PCT (Pure Coil Tubing) System
The PCT system is designed for selectively stimulating multiple zones in a vertical or horizontal wells.The PCT Frac Sleeve can be run in an open hole or cemented well bore. The PCT system has no limit on the number of sleeves that can be run in a single well bore. The PCT sleeves open independently using the activation tool on coil tubing. With the activation tool in place, frac fluid can be pumped down the ID of the coil, the annulus of the coil or both.
The PCT activation tool utilizes a continuous J-slot to activate the locator keys for positive location and anchoring into each sleeve. Each sleeve is independently opened upon reaching a preset differential pressure inside the sleeve. After stimulation, the coil is picked up, opening the unloader valve. This resetting of the activation tool to the running position allows for moving up to the next sleeve.
BenefitsPacker and sleeve combination provides for a simple open hole completion
Full bore ID – no need to mill out ball seat
Activation tool is simple design with heavy duty reinforced cups for durability
Fracture fluids can be pumped down the coil, coil annulus or both
PCT system allows for reverse circulation in order to clean out on top of the shifting tool
FeaturesFor sizes: 2-7/8” to 5-1/2” completions
Capable for High Temperature, High Pressure, vertical, or horizontal applications
All components are designed to work in open hole and cemented wellbores
Unlimited number of sleeves
Uses coil tubing shifting tool to open the sleeve
The barrier for fracturing isolation is provided by the packer system on the shifting tool
