Slickline or Coil-tubing

The SHARP System

The Slickline/Coil-tubing deployed, Hydraulically Activated Reliable Perforating system (SHARP system) is a hydraulically fired perforating system similar to systems developed for Tubing Conveyed guns. The system is designed to safely detonate perforating guns (for example, Tubing Punchers for zone switching) deployed on slickline in instances where an Electric Line unit is not available and depth accuracy is not absolutely critical.

FIRING PROCEDURE FOR SLICKLINE PERFORATING SYSTEM (SHARP)
      • Set a tubing plug for hydraulic isolation below the perforation interval
      • Pressure test tubing
      • Make up and Run gun to perforation depth
      • At depth, pressure tubing to predetermined pressure to shear calibration  pins
      • Hydrostatic pressure acting on the piston area of the firing pin slams the  pin down and fires the guns
      • The above system can be adapted for Coiled Tubing perforating
FIRING PROCEDURE FOR COILED TUBING PERFORATING SYSTEM (CTU-SHARP)
  1. Run tool to perforating depth. Steel-drop ball may be run in place. Tubing will fill with fluid as tool is run in hole
  2. At depth, pressure the tubing to approximately 2300 psi. The shear screw holding pump-out plug shears allowing the plug to move down and push on the Release rod. The 1/8" diameter Brass shear pin shears and allows the rod to move down. The steel retaining balls can now retract thus freeing the firing pin. Hydrostatic pressure (in excess of 400 psi) acting on the piston area of the Firing Pin slams the pin down and fires the Hornet Detonator
