Dual Cartridge Filter Unit

High-flow dual vessel filter system offering flexible configuration, ideal for seawater and produced water treatment across offshore operations.

The Esk Offshore Dual Cartridge Filter Unit is engineered for efficient fluid treatment during wellbore cleanups, gravel pack operations, water injection, and general brine filtration. Designed for flexibility, each stainless steel vessel holds fifty 39” cartridges and supports single, dual parallel, or dual series configurations.

In dual series mode, operators can perform two-stage filtration, using coarse filters first followed by fine filtration. The unit is especially effective when used as a polish filter downstream of diatomaceous earth filters or as a stand-alone solution.

Key benefits include:

  • Flexible in-parallel or in-series flow configurations
  • High flow rate capability up to 18 bbl/min (168 m³/hr)
  • Compact design with a small footprint
  • Easy to operate with minimal training required
  • Highly effective for filtering seawater and produced water using oil absorption elements

Why this unit?

People who know the equipment

The right equipment is only part of the job. Where required, Esk can provide experienced personnel trained across our equipment and operational business lines through our in-house City & Guilds-accredited training school.

That means the people arriving offshore understand the equipment they are there to operate, how it should perform and what is expected of them in the field. A straightforward way to bring the equipment and the operational support together in one package.

I actually think this is a much stronger way to retain the personnel story than giving personnel equal billing as a standalone service. It makes the people another reason to choose the equipment from Esk.
