Description

Castrol Transaqua? HT2 is a water-based hydraulic control fluid specifically formulated for use as the control medium

in 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.

Transaqua? HT2 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 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 -30oC (-22oF) to 180oC (356oF).

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

Tested according to OSPAR requirements and is registered for use offshore in the UK, Netherlands and Norway.

Rigorous environmental testing has been completed in many geographies worldwide.

Has an identical formulation to the field proven Castrol Transaqua HT with a replacement dye and ultra violet

tracer.

Contains a leak tracer to allow rapid detection of subsea leaks either visually or using a dedicated ROV

mountable leak detection sensor.

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 Transaqua range and most

other water-based subsea control fluids.

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.
