Iran's Pars Oil and Gas Company (POGC) commenced underwater pipelaying operations for Phases 20 and 21 of the massive South Pars gas field located on the Iranian border with Qatar in the Persian Gulf, project manager of the phases said Wednesday.
Once completed the 65-mile (105-kilometer) long pipelines will deliver sour gas recovered from the phases to the onshore refining facilities in Assaluyeh, south of Iran, said Alireza Ebadi.
So far 25 miles (40 kilometers) of Phase 21 underwater pipes have been laid while a record has been set for laying 171 pipes in a day's work during the operation, he said.
Platforms of the phases, due to be completed by mid-September, will be installed in their places by the POGC once the pipelay operations are over.
Phases 20 and 21 of South Pars gas filed are being developed for production of 1.766 million cubic feet per day (MMcf/d) or 50 thousand cubic meters per day (Mcm/d) of processed natural gas for domestic consumption, a million tons a year of ethane for use by petrochemical plants, 1.05 million tons a year of high-quality liquefied gas for exports and 75,000 barrels a day of condensate.
South Pars, divided into 29 development phases, holds 1,412.43 trillion cubic feet (Tcf) or 40 trillion cubic meters (Tcm) of natural gas, or 21 percent of world’s total gas reserves, and 50 billion barrels of condensate.
South Pars covers an area of 3,745 square miles (9,700 square kilometers), 1,429 square miles (3,700 square kilometers) of which are in Iran’s territorial waters in the Persian Gulf. The remaining 2,317 square miles (6,000 square kilometers) are situated in Qatar’s territorial waters.
The gas field is estimated to contain a significant amount of natural gas, accounting for about eight percent of the world’s reserves, and approximately 18 billion barrels of condensate.
