Inflatable Bridge Plugs
AGE Developments design and manufacture a range of inflatable bridge plugs. These permanent plugs have the advantages of small relative run-in diameter, large setting range and the ease of installation which is typical of AGE inflatable packers.
These bridge plugs were specifically designed for the plugging of wells prior to abandonment, as part of usual cementing procedures.
Features include:
• Suitable for setting in open hole or casing.
• Available to suit standard casing sizes.
• Factory set spring check and relief valve systems assure positive pressure shut-in and prevent over-inflation.
• Shear valve inflation protection system to prevent premature inflation.
• Lifting points provided on both ends of all plugs to facilitate handling.
Although normally used in conjunction with a cement grout plug set on
top of the packer, these bridge plugs can also support considerable
differential pressure from either above or below.
This range of standard plugs are principally designed for setting in casing. They employ a fixed-end inflatable packer element with synthetic cord and steel wire reinforcement. Specifications for standard 13 3/8", 20" & 30" Bridge plugs are as follows:

These plugs were originally designed to enable running through BOP restrictions and set in larger diameter casing. Owing to their large expansion capability, they are also useful for open-hole applications. They employ a sliding end, inflatable packer element, fully reinforced with steel wire.
