Model B
Weatherford’s splined expansion joint, model B, compensates for
tubing movement resulting from temperature and pressure variations
during production, shut-in, and stimulation in single- and multiple-string
completions. The spline enables the tubing to transmit torque throughout
the stroke length of the tool. A premium seal system maintains the pressure
seal.
Applications
• Single- and dual-string packer installations
• Retrievable and permanent installations
• Deviated and horizontal wells
Features, Advantages and Benefits
• The expansion joint can be pressure tested at the surface to ensure seal
integrity.
• The pressure rating of the joint is compatible with the tubing, providing
pressure integrity during production, shut-in, and stimulation.
• The joint can be pinned in an open, closed, or midstroke position,
enabling selection of the correct stroke before deployment to avoid
damage from overstressing the tubing during production or stimulation.
• The joint design enables it to be stacked for additional stroke
requirements, reducing inventory and saving rig time.
• The full-bore construction provides an unrestricted ID that enables a
maximum flow rate.
• The rugged construction provides high tensile strength for maximum
durability.
Options
• Premium seal stacks are available in materials compatible with fluid
environments.
• Standard EUE, NU, and premium connections are available on order.
• Alternate strokes are available on order.
