Subsea Boosting Systems

Increase well flow and recoverable reserves

Energy Consumption Reduction

Reduce energy consumption by 62% (0.27 TW.h) compared with gas lift (for typical 4- to 8-well tieback, average-sized single-pump station, differential pressures up to 2,900 psi, and 95% uptime over 10 y)

Emissions Reduction

Lower CO2e emissions by 62% (131,000 metric tons) compared with gas lift (because of lower energy consumption; for typical 4- to 8-well tieback, average-sized single-pump station, differential pressures up to 2,900 psi, and 95% uptime over 10 y)

Size Reduction

Minimize footprint with the most compact and space-efficient artificial lift solution

Subsea boosting principles

Subsea pumps boost production and recovery by lowering wellhead pressure to increase the bottomhole drawdown. In addition, they boost the pressure at the outlet of the pump, adding energy and creating a significant impact along the entire fluid journey from the reservoir to the processing facilities.

Since the pumps were introduced in the 1990s, significant technical advances have increased capacities, power, and differential pressures while expanding the envelope of operations to deeper water and greater tieback distances.

Increase Recovery and Accelerate Production
Lower wellhead pressure to improve oil recovery; boost early revenue with 20%–200% higher flow rates.
Improve Flow Assurance
Mitigate slugging with more benign flow regimes and facilitate hydrate and wax management because of heat transfer from the pump and motor.
Lower Capex and Opex
Simplify subsea infrastructure, reduce energy consumption, and improve system uptime (via quicker startup and fewer interventions).
Enhance Production Management
Maintain production from weaker wells without any adjustments to the stronger ones.
Facilitate Heavy Oil Production
Produce oil with viscosities up to 30,000 cP.
Produce from Otherwise Unavailable Fields
Compensate for the pressure drop over long tieback distances with higher pressures at the pump outlet.

A comprehensive offering for diverse flow regimes

With >4 million running hours accumulated, OneSubsea boosting pumps are inherently robust and wear-resistant, suitable for use with fluids containing sand particles—a common occurrence in most subsea production systems.

All pumps are configured with an electric motor mounted on top and the pump section at the bottom, both within a vertical cartridge that is fully encapsulated in a pressure housing. The optimized compact design enables subsea installation and retrieval by light vessels.

Depending on how a field develops, any pump type can be fitted into the standardized subsea interface, giving you the option to replace one pump with a different type to meet the requirements of your field throughout its life.

An integrated approach

Total system solutions ensure that all risks are identified and mitigated in the early stages of field development planning. These solutions include all the equipment needed to operate the pumps during startup, shutdown, and normal flowing conditions; they are combined with operational support to provide complete system availability.
