MULTI-LATERAL-ENTRY-SYSTEM

The CE Coiled Tubing Multi-Lateral Entry System is designed to allow controlled repeatable entry of the desired lateral wellbore. The system consists of a Torque Through Slip Connector, a Motor Head Assembly, a High Torque Indexing Tool, a Hydraulic Knuckle Joint and a Pump Out Choke Probe. A CT Flow Control Valve can also be used to allow circulation without activating the Multi-Lateral Entry Tools. The CT High Torque Indexing Tool rotates the tools below it by 30° position each time the BHA pressure is cycled (15° & 45° positions are also available). Continuing to pressure up the tool string activates the Hydraulic Knuckle Joint which kicks over the Choke Probe. The Probe is suitably sized so that the Hydraulic Knuckle Sub will not be fully articulated unless the BHA is located at the casing window position. The casing window position is located by cycling the High Torque Indexing Tool and picking up and lowering the tool string. When the casing window position is found, a pressure drop will be observed by the operator as a positive indication that the Hydraulic Knuckle Sub is fully articulated and the circulation port opens. This CE Coiled Tubing Multi-Lateral Entry System can be used to enter multiple laterals in a single trip and is commonly used for Multilateral cleanout work operations. A very similar system is also used for jetting tunnelling applications.

FEATURES AND BENEFITS

Each component of the CE CT Multi-Lateral Entry System includes the following features to maximise its performance:

– The CT High Torque Indexing Tool produces high torque values to ensure the entire BHA is oriented each time the pump is cycled

– The Hydraulic Knuckle Sub delivers a large articulation force to ensure a reliable hole finding

– The Hydraulic Knuckle Sub features a bleed port to generate a positive pressure indication, every time the casing exit window has been located

– The choke in the Pump Out Choke Probe can be sheared out to enable high cleanout rates to be pumped, once the desired lateral has been effectively located

– Can be used for any Jetting Tunnelling Applications
