Pergas Projects 2004 - 2005 South Pars Phases 6, 7 & 8

The development project for phases 6, 7 & 8 has been designed to produce 104 MMscm/d of gas from the reservoir that is going through its final construction steps.


The objectives of the development of phases 6,7 & 8 are as follows:


  • Daily production of 104 MMscm/d of sour and dry gas.

  • Daily production of 158,000 bl of gas condensate per day.

  • Annual production of 1.6 million tons of liquid gas (propane and butane) "LPG" for export.

  • The sour gas produced in these phases is transferred to Aghajari oil field in Khuzestan province via a 512-kilometre pipeline to be injected into the oil wells to enhance the recovery coefficient of the field.


Offshore Facilities:


  • Three production platforms with 30 gas wells.

  • Three 32" submarine pipelines for transferring gas to the onshore refinery, length of each approximately 105 km.

  • Three 4.5" pipeline for transferring glycol solution.

  • One Single Buoy Mooring (SBM) terminal for exporting gas condensate and A 5.4 kilometre 30" pipeline for transferring gas condensate to the SBM.


Onshore Facilities:

Units for receiving and separating condensate from gas, gas dehydration unit, gas dew point regulating unit and liquid gas recovery, gas compression unit, liquid gas treatment unit, gas condensate stabilization unit, and Glycol solution concentration unit for being dispatched to the offshore facilities. In July 2000, the contract for developing phases 6, 7 & 8 of South Pars gas field was awarded to Petropars and the first stage of this project and came to fruition in early 2008.

Gas Sweetening Project Phases 6, 7 and 8 Refinery with respect to the projects carried out to meet the domestic gas consumption demands, a sweetening plant was constructed adjacent to phases 6, 7 and 8 refinery to sweeten its produced gas.

In this way, four gas sweetening and processing trains sweeten and process 4000 MMscf/d of produced gas, which is either dispatched to the domestic gas network or to the oil fields to be injected into them.


Pergas designed sixteen Separator & KO Drums, these 16 sets were sold to The TIJD consortium of Toyo of Japan, IDRO of Iran, JGC of Japan and Daelim of Korea” whom were all subcontractors in these phases. The total weight of the 16 sets was 365 MT and took 9 months to build and transfer to the project location.
