Description

  • 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
