EXETER, UK -- AnTech has added to its range of wireline in coiled tubing tools with the new Collector Bulkhead and a 2-7/8-in. (7.3-cm) Logging Head.
The Collector Bulkhead provides a means of connecting wireline to surface. The electrical connections are situated on rails that make it possible for one person to carry out installation and maintenance, single-handedly, AnTech says. The new Collector Bulkhead is available in both single and seven-conductor configurations to suit a variety of customer requirements, including ATEX options.
The addition of a 2-7/8-in. Logging Head provides a seven-conductor option for running video or open-hole tools. With the tool's modular design, it can be manufactured to meet customer-specified connections and cable sizes. The tools are available with a mechanical release featuring precision shear pins or an electrical release when a controlled release is required.
AnTech's Logging Heads feature a top connect that attaches to coiled tubing, and check valves that allow fluid to be pumped downhole, but prevent fluid from returning. In the event of an emergency, its cable weak point allows the cable to be broken downhole and pulled back. The electrical disconnect makes it possible to plan a separation of the head from the string.
In addition, all tool sizes have a fishing neck which means that operators can pull the separated string following a disconnect operation. Its non-rotating bottom connection makes it easy to attach to other tools located below when they are held by the grips of a BOP, AnTech says.
