Description
Bridge Plugs of STA series are designed to provide tight separation of cased hole intervals.
Application
- in well remedial and insulation works using bridging material in above-packer zone;
- during installation of bridges and temporary disabling of reservoir zone;
- during abandonment of wells or conservation of oil reservoir.
Design Features
- Setting is carried out hydraulically;
- Do not require special setting device;
- Sensitive to pressure differential in both directions: top down, bottom up.
- Made of easily drillable materials.
