AQUALINK® HT804F VER2 — HP/HT Subsea Production Control Fluid
AQUALINK® HT804F VER2 is Quaker Houghton's ready-to-use, biodegradable water-glycol subsea hydraulic control fluid — formulated to meet Tier 1 HP/HT requirements for wells with reservoir pressure from 10,000 to 15,000 psi (689 to 1,034 bar) and temperatures up to 177°C (350°F). It is designed for direct and multiplex electro-hydraulic control systems operating over very long distances, providing optimum reliability, thermal stability, improved lubricity and fast hydraulic response times.
Supplied through Orbit Industrial as an authorised Quaker Houghton distributor across Cape Town, Saldanha Bay, Durban and Port Elizabeth. Available in 209L drums and 1,000L IBC. Available by request for quote only — not available for direct checkout.

Product Data Sheet
Why AQUALINK® HT804F VER2 is Built for HP/HT Subsea Service
Conventional subsea control fluids are not engineered for the extreme pressures and temperatures encountered in HP/HT wells. AQUALINK® HT804F VER2 is formulated for wells with reservoir pressure from 10,000 psi up to 15,000 psi (689 to 1,034 bar), with thermal stability up to 160°C and a well temperature rating of up to 177°C (350°F). Used neat, it offers low viscosity, high lubricity and consistent performance across long-distance electro-hydraulic control umbilicals.
Features & Benefits
| Feature | Advantage & Operational Benefit |
|---|---|
| Tier 1 HP/HT formulation — 10,000 to 15,000 psi, up to 177°C | Qualified for demanding deepwater production well conditions, both conventional and high-temperature |
| Ready-to-use, biodegradable water-glycol formulation | Environmentally acceptable for maximum discharge; exceeds US-EPA toxicity requirements as specified in NPDES permit for subsea control fluids |
| Thermal stability up to 160°C | Maintains performance in high-temperature subsea production environments |
| 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 |
| Excellent ferrous and non-ferrous corrosion protection, even in the presence of seawater | Protects subsea control system metalwork across the full range of materials used in deepwater production equipment |
| Resists glycolic and hydrochloric acid | Maintains fluid integrity in the presence of common well-treatment chemicals |
| Resistant to bacterial and fungal growth | Maintains fluid integrity over an extended service life without biocide treatment |
| Fluorescent leak trace dye | Enables rapid identification of system leaks during ROV inspection and surface monitoring — minimising leak detection time and environmental discharge risk |
| Fully compatible with current water-based subsea control fluids | Simplifies system topping-up and fluid transitions on existing installations |
| D rating with Cefas (UK); Yellow rating with Add Novatech (Norway) — no sub warnings | Environmentally compliant for discharge under UK and Norwegian regulated-waters frameworks |
