Definitions
- This invention relates to hydraulic fluids, and in particular, but not exclusively, to hydraulic fluids for use in the offshore oil and gas industry.
- BOP Blow-Out Preventor
- the Blow-Out Preventor (BOP) stack is in simple terms, a hydraulically operated safety device that can shut down the well if a gas pocket or oil is discovered (a blow out) .
- the unit works by hydraulic pressure that can be used to seal the gap between the drill string (which turns the head of the drill and connects to the drilling rig) by either forming a seal against the drill string or slicing through the drill string in more dangerous situations.
- the sealing and slicing operation is conducted by hydraulic pressure which forces large hydraulic rams to close; the fluid is then released to sea to relieve the pressure after operation.
- the BOP Stack and hydraulic control pods that are on the seabed (or sometimes on board the rig if drilling in shallow water) are connected by a hydraulic hose
- the hydraulic system has a large hydraulic fluid reserve tank on board and as the fluid is pressurized and then dumped to sea, the fluid is removed from the reserve tank.
- Type-One BOP hydraulic fluid which is an aqueous hydraulic fluid concentrate, minus the water (and antifreeze if required) .
- This type of water based hydraulic fluid is typically a premixed version of the BOP Fluid mentioned above, sometimes with additional antifreeze and stability additives as required.
- This premixed fluid is used to produce oil remotely via a system whereby a subsea hydraulic control system is placed on the wellhead and linked back via a hydraulic umbilical to the producing asset (fixed platform, floating unit or to .land) .
- the system is similar in many ways to the BOP system although in this case the functions at the wellhead control the flow of oil and other production related functions and typically use much smaller valves with greater tolerances and greater need for stability, fluid cleanliness etc.
- the umbilical hydraulic line can be of varying lengths from a few kilometers to several hundred kilometers.
- fluids are based on the same technology as the other fluids described above and usually comprise of the base Type Two Production Control Fluid described above with added thickening agents to match the ISO hydraulic oil in use.
- Typical performance requirements for offshore hydraulic fluids include
- Lubricity it is important that a water based hydraulic fluid has sufficient lubricity to allow moving surfaces (such as metal to metal contacts within valves) , to slide without sticking or wearing outside of acceptable limits.
- Corrosion Protection it is important that a water based hydraulic fluid has sufficient corrosion protection to protect the metals in the system from corrosion, especially if moderate seawater ingress is likely.
- Stability additives it is important that a water based hydraulic fluid has sufficient stability to ensure the fluid does not separate in service. The level of importance of this depends on the application as some systems are very prone to such issues. If a product does not have sufficient stability in its own right, it is common to use some form of chemical additive that will ensure the product does not separate.
- Biocidal Protection it is important that a water based hydraulic fluid has sufficient biocidal protection to prevent excessive growth of fungus and bacteria within the hydraulic fluid medium.
- Antifreeze Protection it is important that a water based hydraulic fluid has sufficient antifreeze protection to allow the product to be used in cold conditions .
- Viscosifiers Some fluids may need to have their viscosity modified to match a certain technical profile, this would involve adding additives to increase or decrease the viscosity of the product.
