Iran’s Pars Oil & Gas Company is exploring and developing the offshore South Pars field, which borders with Qatar’s North Dome gas field in the Gulf, about 100km from the country’s southern coastline. The South Pars/ North Dome gas field is 9,700km squared in size. South Pars sits within Iran’s territorial waters and the field is 3,700 sq km in size, with proven gas reserves of 350 trillion cubic meters, which is 6 per cent of the world total and half of Iran’s total reserves.

Output from phase 7 of this multi-phase project will be used mainly for the National Iranian Oil Company’s LNG plant. Part of the output will also be pumped into the domestic gas network for usage in petrochemical projects and for reinjection in order to replenish the oil fields.

In this phase a liquid processing plant is being built. Work includes:

  • Slug catcher / HP separators
  • Condensate stabilisation (3 trains) and backup
  • MEG regeneration unit / sour water stripper
  • Flares / blowdown / burn pit system / utilities and offsite drain system
  • Relevant technical buildings together with central control building, laboratory and telecommunications building
  • Relevant roads and paving
  • Power generation / steam generation / fuel gas system
  • Instrument and service air system / nitrogen generation system
  • Sea water intake and outfall / waste effluent disposal
  • Desalination / water polishing / potable water / cooling water
