A distinguishing characteristic of such perforation systems is the detachable swivel joints, which consist of the devices for receiving and transmitting detonation. The units remain intact after the triggering of shaped charges, which allows to use the chains of perforation systems up to 500 m long. This increases the efficiency significantly and expands the scope of the devices.

Other benefits of the Snake BVT:

  • a universal system for transferring a detonating impulse between sections;
  • swivel joints accelerate stripping-down and reassembly of the systems during tripping operations in wells;
  • the sections of perforation systems can be assembled in gun loading facilities, and the initiating module can be attached to them at the well;
  • guaranteed safety and performance of the devices.
