Dry environment
The Well Cleaner Dry Environment (DE) is designed specifically for cleaning in dry environments.
The auger at the tip loosens the debris and transports it into the bailer sections of the tool.
The Well Cleaner DE is run in combination with the Well Tractor® to apply weight-on-bit as necessary and to counter reactive torque.
Featured case
A horizontal SAGD well with wire wrapped screen configuration experienced a production decline. There were well-known sand problems in the well...
The Well Cleaner with rotating heads for Dry Environment is designed specifically to remove deposits left on the walls or completion components in the well.
Over time, these often lead to decreased production or malfunctioning hardware. The Well Cleaner’s different rotating heads remove these deposits to restore full functionality and production.
