Paradigm Flow Services, the blockage removal experts for the oil and gas sector, has launched Flexi-Coil Extended Reach to take riser and flowline blockage remediation and internal inspection to new lengths. The company is now calling on North Sea oil and gas operators to collaborate on trailblazing applications for the technology.
Conventional methods for remediating riser and flowline blockages are limited due to deployment difficulties and inability to overcome bends and safely navigate beyond 200 m. Flexi-Coil Extended Reach has been proven in tests up to 2000 m. As the technology continues to be enhanced, Paradigm is positive of its potential to tackle more than double that distance to 4000 m. The firm is currently undertaking major projects with an international operator in West Africa.
The system, based on miniaturised coiled tubing principals, can be deployed in-situ into risers and flowlines and currently provides the only safe solution to unblock these lines when working from an FPSO. The innovative system can carry out high pressure jetting, chemical and nitrogen injection over long distances, to de-sand, de-wax and de-pressurise hydrate plugs.
The industry can save operators tens of millions of pounds and solve blockage and restriction issues within a few days. Lines that may have been shut in for months or years can be remediated, restoring flow and enhancing oil recovery.
Rob Bain, Managing Director of Paradigm Flow Services, said: “Flexi-Coil Extended Reach is game changing, taking proven coiled tubing technology and adapting it in a way that makes it applicable and viable for the remediation of production systems. The only other option at the moment is to disconnect risers and bring another rig on site to carry out conventional coiled tubing. The safety and logistical implications have rendered this option redundant.
