About
The Permanent Inflatable Bridge Plug can be set in either open hole or casing and can expand up to 3 times its run-in diameter. The Plug can be run in on Drill Pipe/Tubing/Coiled Tubing and is inflated with fluid or gas by applying surface pressure. The high expansion ratio inflatable element provides reliable operation in wells with restricted inside diameters or open hole.
The design of the Permanent Inflatable Bridge Plug incorporates field-proven inflation system in conjunction with bi-directional inflation element as an integral part of a modular system that enables adaptability to a wide range of configurations and tool sizes.
Features
• Available in Bridge Plug or Cement Retainer configurations
• Can be configured with a dual-flapper valve system rated to 5,000psi (bi-directional seal established after disconnection/release)
• Incorporates a robust Inflation Valve System
• Adaptable to a wide variety of inflation element sizes
• Disconnect release mechanisms can be configured for right hand rotational release, direct pull release, hydraulic pressure shear or ON/OFF tool
• Inflation element construction features external anchoring designed to maximize anchoring for optimal differential pressure holding capability while maintaining an effective bi-directional seal
• Self-anchoring to maximum rated differential pressure capacity
• Large expansion capability – up to 3 times un-inflated diameter
• Conveyed on Coiled Tubing or Workstring
