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 Plug Setting Aids Matrix 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.

Halliburton is proud to be a distributor for this tool and its technology. The CST tool is designed to create a physical barrier between a cement plug and the fluid below the plug. The purpose of this barrier is to prevent slumping of the heavier cement into the fluid below the plug. The basic operation of the CST tool consists of loading the tool inside the work string at the surface, pumping it down hole with a dart until it exits the work string and spotting a cement plug above the tool. Features • The CST tool is predominantly made from aluminum and composites and fabricated in a way that it can be folded together like an umbrella inside the work string. • Once exiting the pipe, it will unfold out and fill the hole. • The membranes will then fill the ID of the hole and help prevent wellbore fluid below from mixing with the cement. • Multiple cement plugs can be set in the wellbore with multiple CST tools with only one trip in the hole. • The CST tool can be pumped or placed before the prejob circulation. • The dart displaces the CST tool and prevents contamination in the string. • No other plug support is required as long as formation integrity is adequate to support the cement hydrostatic column, and hole geometry is fairly smooth and within maximum ID. HAL25019 CST Tool and Installation Case • In horizontal or uphill wellbores, the CST tool can be placed at TOC to prevent slumping at the top as it also supports from below. • The CST is commonly used for off-bottom plug cementing applications such as plug and abandon, kickoff, anchor for cased hole whipstock, and other remedial work. Optional Equipment Placement Dart and CST Tool Case • A specially designed diverter tool has been designed and is currently available to aid in hole cleaning and work in unison with the installation of the CST tool.
