Subsea Processing

Definition - What does Subsea Processing mean?

Subsea Processing is a solution used to improve the field economics while maximizing the recovery, increasing the production and reducing costs. It has helped to revolutionize subsea separation and subsea re-injection or boosting, and thus revolutionizing offshore developments all over the world. Subsea Processing is the only solution to the fields that are located in harsh conditions, where the extreme deepwater situation poses risks to the processing equipment. Subsea Processing can be considered as an emergent application that increases the production from marginal and mature fields.

Petropedia explains Subsea Processing

Subsea Processing surrounds numerous other processes that help to reduce the complexity and cost of developing an oil field at an offshore location. The process includes various operations such as:

  • Subsea water removal and disposal or re-injection.
  • Single and multi-phase boosting of fluids.
  • Solid and sand separation.
  • Liquid or gas boosting and separation.
  • Gas compression and treatment.

Subsea Processing can be used for a number of reasons which include the increase in field recovery, thus increasing profit. It contributes to the flow assurance and management that improves the efficiency of risers and flowlines. It also improves the marginal fields to economically applicable developments. Innovative processing can improve the rate of production.
