The Moho-Bilondo’s frst project phase targeted the Mobim and Bilondo reservoirs that were brought onstream with plateau production of 90,000b/d.

Construction on the second phase, which includes development of northern part of the license, began in 2013 after FEED studies were completed. The project will require an investment of $8 billion and is expected onstream in 2016.
