Jemena Presentation March 16, page-2

Thanks CPMERF, that is interesting.
Jemena's potential nitrogen separation skid is a new one.
Seems nitrogen content in NT is quite high compared to East Coast and CSG fields. Blacktip 8-10% vs east coast 3-4%.

A similar issue may arise once the planned NGP is constructed, connecting gas produced in the Northern Territory to the east coast gas market. If construction of the NGP facilitates additional gas development in the Northern Territory or northern Queensland, any gas moving south of Mount Isa may also require additional processing and additional costs to meet the LNG specification.

Price estimate for large plant at Wallumbilla ~$600 to $1,000 mil
Jemena or APA must install nitrogen removal before Ballera. At what price?

Do you think they would install and process Nitrogen for free?
Another cost above transport tariff?
Ouch.
