Clean and Circulation System
The Jack Hammer, by Lee Energy Systems, is part of the WIS C4 system (Cut, Clean, Condition and Cement). The tool is setup with a Packer diverter to force the annular flow through the B-annulus area and features hydraulically activated jetting pistons.
Once the perforations are complete, the oscillatory jetting jack hammer would then be deployed at the perforation interval and the washing sequence would start.
This will allow for an efficient clean as the jetting and inpat forces will be used to dislodge any debris cement barite or other materials that might be trapped between the two casing strong or the B Annulus.
