Project Profile
Value: US$10 billion
Location: Barzan Field (North Gas Field), Qatar
Peak Production: 700,000 million cubic feet per day (mmcfd)
Block award: 6th January 2011
Start-up Year: -
The 6.2-billion cubic feet a day development project will be implemented in three phases and will entail the construction of six gas processing trains over eight years. The projects initial phase will supply domestic gas to meet Qatar\'s infrastructure and industry growth and will involve the construction of two onshore gas processing trains by the end of 2013, with a combined capacity of 1.7 billion cf/d, along with gas sweetening units, amine recovery units, storage and loading facilities as well as offsites. The project will have four EPC deals. The scope of works includes three unmanned offshore wellhead platforms, riser tower platforms, power supply to existing offshore platforms and subsea intrafield pipelines. The package also includes two 34-in, 72km-long wet gas pipelines running to the shore, two 28-in intrafield pipelines of six kilometres and nine kilometres respectively, and two 34-in onshore gas export pipelines to the inlet gas reception facilities.
The second phase aims to deliver 2 billion cf/d of gas from the North field for domestic consumption, in addition to the current Barzan project, and the third up to 2.5 billion cf/d, bringing the total to 6.2 billion cf/d. It is unclear when the second phase will be launched. Qatar has imposed a moratorium on further upstream development of the field since 2005 until at least 2015 when technical studies of reservoir depletion are expected to be completed. The Barzan project was drawn up after ExxonMobil decided not to go ahead with the proposed greenfield GTL project at Ras Laffan because of spiralling project costs. In addition to supplying gas for power generation, ExxonMobil plans to build a multi-feed ethane cracker from the gas and NGL to be produced under the Barzan development.
