1. TCP Equipment Specifications

1. All explosive shall meet the safety standard API RP 67.

2. All perforating systems shall be tested according to the API RP 19B Section 1, Recommended Practices for Evaluation of Well Perforators.

3. The equipment shall be designed for H2S and CO2 service where requested by Husky, as dictated by expected well conditions.

4. The gun system shall withstand the maximum expected bottom hole pressure.

5. The gun system shall be compatible with the well fluids both prior to and after firing.

6. The guns system shall be designed such that, with the detonating device/ firing head connected to the perforating guns, and with the string being rigged up/down or deployed across the rotary table, detonation (from any cause) of the guns is prevented by at least two independent safety devices/arrangements.

7. Time-Temperature charts are required for all explosives that specify a documented stability after the maximum exposure time at temperature to avoid auto detonation.

8. Swelling and bending of guns after perforating shall be documented by testing the gun systems with the actual charges in the intended environment (gas or liquid).

9. Only Explosive designated as “Secondary” may be utilized in the gun string. Primary explosives are only allowed in detonators to be installed in firing heads

10. Hollow carriers with scallops should be used when running non-oriented gun systems. Strip guns should only be used where inner diameter prevents a hollow carrier gun system.

11. Guns without scallops are to be clearly identified as such to differentiate them from pipe. This identification should be easily visible regardless of weather, time, rotation or position.

12. Guns assemblies shall be clearly marked on outside and sequentially numbered. The loading section shall be marked with top and bottom shot.

13. Gun body connectors shall be designed such that they can be broken to release trapped pressure prior to mechanical separation.

14. Gun string connections shall be designed having two seals each individually capable of preventing the ingress of well fluids.

15. Detonators that do not require radio silence shall be validated by an independent, recognized testing agency and approved by Husky prior to first-time use on Husky’s installations.

16. Percussion detonators exposed to well fluids or unprotected are not allowed.

17. Firing heads that use detonators or initiators that require radio silence shall not be permitted.

18. Explosives in the firing head assembly and guns shall be isolated from well fluids by at least two seals, each independently being capable to withstand the system design pressure at the system maximum design temperature.

19. Only top mounted firing heads are permitted. Bottom mounted firing head are prohibited. For selective firing of guns on electric line, one of the firing heads is allowed to be installed in the bottom of the string.

20. For oriented perforating systems, the orientation of the perforation tunnels shall be within ± 10 degrees of the specified guns phasing in a 10 degrees/30 m dogleg. The system shall include orientation confirmation devices.

21. A safety spacer shall be installed between the firing head and the top shot to ensure that when the firing head is installed, the top shot shall always be below the rotary table while the firing head is connected. The top firing head shall NEVER be run as part of the top gun. This means the safety spacer had to long enough to put the top shot below the rotary after the slips are in and the safety clamp is installed. A minimum 3m safety spacer shall be installed between the tubing conveyed perforating firing head and the guns. This is not applicable for electric safe-type (wire line) firing heads.

22. Perforating guns shall be transported and stored with end caps including a device permitting pressure relief in case the pressure inside the gun build up if exposed to excess heat or fire.

23. The perforating system should include an auto-release device to drop the guns after perforation. The remaining part of the gun release sub has to act as a wire line re-entry guide.

24. The maximum size of the debris left in the hole shall not exceed 10 mm in diameter. This shall be documented by an accepted test procedure.
