HydraMS Mechanical Set Bridge Plugs are deployed on Tubing or Drill Pipe and set by Snap Latch Setting Tool in either tension or compression. The large internal bypass prevents swabbing during running and retrieval. The bypass closes during Bridge Plug setting and opens during retrieval to enable pressure equalization before releasing the upper slips.

HydraWS Wireline Set Bridge Plugs are deployed on Wireline and set via appropriate Wireline Pressure Setting Assembly and Wireline Adapter Kit. This deployment offers customer a safe and efficient method of placing a drillable Bridge Plug at any predetermined point in the casing without having to dump cement on top to prevent leakage.

HydraWSB Wireline Set Bridge Plugs are available from 2-3/8” to 4-1/2” casing sizes. These Bridge Plugs are constructed with single piece elastomeric packing elements thereby providing an economical means for zone isolation, fracturing and other wellbore treatments. The small OD helps in speed and safety while running in.

HydraWSM Wireline Set Bridge  are available from 4-1/2” to 13-3/8” sizes. These high performance Bridge Plugs contain three piece Elastomeric Elements with metallic back-up rings on either side of the Elements to avoid rubber extrusion in high pressure and high temperature environment. For larger plugs deployed in 9-5/8”, 10-3/4” and 13-3/8” casing sizes, the three piece packing elements are replaced with a single piece element, with option to retain the three piece element design.

SAZ HydraHM^TMHydro-Mechanical Bridge Plug is hydraulically actuated and mechanically set,thereby eliminating the need for an external mechanical or wireline setting tool. These Bridge Plugs can be run and set in tandem with retrievable production packers or squeeze packers. The plugs offer customer flexibility on deployment for zonal isolation, squeeze cementing, fracturing, and Plug & Abandonment.

HydraHM Bridge Plug internal setting mechanism consists of Ball Seat, Setting Sleeve and Shear Stud. To set the Bridge Plug, a setting ball is dropped from surface and pressure is applied which sets the upper slips. Then the work string is picked up in tension which sets the packing element. The work string is then released by either shearing the shear stud or rotating 10 turns to the right.

SAZ HydraWR^TMWireline or Hydraulic Set Retrievable Bridge Plug is a high-performance Retrievable Bridge Plug that can be deployed on wireline or jointed pipe and retrieved via jointed pipe. It is ideally suited for temporary wellbore isolation without killing the well as the plug can be deployed and retrieved under pressure.

The high pressure from above and below thereby offering customer flexibility for temporary zonal isolation, acidizing and surface equipment repairs like well head replacements by safely keeping the wellbore fluids under control.

HydraWR Bridge Plug is deployed on wireline and set via the Wireline Adapter Kit attached to the Pressure Setting Assembly. It can alternately be lowered on Tubing and set via the Hydraulic Setting Tool connected to the Wireline Adapter Kit.

SWR^TM Retrieving Tool is run in hole and latched on the HydraWR plug with 5 to 10k lbs set down weight.  This enables the differential pressures across plug to equalize and a 10 to 15k lbs overall releases the HydraWR Bridge Plug from the casing wall for safe retrieval.
