Overview

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.

Phase 19 has been designed as a single package, with phases 20 and 21 as another. These phases will increase production in the gas field by 530 million cubic feet a day (cfd) of gas and 160,000 barrels of condensate. Sulphur produced will be exported.

It includes the drilling of four appraisal wells, the drilling of 44 development wells, building wellhead platforms, laying a subsea and onshore pipeline, building a gas processing plant.

As of November 2012, this phase of the project was more than 50 per cent complete and commissioning is expected for April 2014.

Phase 19

Offshore facilities:

• 21 wells (including drilling of 15 new wells)
• 4 offshore platforms (two main platforms + two satellite platforms)
• Various pipelines

Gas and input liquids will be processed in the Onshore Processing Unit, producing the following products:

• 50 Million Standard Cubic Metres a Day of refined gas
• 1.1 million tonnes a year of liquefied gas for export
• 77,000 barrels a day of gas condensates for export
• 1 million tonnes a year of Ethane gas to feed the petrochemical plants

Phases 20 and 21

• The construction and installation of two wellhead platforms equipped with a free water knock-out drum, test separator, utilities, access bridges and flare platform
• Drilling of 22 production wells
• Installation of various pipelines
• Construction of a standalone gas treating refinery
• Electricity supply from the projects’ common power plant
