The Wellpro Group Annular Flow Tool can be run into the well to improve and enhance wellbore cleanout efficiency during intervention or as a replacement for the conventional drop ball circulating sub.
The tool can be run in conjunction with motor and mill operations but can also be utilised in cleanout BHA’s.
This multi cycle tool can be switched numerous times and allows standard flow thru operations while running into the wellbore. By simply increasing the flowrate to a predetermined rate the tool switches and full flow is diverted to the work string annulus thus closing off all standard flow. When flow is reduced the tool reverts to standard flow through operation.
