Summary Information

  • Operator: Total
  • Country: Congo
  • Location: 50 miles (80 kilometers) off the Congolese coast
  • Production start:
  • Partners: Chevron (31.5 percent) and Societe Nationale des Petroles du Congo (15 percent)
  • Type: Oil
  • Estimated Reserves: Close to 230 million barrels of oil
  • Production Volume: plateau at 90,000 barrels of oil per day in 2010


  • The Moho Bilondo Field is approximately 50 miles (80 kilometers) off the Congolese coast, in water depths ranging from approximately 1,770 to 2,430 feet (540 to 740 meters).
  • Insulated umbilicals and flowlines will bring the oil to the floating production unit (FPU), from which it will then be exported via a new 16-inch, 80-kilometre pipeline to the Total-operated Djeno Oil Terminal.
  • The Moho Bilondo “Phase 1 bis” project includes wells tied back to the existing floating production unit


  • Stolt Offshore:
    • Engineering, procurement, supply and installation of umbilicals and flowlines
    • Engineering, procurement, installation and commissioning of a 16” diameter export pipeline
  • FMC Technologies: 12 subsea trees and associated structures, manifolds, production control and intervention systems
  • Technip: Project management, engineering, supply, fabrication and installation of:
    • 230 kilometers of rigid pipelines,
    • 23 kilometers of flexible pipes,
    • 50 kilometers of umbilicals,
    • 50 subsea structures as well as various other structures and rigid jumpers and the installation of client-supplied manifolds and pumps, control system components and multiphase jumpers.
    • Project management, detail engineering, procurement and supply for the modifications of the Alima FPU, with two new subsea tie-backs
  • Hyundai Heavy: engineering, procurement, supply, construction, and commissioning for
    • A floating production unit (FPU)
    • A tension leg platform (TLP)
  • OneSubsea: Multiphase Pump Station with 2 off 3.5 megawatt high-boost pumps, a power and control module, a power and control umbilical, and PhaseWatcher Subsea Multiphase Flow Meters with Vx technology for pump control
  • JDR Cable Systems: Design, manufacture and test two Electro Hydraulical umbilicals with air powered reeler and sheaves
  • Aker: Pusnes Offloading System

  • Mobim and Bilondo are buried under 1,100 to 1,200 meters of unstable sediment. They were formed about 20 million years ago, when the Congo River disgorged large quantities of sediment rich in organic debris. The sediment spread in successive waves over the deep ocean floor, and the organic matter was gradually transformed into viscous oil. Bilondo's oil is trapped in a series of small sand channels, while Mobim's is contained in two discrete reservoirs. A configuration like this, with discontinuous, composite pockets, is a headache for geologists, who have a hard time predicting how the fluids will circulate during production. In addition, the oil in Mobim and Bilondo is the product of different source rocks, and not equally mature. Bilondo's is seven times more viscous than Mobim's. By using very fine-scale geological models and leveraging our experience in the Gulf of Guinea, we were able to overcome most of these problems
