CheckStream™ Chemical Injection System - Halliburton

COMPLETION SOLUTIONS
CheckStream Chemical Injection System
Optimize Flow Assurance through Chemistry 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 chassis.
The CheckStream system provides precise wellbore chemistry
management, optimizing flow assurance and enhancing
production. 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.
Applications
Include completions where chemicals are needed to be injected
downhole to prevent:
• Scale
• Asphaltines
• Emulsions
• Hydrates
• Foaming
• Industry-proven FMJ testable dual metal-to-metal
seal connectors
• High pressure and temperature (HPHT) ratings of
15,000 psi differential and 200°C for HPHT applications
• Configurable for multi-point, single control line
injection applications
• Extensive qualification testing performed to achieve
highest reliability
CheckStream Mandrel
The mandrel includes a profile for burst disc installation. Two types
of chemical injection mandrels are available.
• Deep-set nipple mandrel features a one-piece machined design
for use in deep water or critical applications. The deep-set nipple
mandrel utilizes the same design criteria as the permanent
downhole gauge mandrel
• Welded pup joint nipple mandrel is designed for use in low
pressure, shallow set, non-deviated well applications
• Paraffin
• Stress Corrosion
• Cracking Corrosion
Benefits
• Optimizes flow assurance and production performance
• Helps reduce costly intervention
Features
• Subsea, platform and land applications
• Dual redundant checks (hard and soft seats)
• Field-installable burst disc with selectable ranges
• Variable cracking pressures available
• Wide range of flow from 0.02 gallons per minute (GPM)
up to 10 GPM
CheckStream TM One-Piece Mandrel
CheckStream Check Valve
The 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.

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.
The control lines can be provided bare, encapsulated with other
lines, or with tubing encapsulated conductor (TEC) line. Lines are
supplied fluid-filled, flushed and filtered to the required
NAS standard.
Standard cast or pressed steel cable protectors are used to secure
the control lines while running in the hole.
Inconel is a registered trademark of Huntington Alloys.
Installation Services
Multi-line spooling is provided as a standard service, 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
technicians, is also supplied as required.
Multi-Line Spooling Operations
Pumping Units
HAL37646
CheckStream valves endured tens of thousands of pressure and
temperature cycles using liquid and gas test medians. Long-term
endurance testing was also performed ensuring valve optimal
performance throughout the life of the well.
