Liwan 3-1 Gas Field

Operator: Husky
Country: China
Location: South China Sea
Production start: 2014
Partners: CNOOC
Type: Gas
Estimated Reserves: estimated contingent reserves of between 4 trillion and 6 trillion cubic feet of gas
Production Volume: Peak gas sales are expected to rise towards a range of 400 to 500 mmcf/day (gross)

Liwan 3-1, is located about 300 kilometres southeast of Hong Kong
The project consists of three fields: Liwan 3-1, Liuhua 34-2 and Liuhua 29-1, which share a subsea production system, subsea pipeline transportation and onshore gas processing infrastructure
Husky and CNOOC have signed an agreement specifying the key principles of cooperation for funding and operation of Liwan 3-1.
- Husky will operate the deepwater portion of the Liwan 3-1 field, including development drilling and completions, subsea equipment and controls, and subsea tie-backs to a shallow water platform.
- CNOOC will operate the shallow water infrastructure, including the platform, subsea pipeline to shore and the onshore gas processing plant
With a total length of 260 kilometers, a pipeline will link the Liwan gas platform to China National Offshore Oil Corporation’s (CNOOC) Gaolan gas plant
