The Prosperidade bidding process may depend on the progress of unitisation talks between Anadarko, operator of Area 1, and Eni, the operator of Area 4 into which the field extends.

Project approvals from the Italian player are needed as is support from the Mozambique government.

As a result, if Anadarko hits problems that could jeopardise its 2018 start-up date it may look instead to its Atum and Golfinho discoveries, which lie wholly within Area 1, to provide LNG feedstock.
