The Multi-Cycle Circulation Sub is a highly versatile and robust drilling valve specifically engineered for use in drilling operations and Wellbore Clean-Up Bottom Hole Assemblies (BHAs). It features a straightforward dart drop mechanism, which facilitates the repeated opening and closing of circulation ports. This valve may be utilized independently or as a modular component within the ArmRdillo™ Wellbore Clean-Up System.
Features
- Simple 100% shut drop dart activation
- Dart activation is advantageous for ERD wells because of the Dart’s design and flow characteristics.
- Unlimited activation between open and close
- Large port total flow areas
- Isolates tools below when ports are open
- Partial Split flow dart available
- Tool position indicated by SPP
- Available sizes, 4-3/4”, 6-3/4”, 8-1/4” & 9-1/2”
Benefits
- Increases Well Productivity
- A properly executed wellbore clean-up reduces fine debris which can block screens and pore throats reducing well productivity
- Integrity
- The Multi Cycle Circulation Sub can be provided with any type of rig end connections including premium and high torque connections, reducing the need for reduced strength crossovers
- Reducing Non-Productive Time
- A robust wellbore clean-up is proven to reduce non-productive time during the completion of the well
- Reduces premature failure of drilling equipment by debris which can interfere with valves, electronics and other hardware
