Our wide selection of gun sizes and system configurations provides the full range TCP solutions for well testing to safely and effective meet our clients well test objectives. These can be one-trip systems, run with the test sting or if a seal-bore packer is used, the guns can be hung from the packer or stabbed-through as required. Fully redundant firing systems ensure success and can be configured to perforate multiple zones independently without intervention. A range of mechanical and auto-gun releases can be incorporated to allow for access across the producing zones, e.g. for PLT passes. Run in conjunction with our DST tools a nitrogen or liquid cushion can be circulated into the tubing for static or dynamic underbalanced perforating.
