Project Profile
Value: Undisclosed
Location: Block 91-12 (60%) and 91-13 (40%), under Area A of the Australia / Indonesia Zone of Cooperation
Reserves: 3.4 Tcf of gas
Start-up Year: 3Q 2013
The Bayu-Undan offshore gas and natural gas liquids field is located in shallow waters, about 500 km northwest of Darwin. The Bayu field was discovered in 1995 with the Bayu-1 exploration well and the Undan field was discovered later that year with the Undan-1 exploration well. The field is estimated to hold 3.4 Tcf of gas. Participants in the Bayu-Undan joint venture are ConocoPhillips (operator), Eni, Santos, Inpex and Tokyo Timor Sea Resources Pty.
The development of the field proceeded in two phases. The first phase, completed in 2004, consisted in the production of natural gas liquids (propane, butane and condensates). The second phase, completed in 2006, allows the production of natural gas that is conveyed, through a 500 km, 26 inch gasline, to the LNG plant at Wickham Point, Darwin, which has a capacity of 3.5 million tonnes/year. The LNG plant uses ConocoPhillips’ optimised cascade LNG process technology with associated storage and marine load-out facilities. Bayu-Undan consists of a floating storage and offloading facility and three fixed platforms, a remote wellhead platform, and a compression, utilities and quarters platform, which is bridge-linked to a drilling, production and processing platform.
