Oil and gas company Pertamina and its partners are to invest up to $40bn in the Natuna gas field project, offshore Indonesia.

Partners ExxonMobil, Total, Petronas and Pertamina are engaged in discussions about whether to develop the field at full capacity or split it into several stages.

The companies also intend to seek government incentives to develop the project, which could take up to ten years for production to start.

The East Natuna prospect has approximately 46 trillion cubic feet of gas reserves and contains 71% carbon dioxide, reports Reuters.

The companies could transmit the natural gas through pipelines or liquefy it for exports.
