Brayco Micronic™ SV/3 Synthetic subsea production control fluid Description Castrol Brayco Micronic™ SV/3 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. Brayco Micronic SV/3 has been developed and qualified under a Quality Management System with ISO 9001:2000 Certification and an Environmental Management System with ISO 14001:2004 Certification for Research and Development. Qualification testing was carried out in accordance with ISO 13628-6 Annex C (2006 E) requirements. Application Designed for use in all conventional and high pressure, high temperature applications (according to API 17 TR8). 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 control of a single SSSV through to complex intelligent well completions. Advantages Fully compliant with OSPAR environmental legislation and does not contain any “substitutable” components. Environmental testing has been completed for compliance in other geographies. Has field proven performance, with an operating capability up to 200ºC (392ºF). Maintains corrosion performance with seawater contamination. Tolerant of the high well temperatures encountered by those parts of the control system located at the well bore. Fully compatible and miscible in all proportions with other products in the Castrol Brayco Micronic range. Compatible with a wide range of materials commonly used in subsea control systems (see Tables 3 & 4). More detailed compatibility information is available on request.
