Hydra MS WS Bridge Plug

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.

SAZ HydraHMTMHydro-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.

HydraHM Bridge Plug

SAZ HydraTTTM Through Tubing Bridge Plugs are designed for deployment inside tubing sizes from 3-1/2” to 4-1/2”. The Bridge Plug consists of a solid ring slip design and a swab proof packing element with positive anti-extrusion back-up rings, thereby providing a reliable isolation inside the tubing.

HydraTT Bridge Plugs are deployed on Wireline and set via appropriate Wireline Pressure Setting Assembly and Wireline Adapter Kit.When reaching the pre-determined depth, the pressure setting assembly is actuated and the tension mandrel in the adapter kit moves upward, pulling up the body of the bridge plug with respect to the setting sleeve, thereby setting and packing- off the Bridge Plug. Continued upward movement then shears the release stud, allowing the wireline pressure setting assembly and adapter kit tobe retrieved from the well.

HydraTT Bridge Plug

SAZ HydraWRTMWireline 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.

HydraWR Wireline-Hydraulic Retrievable Bridge Plug
SWR Retrieving Tool

SWRTM 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.
