Project Profile
Value: US$6,000 million
Location: Block 29/26, Liwan, South China sea
Area: 2,230 sq km
Water Depth: 1,450 m
Start-up Year: 4Q 2013
The 29/26 block is located in the South China Sea approximately 300 kilometres southeast of Hong Kong and 65 kilometres southeast of the Panyu gas discovery. It covers approximately 2,230 square kilometres. Delineation drilling was completed in 2009 through the drilling and testing of three wells. The deepwater drilling rig West Hercules spud the first appraisal well in November 2008. In August 2009, the West Hercules completed drilling and testing of the third appraisal well. The rig drilled the Liwan 3-1-4 well to a total vertical depth of 3,366 metres below sea level. The well was drilled and tested in a water depth of 1,450 metres.
The results from this well were consistent with those of the other appraisal wells, demonstrating both the quality and consistency of the reservoir. The appraisal program has delineated the field, increasing Husky’s understanding of the recoverable resource, and providing the necessary reservoir characterisation to prepare the plan of development for Liwan field. Husky is proceeding with the front end engineering design (FEED). Currently Husky expects the plan of development will be submitted to partner and regulatory authorities in early 2010. First gas production is targeted to be in the 2013 timeframe.
Block 63/05
In 2008 Husky acquired Block 63/05 in the Qiongdongnan Basin approximately 100 kilometres south of Hainan Island. This 1,777 square kilometres exploration block is located in an area with water depths of less than 120 metres. The block is close to existing and expanding markets, and further augments Husky’s strong lease-hold position in the South China Sea. Existing two dimensional seismic data has been interpreted and Husky plans to acquire new three dimensional seismic data in early 2010.
Development
Development concept of the field is a deepwater subsea gas gathering system, connected by a 100 kilometre pipeline to a central processing platform. The fixed central processing platform is to be located in water depths of 200 metres and is expected to feature a 30,000 tonne jacket and 15,000 tonne topsides. The gas will be moved from the central platform, along a 264 kilometre shallow water pipeline to an onshore terminal in Gaolan port. 10 xmas trees are planned for the project, with two manifolds and associated equipment.
