The Retrievable Bridge Plug is a high-pressure packer type plug used for multiple zone and selective single- zone treating and testing operations such as acidizing, fracturing, cementing, and testing. The retrievable bridge plug is designed with a large internal by-pass to reduce swabbing when running and retrieving. The by-pass closes during the setting of the plug and opens prior to releasing the upper slips to equalize pressure when unsetting. The by-pass is located directly below the upper slips to help debris wash when the by-pass is open.
The Retrievable Bridge Plug has the added feature of being able to set and pack off the element in tension, making it ideal for setting shallow to test well head equipment and also deep, high pressure wells.
