Activity Description

The Thylacine field is located approximately 70km offshore from Port Campbell, Victoria in approximately 100m of water and the Geographe reservoir is located approximately 55km offshore in 85m of water.Raw gas including condensate from the Geographe and Thylacine fields are processed at the onshore OGP located approximately 7km northeast of Port Campbell. The current approved field development plan [167] has an end of field life of 2026. Over this period the fields are expected to supply approximately:
555 billion cubic feet of raw gas, equivalent to 505 petajoules of sales gas,
7 million barrels of condensate; and
1 million tonnes of Liquefied Petroleum Gases (LPG).
Actual end of field life and recovery of resources is dependent on a number of factors including operational performance and possible future field development which may lead to the end of field life extending beyond 2026.
This EP covers all the offshore operations activities for the Otway gas development including;
four producing Thylacine gas wells (TA-1, TA-2, TA-3 and TA-4) and the plugged and suspended Thylacine 1 exploration well;
one producing Geographe well (GEO-2) and two plugged and suspended Geographe wells (GEO-1 and GEO-3), completion of GEO-3 is planned at a later date;
the unmanned Thylacine-A production platform, supporting the wellheads and topsides facilities required for production metering from the combined Thylacine wells; and
offshore pipeline system consisting of a 500mm (20 inch) production pipeline and a 100mm mono ethylene glycol (MEG) piggyback service pipeline from the platform to the shore crossing at the Port Campbell Rifle Range, situated to the west of Port Campbell.
Umbilical between Thylacine and Geographe transporting MEG, chemicals (methanol, scale inhibitor) and hydraulic fluid to Geographe in addition to power and controls.
