BD/CT (Ball Drop/Coil Tubing) Hybrid System
The BD/CT Hybrid system has all the proven features of our conventional ball drop sliding sleeve approach with some added benefits.During the first fracturing sequence, standard Ball Drop technology is employed on a single frac sleeve. After all of the BD/CT sleeves are opened and fractured then the ball seats are drilled out. At this time, the sleeves can be closed and re-opened using the activation tool on coil tubing. This allows for selective re-fracturing, acid work or simply isolate of certain sections of the string.
The BD/CT Hybrid system enables completions with up to 36 stages. In addition, high temperature and high pressure options allow for this system to be used in the most harsh environments in all of the unconventional reserves.
BenefitsPacker and sleeve combination provides for a simple open hole completion.
Initial ball drop technique requires less intervention and complexity in the completion process
The hydraulically actuated Launch sleeve enables circulation without perforation gun
You can select the sleeve you want close and re-open during future well intervention work
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 with hanger and isolation packers
The BD/CT sleeve uses standard Ball Drop technology during the initial fracture
After the initial fracture, the seat is drilled out and the sleeve can then be closed and re-opened for additional fracturing or acidizing.
