6.3 Papua New Guinea

The representative analyses discussed above do not include an analysis of CO2 transport and storage in potential storage sites in Papua New Guinea (PNG). The principal reason for this is that current natural gas developments in PNG have very low or negligible CO2 emissions.

The PNG LNG project currently being developed will tie together sources of natural gas in the Juha, Hides, Angore gas fields, and the gas associated with the Kutubu, Agogo, Moran and Gobe oil fields (Oil Search Annual Report 2009). With CO2 representing just over 5% of the volume of raw gas, Juha has the by far the highest CO2 content of all the sources of gas in the LNG project. Juha is the most remote of the sources of gas, is not planned to be tied in until later in the life of the LNG project and is expected to produce CO2 at rates that will be very small in comparison to the volume of natural gas produced. Therefore, the small rate of CO2 production is not expected to jeopardise the gas specifications for LNG production. We understand that, for these reasons, there are no plans to extract CO2 from any gas developments linked to the LNG project. That includes any CO2 from Juha. For the same reason, it is unlikely that sufficient CO2 would be available from existing gas developments for enhanced oil or gas production in the existing oil or gas developments in PNG.
