Weight Set Circulating Tool by 


  The WCT- Weight Set Circulating Tool is a robust and simple circulating tool which can be opened and closed by string manipulation. It is typically run above a Liner Top to allow circulation of the casing above the liner. The WCT- Weight Set Circulating Tool is available to suit common casing and liner combinations.

Application
•  Pre-completion wellbore clean-up operations which include a larger diameter casing and a smaller diameter liner

Features
• Functioned by manipulating string weight without the use of darts or balls
• Can be opened and closed multiple times without limitation
• Shear ring is available in several shear ratings to suit requirements
• Robust splined drive system for torque transmittal
• Robust assembly method with back-ups
• Compatible with other OWS ArmRdillo™  wellbore clean-up tools


Operational
• The WCT- Weight Set Circulating Tool can be run independently or as part of a comprehensive wellbore clean-up string
• The WCT- Weight Set Circulating Tool is typically spaced out with a OWS Liner Landing Sub or Top Dress Mill below it which engages a Liner Top in the wellbore. A smaller diameter drill string hangs below the tool which extends close to the bottom of the well
• While running in the hole, the string can be reciprocated and rotated to allow the scrapers and other tools to clean the critical depths
• When required the tool is functioned by applying and maintaining string weight to allow circulation of the casing through the opened tool ports
• Chemical pills can be pumped to displace the liner and casing separately and more accurately than using conventional ball activated tools
• Pick up to close ports

Benefits
Cost Savings
•  The WCT- Weight Set Circulating Tool significantly reduces the time to displace wells by allowing the large casing above a liner to be displaced separately
• Reduces chemical consumption and brine filtration when used in combination with a well-engineered chemical displacement
• The WCT- Weight Set Circulating Tool can be opened and closed at exactly the right moment to accurately spot pills reducing waste volumes

Increases Well Productivity
  A properly executed wellbore clean-up reduces fine debris which can block screens and pore throats reducing well productivity

Reducing Non-Productive Time
•  A robust wellbore clean-up is proven to reduce nonproductive time during the completion of the well
