APPLICATIONS ■ Leak repair and bypass ■ Flow isolation ■ Separation ■ Sensor replacement ■ High-integrity pressure protection

system (HIPPS) ■ Sand filtering ■ Subsea sampling ■ Multiphase metering ■ Water injection pumping ■ Multiphase boosting

ADVANTAGES ■ New technology adapted for existing fields ■ HSE risk minimized ■ OEM choke supplier qualification retained ■ Existing installation tooling used

where practical ■ Existing well barriers retained under

control of the operator, reducing risk ■ Life of field extended

The OneSubsea portfolio of MARS* multiple application reinjection system includes retrofit technology comprising a patented insert design that replaces a retrievable choke insert. The system creates an access pathway to the production flow, which establishes an intrinsically safe flow path and enables various production, processing, and injection technologies to be easily added at anytime during the life of the field—all without the need to modify the infrastructure or field architecture.

A universal interface that enables fitting any process to any well at any time during the field’s life can save considerable costs by reducing infrastructure retrieval, modification and repair operations, and deferred production. The modularity of the MARS system helps operators increase revenue through optimized production and reservoir management.
