HydraTech™ Downhole Wiper Displacement
The CleanWell® HydraTech® downhole wiper displacement tool changes conventional displacement processes. It provides a mechanical barrier that wipes the casing ID clean, while pushing mud into the drillpipe as the tool is descending in the wellbore. An intermediate fluid or completion brine is back filled into the annulus to replace the mud while tripping to bottom, saving critical rig time. Once on bottom, the design allows for the remaining mud in the drillpipe to be reverse circulated out, taking advantage of the high drillpipe velocities so that pit management can begin. If forward or conventional circulation is desired, the tool can be activated to restore standard pumping or displacement activities.
This tool is robust and promotes good industry practices such as rotation, reciprocation and the integration into single-trip intervention runs. The HydraTech tool is supported by Halliburton's drillpipe circulating (DPC) tool, which manages mud flow back at the surface. This tool is ideal for deviated wellbores. The solids or debris on the low side are forced into the drillpipe that would not be hydraulically removed through conventional circulating efforts.
The HydraTech tool is most commonly utilized with other mechanical wellbore cleaning systems, including the Drill Tech®, Bristle Tech®, Mag Tech® and Vali Tech® tools.
