• Applications
– Used in most well applications and geometriesfor vertical, horizontal extended reach drilling, close tolerance, or underreamed well conditions
– Specialized in centralization for underreamed sections
Features of slip on integral centralizer
– Non-welded
– Integral bow design for increased strength and performance
– Zero weak points, such as hinges, welds, or mechanical interlocks
– Flexible to absorb both axial and radial loading
– Powder coated
Performance of slip on integral centralizer
– Zero start and running force with exceptional restoring force
– Improved flow by area and improved pipe rotation
– Low torque and low drag units
– Improved zonal isolation
