Liner hanger systems
Enhance well stability and protect the casing.
Our internal-bypass cement manifolds (CMIBs) can be used to control the flow of cement and displacement fluids during liner cementing applications with a top-drive system on the rig. The CMIB creates a flow path for cement and displacement fluids without allowing them to pass through the rig's top-drive assembly, preventing cement contamination of the top-drive components.
The Standard CMIB unit is suited for most oilfield applications. The Ultradeepwater CMIB unit is designed for rugged applications requiring high hook loads. Both can be operated with a remote control unit. The Light CMIB unit is designed for smaller rigs on land and wells at shallow to intermediate depths.
A CMIB unit comprises a swivel and a manifold with modular ball-drop and plug-drop assemblies. The CMIB one-piece swivel housing eliminates threads, flanges, and welds while increasing strength and reducing the bending loads on the inlets. Drop mechanisms are self-contained for low maintenance.
A CMIB head can be configured for single-plug, dual-plug, or single-ball-drop operations. They are suitable for running and cementing all types of liner hangers, including rotating and reciprocating liner hanger systems such as the COLOSSUS CMT cemented liner hanger system.
Eliminating a dedicated liner run through a high-loss gassy salt zone reduced rig time by multiple days.
