The Alpha H-M Bridge Plug is set using hydraulic power to set the top slips and then mechanical pull to complete the set. The Model P is for high pressure and temperature while the Model E sustains moderate temperature and pressure.
The need for a mechanical setting tool does not exist because the setting mechanism is built-in. A ball is placed in the tubing string plugging off the built-in equalizing ports. Pressure is then applied to set the top slip and then mechanical pull is applied to finish the set. Releasing the tubing string from the plug is achieved by right hand rotation, leaving a full tubing ID for cementing, circulation or deployment of other equipment throught the workstring if desired. If needed, emergency shear release is available by overpull on workstring.
