WIRELINE AND PERFORATING SERVICES
VannGun® Assembly
4.00 in., 6 spf
The heart of Halliburton's VannSystem® service is the VannGun assembly. The VannGun
assembly uses bi-directional boosters, nonlead azide explosives, specialized connectors and
inserts, and high velocity-low shrink detonating cord. All these, as well as premium quality
gun material, are manufactured to Halliburton's proprietary specifications. The primary
design factors for these components are safety and reliability.
All VannGuns incorporate machined
scallops. This helps to optimize
charge performance and prevents
casing damage from perforating exit
hole burrs. Additionally, shot
phasing is designed to maintain the
integrity and collapse resistance of
the casing after perforating.
