The Talinga Orana Gas Gathering Station was installed and commissioned by contractor MAN Energy Solutions and Monadelphous and connects onshore CSG fields to the LNG export hub.
The TOGGS is a dual train gas gathering station around 30 kilometres south west of Chinchilla and consists of two electric motor driven RB56 compressor trains. It was designed to maximise production from the Talinga and Orana gas fields in the Surat Basin.
The Talinga gas field, with 570 petajoules of 2P reserves, is co-owned and operated by Origin Energy and lies within production license PL226. There are more than 111 CSG wells across the field and it produces at around 98 terajoules of gas per day.
The Orana gas field is a new development with 2P reserves of approximately 337 petajoules of gas, according to QLD government documents. The field lies within Production License PL215.
A third field, known as Orana North is also under development by Origin. This field is the larger of the fields with a 2P reserve of 501PJ of gas and sits in PL272.
Monadelphous was awarded the complete fabrication and construction package for the TOGGS project including civil, structural, mechanical, piping, and electrical and instrumentation works.
It then contracted MAN Energy Solutions for installation and commissioning.
As of this month the TOGGS was brought online.
"The station adds important versatility to the Australia Pacific LNG upstream asset portfolio and ability to bring gas to market," contractor MAN Energy Solutions said in a short statement.
APLNG production was a saving grace for Origin Energy as free cash flow increased over the financial year ending June 30, by as much as $105 million.
Origin chief Frank Calabria said in the financial report that "strong field performance" was a key reason behind the increased cash flow.
Over the final quarter APLNG shipped its 500th cargo of LNG.
Origin was trading down about 1.5% in afternoon trade at $4.73 per share.
