The HydraCT™ System Was Developed to Make Rigless P&A a Reality
THE HYDRACT™ SYSTEM:
How it works
HydraCT™ offers an industry first PWC® system for rigless abandonment.
With a self-rotating, jet-propulsion tool, HydraCT™ is the ideal method for coiled tubing applications where there is no ability to rotate the workstring or if ID restrictions or limited load capacity exists.
Providing increased efficiency, HydraCT™ has the potential to:
Reduce costs by up to 60%
Cut CO2 emissions by 80%
HydraCT™ supports operators to run solely on coil tubing, eliminating the need for a rig or vessel, removing reliance on rig or vessel intervention. With no rig infrastructure, there are no rig costs.
WHY HYDRACT™?
Key Features
Can be run in wells with ID restrictions
Ideal when no rotation of workstring is possible
Hydraulic brake incorporated to control RPM downhole
High energy jets improve fluid displacement in the annulus
Manages ECD and prevents damage or losses to exposed formations
Operation
The HydraCT™ operation takes advantage of the incorporated jet-propulsed during the cleaning and cementing of the casing. Fresh wash fluid is pumped through the coiled tubing and the hydraulic brake section which transforms flow rate to RPM downhole. Rotation of the jetting tool cleans the annulus with multi-directional high energy jet nozzles which displaces the annulus content with the fresh wash fluid. Spacer is then jetted into the annulus prior to a ball drop isolates the wash nozzles and opens up flow through the cementing nozzles. The cement is placed with high energy jet nozzles accompanied by the elastomeric packer element – HydraDiverter – ensuring 100 % of the cement to exit through the perforations resulting a full cross-sectional cement barrier. The entire operation takes less than 24 hours to complete.
