The TT-TFH is designed to run and fully set either bridge plugs or cement retainers inside 2 3/8 or 2 7/8inch tubing on coiled tubing then squeeze in one trip.

 

Run the TT-TFH/SVCR tool string below the predetermined setting depth, pick-up to removeslack, drop a ½” diameter brass ball then, pressure the workstring to establish a 1,000-psi differential atthe tool to begin the setting process.

 

Continue pressuring the workstring to establish a 2,000-psi differential at the tool and hold for 5 minutes.This allows the cement retainer packing system to conform to the tubing ID.

 

Continue pressuring the workstring to establish a differential at the tool to shear the cement retainer or
bridge plug disconnect.
