ExxonMobil and Eni are studying the best way to proceed with the Mamba liquefied natural gas project in Mozambique after December's confirmation that the US supermajor will lead midstream work while its Italian partner will operate the upstream part.

The US giant completed its farm-in to Area 4 — which holds 85 trillion cubic feet of gas resources, including Mamba — just a few months ago, so it is now getting up to speed on the multi-billion-dollar project.
