Description / Application
The Bilco Flow Boy™ circulating tool is used to boost flow rates at liner tops, which is essential for proper well bore cleaning. This tool enables an efficient exchange of well bore fluids or spotting of chemical pills. The Flow Boy is always run in the hole with the ports closed and is opened through contact with the liner top. Flow Boy circulating tools offers two field-adjustable configuration modes. Depending on the configuration mode setting, once the tool is activated it either closes as soon as contact with the liner top is lost, or it remains open and is only closed again when contact with the liner top is reestablished.
Operation
The Flow Boy circulation tool is dressed for each job with regards to liner size and PBR ID. A landing nut below the shifting sleeve contacts the liner top or PBR. Tool activation is achieved by using string weight, only approximately 3000 pounds of down weight is needed to accomplish activation. As described above, once activated the tool operates in one of two possible modes. All circulation should be halted while activating or shifting this tool, to prevent seal damage.
