AnTech Ltd has expanded its range of equipment for electric wireline in coiled tubing (CT).

As coil companies strive to maximise equipment capability, the number of CT operations has increased dramatically during the past five years. Those involved in CT operations are well aware of the fact that this effectiveness is substantially increased when electric line is installed in the coil. As a result, more and more CT operators are opting to use electric wireline CT. They realise that by doing so, they can offer more services because they can run a wide range of intervention tools on the system, and deliver greater benefits to their customers.

Every electric line CT operation requires equipment to effectively terminate the coil downhole and at surface. Reliable termination is absolutely essential because a fault will result in the run being aborted.

New Additions Enhance Logging and Perforating on Coil The company reports that four new items have been developed to facilitate logging and perforating on coil: • 8-way Collector Bulkhead, (10,000 psi) - utilises a bulkhead with seven-conductor feed-thru and boot assembly. • Electrical release for the 2-7/8' 7 conductor Cable Head - ensures reliable and safe termination downhole. • 1-¾ inch Single Conductor Cable Head -with electrical and mechanical release options for smaller tubing sizes and restrictions. • A Dual Polarity Electrical Release for multiple shot perforating operations that require positive and negative current for firing.

'The addition of these items bodes well for those carrying out logging and perforating jobs with electric line in coiled tubing. The development of two new Electrical Releases extends the tool's application in perforating where use of a mechanical shear release poses the risk of release upon detonation,' said Tim Mitchell, Product Line Manager - CT Tools for AnTech. 'To be safe, an electrical release should be used when perforating to achieve a controlled release, something that is not possible with a safety joint,' he added.

Already, AnTech has fulfilled orders for four logging head systems featuring the 8-way Collector Bulkhead, Electrical Release, 1-3/4' Cable Head and Dual Polarity Electrical Release for use in China and the Middle East.
