Plug Setting Aids
The CST™ cement support tool, tubing release tool (TRT), bottomhole kickoff assembly (BHKA) disconnect tool, and bottomhole kickoff assembly (BHKA) tool system were designed to aid in setting balanced and competent cement plugs during remedial and primary cementing operations. These tools, when used with cementing best practice applications, can help to improve the attempts to get a proper cement plug set the first time without the need for additional plugs. These tools are available to order through your nearest Halliburton sales office or field camp. Additional application information and product data can be supplied upon request. The following Matrix can help you select which tool can offer the most benefit for your cement plugging operations.
