ABERDEEN, UK -- Caledyne has achieved API 14A class 1 qualification for its Torus 2.9-in. (7.3-cm) insert value. The valve permits the installation of artificial lift or downhole monitoring in existing wells without the requirement of a full workover.

Testing for API 14A qualification involves analyzing gas and fluid leak rates. The Caledyne Torus safety valve recorded zero leakage throughout the testing process. Typical applications of the valve include liquid loading, scale build up, monitoring, and insert gas lift.

"The Torus valve allows various operations to be carried out, which in the past were unachievable, because the safety case could not be answered. We foresee a drive towards techniques such as installation of progressing cavity pumps offshore, which can deliver increased recovery of oil and gas assets at lower cost than at present," says Roland van Dort, managing director of Caledyne.
