Wood Group launches Thermal Moderator Tool to Melt Hydrates in Oil & Gas Flow Lines & Pipe

Wood Group Wood Group has launched a new hydrate liquefying tool to melt ice and paraffin blockages that occur in the production pipes of oil & gas wells.

The Thermal Moderator Tool (TMT), developed by Wood Group Logging Services, can be used in pipes with inside diameters as small as one inch. The tool, which is rated to 15,000 PSI of pressure, can be dispatched anywhere in the world and was recently dispatched to offshore West Africa where it was used to clear a blocked well.

"This new tool is portable and can be run in coiled tubing, flow lines and other small-channel transfer systems," explained John Paul Jones, president of Wood Group Logging Services. "The TMT was developed in response to requests from customers who wanted a non-chemical solution to eliminate hydrate blockages. It performed well in several test wells and is being used successfully in commercial operations, saving both time and money over traditional methods."

Wood Group (John Wood Group PLC) is an international energy services company with approximately $5.0bn sales, employing 28,000 people worldwide and operating in 50 countries. The Group has three businesses - Engineering & Production Facilities, Well Support, and Gas Turbine Services - providing a range of engineering, production support, maintenance management and industrial gas turbine overhaul and repair services to the oil & gas, and power generation industries worldwide.

Wood Group Logging Services specializes in cased-hole well logging, pipe recovery, vertical & horizontal perforating, TCP, casing inspection, production logging and high-pressure/high-temperature bond logging. Wood Group Logging operates in 20 locations along the U.S. Gulf of Mexico, and in West Texas and West Virginia.

Hydrates can be expected at low temperatures around the ice point and high pressures, conditions common to deepwater oil and gas developments. Hydrate formation occurs most frequently during shut-in and start-up as the flowline is usually at its lowest temperature.
