The WellBoss Integral Chemical Injection Mandrel provides operators with precise wellbore chemical management that is designed to optimize flow assurance and production performance and reduce expensive intervention. The non-welded mandrel features a robust one-piece machined design for use in all applications, including deep water. This mandrel utilizes the same design criteria as the permanent downhole gauge mandrel. The product shown features a single point of injection and based on well environment it may be necessary to stack multiple valves to either establish the necessary volume or to comingle chemicals for optimum protection.

The Integral Chemical Injection multi-valve mandrel is made up to the completion string with the appropriate connection to the surface chemical injection system.

The Chemical Injection valve check valves, provide checks (one hard seat and one soft seat). In the case of dual checks there is the additional redundancy built into the valve. The connection to the chemical injection line uses primary and back-up metal-to-metal ferrules to provide improved sealing and physical strength. Burst disc options are available to allow continual verification of control line pressure integrity during installation. The check valve is available with different cracking pressures, and can be supplied with externally pressure testable connections to reduce rig down-time.

Chemical injection lines are available in 316 Stainless Steel and Inconel® 825 alloy as standard, with tubing sizes and wall thicknesses to suit all applications. The chemical injection lines are typically encapsulated or in a bundled configuration. Lines are supplied fluid-filled, flushed and filtered to the client’s required cleanliness standard. Standard cast or pressed steel cable protectors are used to secure the control lines while running in the hole. Installation Services Multi-line spooling can be provided, including all necessary spooler units, hydraulic slip rings, pumps, filters and sheave wheels. Full pump capability for operations is provided during running in hole and for commissioning the well. A fluid particle counting service, which is carried out by certified offshore technicians, is also supplied as required.
