Qatargas 4

Qatargas 4 (QG4) which started producing LNG in January 2011 completes Qatargas’ planned LNG expansion projects. The project QG4 involved the construction of a new LNG mega-train (Train 7), similar to Qatargas 2 and Qatargas 3 with a production capacity of 7.8 MTA.

The upstream platforms and infrastructure consist of three unmanned platforms (each containing 11 wells) and two subsea pipelines, which are shared with Qatargas 3. Qatargas 4 will produce 1.4 billion standard cubic feet of gas per day delivering LNG and substantial volumes of condensate and LPG, as well as high purity grade sulphur.

QG 4 utilises the same Air Product’s proprietary APX process technology as QG 2 and QG 3, helping to achieve economies of scale and integration not previously possible in the LNG industry. The QG 3 and QG 4 projects were developed and executed by a joint asset development team to capture synergies between the two projects.

The LNG from QG 4 is transported to global markets via a fleet of eight Q-Flex or Q-Max ships (approximately 210,000 – 266,000 cubic metres capacity each) that have been constructed in Korean shipyards. Qatargas’ seventh train will predominantly supply North America, the Middle East and Asia.
