Inflatable Bridge Plugs

Inflatable Bridge Plug AGE Developments designs and manufactures a large range of inflatable bridge plugs for offshore applications. Our bridge plugs are specifically designed for the plugging of bores prior to cementing as part of standard abandonment procedures. These permanent plugs have the advantage of a relatively small run-in diameter, a large setting range and the ease of installation which is typical of AGE inflatable packers.

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.

Standard Casing Bridge Plugs

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:

Nominal Size O.D. mm (in) Rubber Length
mm (in)
Inflation Volume
Litres (gal)
Differential Pressure Capacity

Unsupported kPa
(psi)
13 3/8" 270 (10.63") 900 (35") 19 (5.0) 6500 (950) 2500 (360)
20" 434 (17.1") 800 (32") 24 (6.3) 6500 (950) 2500 (360)
30" 582 (22.9") 980 (39") 186 (49) 2000 (300) 800 (115)

Open Hole Large Expansion Bridge Plugs

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.
