AnTech Limited, a leading UK design engineering and manufacturing company serving the upstream oil and gas industries, has significantly expanded its Wellhead Outlet range. In addition, the entire range is now fully IECEx-certified.

Since 2001, AnTech has been supplying ATEX-certified, single and dual conductor Wellhead Outlets. Today, the wireline, completions and coiled tubing drilling specialist announced two new options: the triple conductor and the fibre optic line. The Wellhead Outlet is used in permanent completions where pressure and temperature must be continuously monitored. It connects the downhole cable to the surface telemetry system, and is attached to the wellhead to provide a safe connection between the cables and seal against downhole pressure. The configuration ensures that the integrity of the wellhead is maintained, even if the downhole cable is flooded.

Increased use of fibre optics triggers demand Having developed a bespoke fibre optic Wellhead Outlet for a major service company, AnTech is now making a system available to the global market. It is working on numerous enquiries to provide a fibre optic alternative to operators and service companies around the world. “We always aim to develop products that arise from specific demands from the marketplace, and the fibre optic Wellhead Outlet is no exception,” said Tim Mitchell, Sales Manager at AnTech. “Well before we created a custom-built system for our customer, we had been receiving enquiries for a fibre optic option. We’re confident that the new system will be embraced by the global market, just as our Wellhead Outlet range has been during the past 10 years,” he added.

Triple conductor design offers simple, safe connection With the growth in multi-drop intelligent completions, there has been an increase in the number of conductors required and power requirements downhole. In response AnTech has developed a new triple conductor option to further enhance its range which features both single and dual conductor Wellhead Outlets. With its innovative connector and cablehead, the triple conductor design offers simple and safe connection, while retaining the same configuration as AnTech’s existing outlets. With the introduction of the fibre optic and triple conductor options, AnTech now offers solutions for nearly every type of wellhead seal and downhole line. With single, dual, triple and fibre optic solutions available, AnTech aims to meet all customer requirements and become the leading provider of ATEX- and IECEx-certified Wellhead Outlets worldwide.

IECEx certification = approved for use in Hazardous Zones 1 and 2 In response to customer requests, in addition to the European-based ATEX certification, AnTech has obtained IECEx certification for its Wellhead Outlet range. The IECEx certification applies to all wellhead outlets used in wireline applications in hazardous areas Zones 1 and 2. AnTech offers a standard temperature and high temperature option for all electrical variants. The high temperature option can be used in wells with an ambient temperature (Ta) of 160°C operating safely in the temperatures typically generated by the majority of High Pressure - High Temperature (HPHT) wells. Other Wellhead Outlets in the range are certified for use up to 90°C.

Industry Efforts to Improve Safety and Performance Drive Sales With the industry’s increased commitment to safety and performance, sales of its Wellhead Outlets continue to rise. AnTech remains focused on supporting and developing this ever-expanding range. Since developing the first Wellhead Outlet in 1994, AnTech has sold more than 600 units to service companies and operators around the world.
