CMIB Cement Manifold for Rotating Liner Systems | Schlumberger

CMIB

Internal-bypass cement manifold

Torque rated up to 50,000 ft.lbf [68,000 N.m]
Hook load rated up to 2,000,000 lbm [907,184 kg]

Manage cementing operations that require rotating or reciprocating a liner

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.

Configure plug or ball drops for your cementing requirements

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.
