Deep water fields represent a significant part of our future in term of oil and gas reserves. As a major Oil and Gas Operating Company, Total has been developing deep water fields for more than 10 years. If West Africa is the major contributor with numerous large and deep projects in Nigeria, Angola or Congo, new areas are emerging worldwide. If deep water developments are real opportunities for increasing level of reserves, they also mean real technological and economical challenges:

  • Going deeper means subsea boosting or flow assurance major issues.

  • Discovering smaller reservoirs brings economical challenges.

  • Facing more and more complex fluids imposes new subsea alternative architectures to deal with.

  • Tackling longer and longer tie backs raises subsea power transmission or flow assurance complex issues.

To face those challenges, the oil and gas industry needs to explore new technological avenues such as for instance all electric systems, subsea processing with gas/liquid or liquid/liquid separation, alternative materials or subsea autonomous intervention capacities with a low cost approach in mind.
