Bayu-Undan lies in the Timor Sea, 500km offshore of Darwin and 250km south of East Timor. The fields are located on 160km² in 80m of water.
The operator is ConocoPhilips, which has a 56.27% stake, its partners being Eni (12.04%), Santos (10.64%), Inpex (10.53%) and Tokyo Electric Power and Tokyo Gas (10.08% each).
Discovery
Bayu was discovered in early 1995, when the Bayu-1 well intersected a 155m gas/condensate column, at a depth of 897m. This tested 2.54m³/day of gas and 5,250bbl of condensate. The follow-up well, Bayu-2, tested 991,000m³/day of gas and 2,000bbl of condensate from a 52m interval.
In July 1995, Undan was discovered 10km north-west of Bayu, where a 139m gross hydrocarbon column tested 1.6 million m³/day of gas and 3,900bbl condensate/day. The total recoverable field of reserves is 350-400 million barrels of hydrocarbon liquids and 3.4TCF of gas.
The 25x15km field will require approximately 26 wells over its lifetime to produce the reserves, 16 of which - including the first high-angle well in the Timor Sea - will be required before start-up. The field life is estimated to be 25 years. Commercial production began in April 2004, delivering 115,000 barrels per day of condensates and LPG.
The project has been developed in two phases. The US$1.8b n first-stage gas-liquids phase involved the production and processing of wet gas, the separation and storage of condensate, propane and butane, and the re-injection of dry natural gas back into the reservoir. This phase also involved the construction of a remote Wellhead platform, a Drilling, Production and Processing platform and a Compression, Utilities and Quarters platform. The recovered liquids are piped to a Floating Storage and Offloading (FSO) facility.

I was involved in this project during Hook up & Commissioning (2003 - 2004) and maintenance shutdown (2005). Mostly Filipino craftmen were hired by Conoco.
