Pumpdown plug and liner wiper plug for liner cementing
Separate cement from displacement fluid during liner cementing operations and then drill out rapidly.
The CMIB Light internal bypass cement manifold is well suited for smaller rigs on land where weight and handling are constraints. The CMIB Light is used to control the flow of cement and displacement fluids during liner cementing applications with a top drive 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.
A CMIB Light unit comprises an internal bypass manifold with modular ball-drop and plug-drop assemblies. The 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 Light 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.
