C4 System – Cut, Clean, Condition and Cement

Mechanical Perforator and Efficient Hole Cleaning Solution


The C4 system, by Lee Energy Systems, is a trip saving cut, clean, condition, and cementing solution where multiple operations are combined. The system offers an explosive free alternative to mechanically perforate, condition, and clean casing in well abandonment operations, prior to cementing.

The C4 system features four main components:

The Mega Packer offers a high expansion ratio, and when activated, provides a cement barrier in the A-annulus and a restriction in the B-annulus.

The Gator Perforator is equipped with four blades and is capable of achieving multiple circumferential cuts across the required zone.

The Jack Hammer features hydraulically activated jetting pistons that engage the perforations, creating an oscillating and jetting action simultaneously to both dislodge and clean the cement and debris behind the casing.
