HydraCT - coiled tubing PWC
The HydraCT System Was Developed to Make Rigless P&A a Reality
Page last modified
August 21 2025
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 exist.
Providing increased efficiency, HydraCT has the potential to reduce costs and cut CO2 emissions.
HydraCT supports operators to run solely on coil tubing, eliminating the need for a rig or vessel, and removing reliance on rig or vessel intervention. With no rig infrastructure, there are no rig costs.
Pros & Limitations

Jet-induced turbulent flow, improved fluid displacement
1
Superior operational predictability
1
Manages ECD and prevents damage or losses to exposed formations

How it works
|
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.

Established in 2008, HydraWell recognised it was time for a new approach to Well Integrity. Traditional methods were cumbersome, and the industry was crying out for something unique. Something quicker, slicker, and safer. Hence, Perf, Wash, and Cement (PWC) was born to remediate well integrity issues and deliver safe well abandonments. We continue to identify and develop systems to solve these challenges, always seeking improved, more cost-effective, and safer approaches to well integrity and abandonment. Every day, we deliver effective well barrier solutions for leak prevention.
HydraWell is not only focused on relentlessly engineering improved solutions to replace traditional downhole techniques that introduce QHSE risks to well integrity operations. We are also committed to reducing environmental impact through the use of our ingenious technologies. We have a deeper sense of responsibility that is beyond delivering P&A operations. Our vision is to continue improving and evolving our solutions, operations, and approach so we adapt to the future. Using our expertise, we accelerate positive change in the energy sector to help improve the world we all live in.
