COMPLETION SOLUTIONS CheckStream® Chemical Injection System Optimize Flow Assurance through Chemical Management ® The Halliburton CheckStream system is a downhole chemical injection system featuring a dual redundant check valve installed and protected by an industry-standard mandrel. • High pressure and temperature ratings of 15,000 psi differential and 392°F (200°C) for HPHT applications • Configurable for multi-point, single control line injection applications The CheckStream system provides precise wellbore chemical management, maintaining flow assurance and continuing production without costly intervention. The dual redundant check valve allows delivery of chemical fluids to the wellbore while simultaneously preventing wellbore fluids and gas from entering the control line and migrating to the surface. CheckStream Mandrel Applications include completions where chemicals are needed to be injected downhole to prevent: The CheckStream mandrel includes a profile for burst disc installation. Two types of chemical injection mandrels are available. • Scale • The deep-set mandrel features a one-piece machined design for use in deepwater or critical applications. The deep-set mandrel utilizes the same design criteria as the permanent downhole gauge mandrel • Asphaltines • Emulsions • Hydrates • Foaming • Extensive qualification testing performed to achieve highest reliability • The welded pup joint nipple mandrel is designed for use in low pressure, shallow-set, non-deviated well applications • Paraffin • Stress Corrosion • Cracking Corrosion Benefits HAL39921 • Maintains flow assurance • Optimizes production performance • Helps reduce costly intervention ® CheckStream One-Piece Mandrel CheckStream Check Valve Features • Dual redundant checks (hard and soft seats) • Field-installable burst disc with selectable ranges • Cracking pressures up to 1000 psi • Wide range of flow rates up to 8 gallons per minute (GPM) • Industry-proven testable, dual metal-to-metal FMJ seal connectors CheckStream dual redundant check valve configurations include a wide range of flow, variable cracking pressures and different connection sizes providing a variety of options to best suit well conditions. Connections to the check valve are pressure testable, dual metal-to-metal seal FMJ connectors delivering added protection compared to standard single metal-to-metal seal connections. COMPLETION SOLUTIONS The control 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.

CheckStream Lines and Cable Protectors Hydraulic control lines and 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. HAL37644 CheckStream valves endured thousands of pressure and temperature cycles using liquid and gas test mediums. Long-term endurance testing was also performed helping ensure optimal valve performance throughout the life of the well.
