projects.

The most important impact of delays and lower production in Iranian side would be migration of gas to the Qatari part and a loss of condensate yield due to decreased field pressure.

With falling oil and associated gas production, and depletion of the Khuff reserves, developing the North field became imperative.

Phase 1 involved installing production, processing, and transport facilities for 800 million cubic feet (23 million cubic metres) of natural gas per day to serve local utilities and produce 5,000 tons per day of propane, butane, gasoline, and naphtha.

In 1988, a firm of international consultants presented a plan to QP for developing domestic projects to utilize Qatari gas.

Here are a number of milestones: Subsequent phases of the North field development provided feedstock to LNG plants at Ras Laffan Industrial City.

[1] In order to monetize North Dome's vast resources of gas and liquids, Qatar has undertaken ambitious plans for establishment of the world's biggest LNG and GTL industry.

Based on the massive gas resources of the field, Qatar is developing the world biggest LNG export facilities in order to reach the capacity of 77 million metric ton per year by 2012 (see table below).

[49] The project is under construction and will be the world's largest GTL plant which will have the capacity of 140,000 barrels per day (22,000 m3/d) of middle distillates and significant quantities of LPG and condensate.
