The company has supplied its first sequential DAV MX configuration for both multi-position and multi-cycle hole cleaning and displacement bypass in a single string, providing sustained activation angles of up to 82° in sections of more than 4,000 ft (1,219 m).
In addition, the company’s HyPR Hole Saver is said to be safeguarding multiple Norwegian wells against stuck pipe cost overruns.
Another in-house development, the Ultra Series Dart, is allowing various Norwegian operators to activate faster while pushing the standard differential pressure operating envelope by up to 50%, Churchill claims.
Finally, the company says its Emergency Shut-Off Dart is providing the operators with a way of mitigating risk when they find themselves pushed outside the operating envelope due to difficult well conditions.
