Welltec Coiled Tubing Tractor and Jetting Head
GoFlo® is a new flow remediation system Halliburton has developed to remove restrictions and blockages from subsea flowlines and pipelines. GoFlo reinstates flowlines and pipelines, providing a quicker, less costly and more environmentally-sound solution than line replacement.

GoFlo deploys smart composite coiled tubing into flowlines and applies a combination of chemical, mechanical and thermal treatments to clear blockages. Halliburton offers a suite of remediation solutions that help eliminate restrictions and blockages caused by viscous organics, hydrates, scales and mechanical/debris.

GoFlo® Benefits
   •  Economics: Costs less than pipeline replacement
   •  Time: Minimizes downtime
   •  Environmental impact: No subsea disconnection of blocked flowline
   •  Production: Minimizes production downtime

This flow remediation system provides a complete and effective deepwater flow assurance service. Depending on the flowline configuration, the service can be deployed from one of Halliburton's or Subsea 7's specialty vessels or directly from a production facility, through the riser.

GoFlo's capabilities are:
   •  Maximum reach capability: Targeted at 20 miles (105,000 feet), depending on flowline configuration
   •  Working pressure: 5,000 psi
   •  Working temperature: up to 180F
   •  Entry speed: up to 50 feet/minute
   •  Retrieval speed: up to 150 feet/minute
