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.
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 180°F
Entry speed: up to 50 feet/minute
Retrieval speed: up to 150 feet/minute
