Product Data Sheet
Why AQUALINK® HT804F VER2 is the Tier 1 HP/HT Standard
Conventional subsea control fluids are not engineered for the extreme pressures and temperatures encountered in HP/HT wells. AQUALINK® HT804F VER2 is formulated from the ground up for wells exceeding 10,000 psi — with qualification testing to 15,000 psi (1,034 bar) and 160°C — providing the fluid life, brine compatibility and corrosion protection that Tier 1 HP/HT production operations demand. Fluid life is rated at 20 years or more in service.
Features & Benefits
| Feature | Advantage & Operational Benefit |
|---|---|
| Tier 1 HP/HT classification — tested to 15,000 psi and 160°C | Qualified for the most extreme deepwater production well conditions — the highest HP/HT performance classification available |
| ISO 13628-6 approved at 160°C | Meets the international subsea production control system standard — accepted by class societies and subsea equipment OEMs globally |
| FMC approved — PRD-0000021632 rev D | OEM-approved for FMC subsea trees, manifolds and Christmas tree control systems — the most widely deployed subsea production OEM globally |
| Fluid life 20 years or more | Significantly reduces subsea system intervention costs — avoiding the expense of umbilical flushing and fluid replacement over the production life of a deepwater field |
| Compatible with completion brines — Potassium Formate, Calcium Bromide, Zinc Bromide, Calcium Chloride | Tolerates brine contamination without system upsets — critical in HP/HT wells where brine ingress is a common operational risk |
| Superior ferrous and non-ferrous corrosion protection in seawater | Protects subsea control system metalwork across the full range of materials used in deepwater production equipment |
| Fluorescent leak trace dye | Enables rapid identification of system leaks during ROV inspection and surface monitoring — minimising leak detection time and environmental discharge risk |
| Resistant to bacterial and fungal growth | Maintains fluid integrity over 20+ year production system life without biocide treatment — reducing operational intervention requirements |
| Cefas D, NEMs Yellow, EPA approved | Globally compliant — environmentally acceptable for maximum discharge in UK, Norwegian and US regulated waters |
| Filtered to NAS1638 Class 6 in drum | Supplied at cleanliness level required for direct use in subsea control systems — no additional filtration required on receipt |
