Castrol Brayco Micronic SV/4

The new SV/4 enhanced product will replace SV/3 and SV/B, and deliver improved environmental performance.

Castrol Brayco Micronic SV/4 is a synthetic hydrocarbon control fluid specifically formulated for use as the control medium in closed-loop surface and subsea production control systems. The fluid incorporates all the features required for operation throughout the control system including Sub Surface Safety Valves (SSSV) and intelligent well completions.

Castrol Brayco MicronicTM SV/4 has been developed and qualified using rigorous industry and equipment manufacturers quality standards. Qualification testing was carried out in accordance to Industry Standard API 17F Annex C (Rev4, Nov. 2017) requirements.

• Designed for use in all conventional and high-pressure, high-temperature applications (according to API 17F Annex C, Rev4, Nov. 2017).
• Can operate over a temperature range of -40ºC (-40ºF) to 200ºC (392ºF).
• Suitable for use within Electro-Hydraulic Multiplex (EH-Mux) or direct hydraulic control systems.
• Designed for use throughout the entire production and workover control systems, covering Topsides and Subsea applications: both open water and well bore; and Downhole from the control of a single SSSV through to complex intelligent well completions.
• May be used as compensation fluid in systems such as subsea manifold valves, or in equipment requiring lubrication such as subsea HPU .

Seal Materials to be Avoided Ethylene Propylene rubbers (EPR, EPDM) are not compatible with Castrol Brayco Micronic SV/4. These materials must be changed out from equipment to be used with Castrol Brayco Micronic SV/4.

Castrol Brayco Micronic SV/4 is compatible with many materials commonly used in the construction of modern production subsea control systems. As with any fluid, a complete materials review should always be carried out before using Brayco Micronic SV/4. Metals to be Avoided Being a non-aqueous medium, galvanic corrosion is minimized and hence Castrol Brayco Micronic SV/4 is suitable for use where a wide variety of metals are used within the control system.
