ZoneGuard® SR Isolation Packers

Halliburton's ZoneGuard® SR (Short Radius) isolation packer is designed for situations where tight radius well conditions are anticipated. The packer uses a multi-durometer element package with a unique back-up and deployment system to deliver unsurpassed sealing performance in a wide range of openhole conditions. The design features an anti-preset feature to help protect against premature setting of the packer during running operations. The packer can be used for zonal isolation in formation control, selective stimulation and fracturing applications.
