Halliburton’s ChannelSeal® Process can enable slurry to fill washouts and completely surround casing prior to cementing. Because ChannelSeal slurry remains fluid with low gel strength for extended periods and reacts shortly after the cement is placed, it can provide isolation in channels created by poor displacement efficiency in the primary cementing process.
The ChannelSeal process is designed for wells with temperatures ranging from 110°F to 300°F, and it is available in water- and synthetic-based slurries.
The ChannelSeal process can:
Improve shoe integrity
Minimize low-side channeling in highly deviated wellbores
Control cross flow
Temporarily plug sidetracking spotted through the bottom hole assembly
Assist in directionally drilling a new wellbore
ChannelSeal slurries are formulated for:
Maximum displacement efficiency
Maintaining a stable wellbore during casing runs
Minimizing channels and contamination over specific intervals
