Hollow Carrier High Shot Density (HSD) Systems

Hollow Carrier High Shot Density Perforating is a high-performance expendable system with various sizes and configurations for tubing, liner and casing perforation applications. The steel-case charges mounted on a load tube inside retrievable hollow scalloped carriers are deployed via wireline (WLP), tubing (TCP) or coil tubing (CTP) depending on the wellbore trajectory, reservoir conditions and production objectives. The HSD carriers are fully recovered after perforation, leaving minimal debris in the well.

  • Charges are available in Deep Penetrating (DP) and Super Deep Penetrating (SDP) and Big Hole (BH) versions.
  • Charges may be loaded with RDX, HMX or HNS (special order upon request).

  • Carriers are available in up to 6 meters (20 ft) lengths, special lengths can be made upon request.
  • Carriers and adaptors are available with thread connects as provided in the specifications, other thread types and connection profiles can be made upon request.
  • The system can be supplied in either imperial or metric lengths.
  • The maximum O.D. corresponds to the maximum measured carrier diameter including burr and swell, on a carrier fired at atmospheric pressure immersed in water and/or air (note: measurements provided in the specification tables for carrier testes in the air, correspond to ExelteQ charges only).
  • For operations in high H2S content environment, special equipment must be used.

Time Temperature Curve

Downhole temperature will determine the type of shaped charge and detonating cord to be used. Refer to below Chart-1 for temperature versus time curve. These two factors determine the appropriate O-ring seal material to be used in the assembly. Based on Chart 2 below, Viton O-rings are recommended for Tubing Conveyed Perforating (TCP) systems and Nitrile O-rings are recommended for wireline applications.
