The development, around 300 km (186 mi) southeast of the Hong Kong Special Administrative Region, takes in the Liwan 3-1, Liuhua 34-2, and Liuhua 29-1 fields. These are being developed via a shared subsea production system, subsea pipeline transportation, and onshore gas processing infrastructure.
Under the $6.5-billion first-stage program, Liwan 3-1 is expected to produce about 250 MMcf/d (7.1 MMcm/d), and increase to about 300 MMcf/d (8.5 MMcm/d) during the coming quarter. Initial sales of condensates and natural gas liquids from the field are expected to reach 10,000-14,000 boe/d.
Liuhua 34-2 will be tied into the Liwan infrastructure during the second half of the year, subject to final approvals. Production from Liwan 3-1 will be offline for six to eight weeks to accommodate the tie-in.
Combined gas output from the two fields of around 340 MMcf/d (9.6 MMcm/d) will be processed at a terminal onshore in Gaolan and sold to the mainland China market.
Once Liuhua 29-1 is tied in during 2016-2017, total gas sales will build to 400-500 MMcf/d (11-14 MMcm/d).
Husky has a 49% interest in the production-sharing contract and operates the deepwater infrastructure. CNOOC has a 51% interest and operates the shallow-water facilities and onshore gas terminal.
