Background
 
The Iranian South Pars field is the northern extension of Qatar's giant North Field. It covers an area of 500 square miles and is located 3,000m below the seabed at a water depth of 65m. The Iranian side accounts for 10% of the world's and 60% of Iran's total gas reserves. Iran's portion of the field contains an estimated 436 trillion cubic feet.The field is planned to be developed in around 30 phases.There are 10 phases of the South Gasfield gas project that has been put into operation steadily.National Iranian Oil Co. (NIOC) signed a multi-billion dollar dealwith French oil firm Total (TOT) and Chinese state oil company CNPC in July 2017.  The project would require total investment of about $4.8 billion and the first phase of the project will cost around $2 billion.Total is taking a 50.1% stake in the South Pars project. CNPC will own 30% and Iran's Petropars 19.9%.The gas will start flowing into the Iranian market in 2021.The project will have a production capacity of two billion cubic feet per day, or 400,000 barrels of oil equivalent per day including condensate.
 
Brief  Introduction
 
SP11 will be developed in two phases. The first phase, with an estimated cost of around $2 billion equivalent.The development project for phase 11 will be designed and implemented to supply the required sour gas to "Iran LNG" unit and produce associated gas condensates.

Technical Specifications of the Project:

Gas production amounting to 2000 MMscf/d from South Pars Gas Field.

Extraction of 1900 MMscf/d sour gas to feed LNG Plant. 

Production of 80,000 bbl/d of heavy gas condensates.
 
Offshore Facilities:
Two stand alone platforms each equipped with the following facilities:

12 wells for producing 1000 MMscf/d of gas;

Three-phase test separator (gas, condensate and water) for testing the wells;

Two three-phase separators (gas, condensate and water) for water separation;

Water treatment unit for treatment of the water polluted with oil products before being discharged to the sea;

Tripod flare platform for emergency de-pressurizing;

Two 32-inch sea lines, 136 Km. long each, for transferring the gas produced in the platforms to the processing unit;

Two 4.5-inch sea lines for transferring glycol solution to the offshore platforms.

36-inch gas condensate transfer pipeline, 4.5 Km. long and and Single Buoy Mooring (SBM) to load and export the produced condensates.

onshore Facilities:

The slug catcher and condensate-water separators;

Gas condensate storage unit and the equipment for dispatching it to the shore

Mono Ethylene Glycol Regeneration Unit 

Utilities including steam, water and miscellaneous services such as Nitrogen, air, etc.;

Industrial waste water and sanitary water treatment;

Flaring systems for emergency de-pressurizing;

Fire fighting water system (tank, pumps and network);

Control rooms, electricity substations, laboratory, warehouse, workshop, offices, etc.

Gas and diesel fuel system of the processing unit, 

The onshore facilities of the project are to be constructed some 136 kilometers away from the offshore facilities, in Pars Special Economic Energy Zone 2 (PSEEZ-2).
