Features

• Functioned by manipulating string weight with out the use of darts or balls
• Can be opened and closed multiple times without limitation
• Shear ring is available with several shear ratings to suit requirements
• Can be used when milling or drilling operations
• Reverse circulation capability before and after shearing
• Robust splined drive system for torque transmittal
• Robust assembly method with back-ups
• Compatible with other OWS ArmRdillo™ wellbore clean-up tools

Benefits

Cost savings

• The LCT-Liner Top 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 LCT-Liner Top 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

Applications

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

Operational

• The LCT- Liner Top Circulating Tool can be run independently or as part of a comprehensive wellbore clean-up string
• The LCT- Liner Top Circulating Tool has an integral landing sleeve which lands out inside the Liner Top PBR
• Whilst 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
• To close the tool ports pick up off the liner top
