Thylacine/Geographe (Australia)
Gas Projects Commissioning
The Thylacine and Geographe gas fields are located 70 and 55 kilometers, respectively, south of the Victorian coastline. The Thylacine gas field has been developed using an unmanned well head platform (four wells), an export pipeline to shore, and an onshore gas and liquids processing facility at Port Campbell. Gas from the processing plant feeds into the Victorian and South Australian natural gas grids. Condensate and LPG are separated from the gas stream for onshipping to the Geelong oil refinery and local market, respectively.
An inlet compression project in the gas plant has begun and is expected to be
complete in early 2011. The concept select process for the Geographe gas field development is ongoing.
In 2001, the first discovery well in the T/30P permit, Thylacine No. 1, encountered a 277m gas column, directly followed by the discovery of a 233m gas column in the Geographe No. 1 well in the Vic/P43 permit approximately 15 kilometers to the north. This was followed in succession by the Thylacine No. 2 appraisal well on the western flank of the Thylacine gas field.
The Otway Gas Project development was sanctioned in May 2004, and reliable gas
export was achieved in mid 2008.
The Thylacine gas field has been developed using three horizontal wells and a large bore deviated well,
all drilled from an unmanned platform.
It is planned that the Geographe gas field will be developed and tied back to the export pipeline in the near future.
